mender 4.0.5

Released 12.02.2024

Changelogs

mender (4.0.5)

New changes in mender since 4.0.4:

Bug Fixes

Fix crash when Sync_Leave returns error during a deployment. The error message would be:
```
State machine event DeploymentStarted was not handled by any transition
```
and would happen on the next deployment following the Sync_Leave error. With a long polling interval, this could cause the bug to be latent for quite a while. (MEN-7379)
Fix systemd race condition when restarting mender from ArtifactReboot script. The symptom would be an error message like:
```
Process returned non-zero exit status: ArtifactReboot: Process exited with status 15
```
And the ArtifactReboot_Error state scripts would be executed, even though they should not.
Progress reader updates the output only when progressing (MEN-7159)
rootfs-image: Add missing filesystem sync when not using mender-flash.
rootfs-image: Make it safe to roll back after ArtifactCommit.
Fix error while loading OpenSSL config file, by explicitly initializing the SSL context prior to loading. Without the explicit initialisation of SSL, the config might not be properly loaded if e.g. it has sections specifying ssl settings. This was the case with the example configuration for OpenSSL 1.1.1w from Debian Bullseye. (MEN-7549)
Invalidate cached inventory data on unauthentication event to prevent an issue with which the client would not send inventory data to the server after being unauthorized and authorized again. (MEN-7617)
Fix possible integer overflow when dealing with large files on 32-bit platforms. (MEN-7613)
During Artifact header parsing, correctly report generic errors instead of returning "Multiple header entries found" error for any kind of error. (MEN-7721)
Verify the integrity of the version file content during Artifact parsing. (MEN-7721)
Fix potential integer underflow in Artifact's manifest parsing (MEN-7722)
Limit file name length for the Artifact manifest (MEN-7722)
Ensured strict permissions of private key files created by mender-auth (MEN-7752)

Other

Clarify in the update module protocol documentation that going into ArtifactRollback is still possible after an ArtifactCommit, and it must still roll back successfully. While this may seem like it introduces new requirements into a stable protocol, it's important to remember that this was always possible, if the device lost power after having run the steps inside ArtifactCommit, but before the device could record having done so. In this case ArtifactRollback would be the next step, so this is just formalizing this possibility and subsequent requirement.
Add info level messages for inventory sent/skipped

Changelogs

mender (4.0.0)

Mender client version 4.0.0 has been completely rewritten from scratch in C++. To ensure a successful migration, there are a number of changes which are important to pay attention to. The complete list of changes is below, but for a more user friendly migration guide, please see the Upgrading guide in the Mender documentation.

New changes in mender since 3.5.2:

Bug Fixes

disabled implicit conversion form Error to bool (MEN-6409)
README: add build instructions for C++-client
latest openssl reports "no such file" if the cert doesn't exist
Rootfs scripts in the C++ client are checked in the same way as Artifact scripts, and hence, we are now moving it to support only version 3. While in the old Golang client both version 2 and 3 were supported. (MEN-6671)
The client no longer erronously commits a rootfs-image artifact after being restarted using systemctl restart in the ArtifactReboot state. (MEN-6633)

Features

The client's HSM crypto-module support is changed so that the PrivateKey used for authentication is always taken from the configurations: security.AuthPrivateKey, and the HttpsClient.private_key is only used as the key for the associated certificate HttpsClient.client_certificate. The two can still use the same key, but this means now that you add the same key url in both places. (MEN-6668)

Other

The rootfs-image updater is no longer built in, but is an Update Module, available under the name rootfs-image.
Remove DbusEnabled config option.

Mender now always depends on DBus. (MEN-6662)
Remove BootUtilitiesGetNextActivePart and BootUtilitiesSetActivePart config options. These are not necessary anymore since the choice of tool, including its calling arguments, can be programmed directly into each update module instead. (MEN-6662)
Update Control support has been removed from the client. (MEN-6647)
--forcebootstrap is not a global cli option anymore, but an option specific to mender-auth daemon and mender-auth bootstrap commands. (MEN-6679)
Mender daemon does not anymore integrate with syslog, handling the logs is responsibility of systemd or the caller. (MEN-6679)
Global flag --no-syslog is removed. (MEN-6679)
Remove --passphrase-file option from command scopes where it has no use. Move it to mender-auth daemon and mender-auth bootstrap commands. (MEN-6679)
mention the deprecation of control maps (MEN-6648)
Mender client does not use HTTP Keep-Alive anymore. The related configuration option Connectivity is deprecated. The TCP connection will be terminated as soon as the HTTP request/response is finished, and every subsequent HTTP request will open a new TCP connection. (MEN-6862)
systemd service mender-client does not exist anymore. Dependencies shall depend either mender-authd or mender-updated. (MEN-6858)

mender 3.5.3

Released 06.12.2024

Changelogs

mender (3.5.3)

New changes in mender since 3.5.1:

Bug Fixes

Fix a rare bug which could corrupt the very end of a rootfs-image update on a sudden powerloss. The circumstances where it could happen are quite specific: The filesystem size in the update need to not be a multiple of the native sector size, which is very uncommon. The sector size is typically 512 bytes almost everywhere, and hence filesystem also follow this block size, if not bigger. The exception is raw Flash/UBI devices, where the sector size can be much larger, and not a power of two, and hence these platforms may be more susceptible.
doing so return 1 in Download_Enter state scripts aborts instead of retrying in an endless loop (MEN-6319)
Fix so the Download_error state script gets executed for failures due to signature (MEN-6402)
recover from a corrupted database renaming it as broken and starting with a new empty one (MEN-6848)

Changelogs

mender (3.5.0)

New changes in mender since 3.4.0:

Bug Fixes

The daemon no longer exits in the edge case where it cannot bring down the proxy server due to timeouts. (ME-3)
The websockets are no longer left trying to open a connection to the server, when the proxy server is shut down. (ME-3)
Expand the check for new openssl version
systemd: Always try restarting the client if it exits. (ME-33)
websocket connectivity through http-proxy if configured

Enables websocket connections to be established through an http-proxy configurable by setting the HTTPS_PROXY environment variable. This renders services that relies on websocket connections, such as mender-connect, compatible with http-proxying. (ME-5)
client not to skip custom TLS if an http-proxy is configured

Previously, Mender client supported http-proxying but ignored custom TLS client configuration if present. This change renders any custom TLS configurations, such as Mutual TLS, compatible with http-proxying. (MEN-6009)
do not ignore software versioning opts in the module artifact gens (MEN-6026)
Add --no-syslog to the service file to ensure no duplicate log messages in the journal. (MEN-6070)
change mender-inventory-hostinfo to use the output of hostname

Features

Install bootstrap Artifact on first start-up.

On start-up, Mender checks for the existence of an special bootstrap Artifact in path /var/lib/mender/bootstrap.mender and installs it in order to initialize the device database.

This applies both for daemon start and cli commands bootstrap and install.

The Artifact is not installed if the device already has a database. When the Artifact is not found (and the database is empty) the database is initialized with artifact-name=unknown.

In addition, Mender can also understand other kinds of "empty" Artifacts and install them either in managed or standalone modes. (MEN-2583)
Remove support for artifact_info file. The initial artifact name will be populated in the database using a bootstrap Artifact. (MEN-2583)
do not check if the artifact is already installed (MEN-6129)
Support multiple verifications keys

https://hub.mender.io/t/multiple-artifactverifykeys/4309/6

Creates a new client config parameter called ArtifactVerifyKeys that is a list of paths to keys. Any matching key can be used to verify an artifact - e.g. if 5 verification keys are provided, only 1 needs to match to verify the artifact.

Add a thread: field to the proxy logger

Now the proxy logger stands out in the logs more, and can thus be filtered easier with tools parsing structured logs. This means that a log line from the proxy thread goes from looking like:

Oct 05 08:50:06 qemux86-64 mender[259]: time="2022-10-05T08:50:06Z" level=error msg="error forwarding from client to backend: websocket: close 1006 (abnormal closure): unexpected EOF"

To:

Oct 05 08:50:06 qemux86-64 mender[259]: time="2022-10-05T08:50:06Z" level=error thread="proxy" msg="error forwarding from client to backend: websocket: close 1006 (abnormal closure): unexpected EOF"

The default folders (/etc/mender, /usr/share/mender and /var/lib/mender) can now be overridden through the environment variables: MENDER_CONF_DIR, MENDER_DATA_DIR, MENDER_DATASTORE_DIR.
Add zstd compression support

Replace obsolescent egrep with grep -E in inventory script

Changelogs

mender (3.4.0)

New changes in mender since 3.3.0:

Bug Fixes

setenv: Fix script input syntax.
rootfs-image-v2: Make sure to set mender_boot_part_hex
By default we bind to 127.0.0.1:0 instead of localhost.
Over D-Bus we return the ProxyHost equal to 127.0.0.1
Upgrade openssl dependency to fix cast error in recent Go.
If paused before ArtifactReboot, and then manually rebooting the device outside of Mender, the client will properly resume the update now, instead of failing and rolling back. (MEN-5709)
Append log entries to syslog at the correct level
The client update and inventory checks are now unaffected by the use of the check-update and send-inventory commands. While previously, this would both move the intervals at which checks we're done, and also extend them beyond the expected polling intervals configured. (MEN-5547)
Resolve symlinks for /dev/disk/by-partlabel

Changelogs

mender (3.3.0)

New changes in mender since 3.2.1:

Bug Fixes

Only fall back to older endpoints on HTTP 404's

Make the client only fall back to older endpoints on HTTP 404 error codes when polling the deployments/next endpoint.

Previous functionality fell back to older endpoints on all error codes. This in turn meant that when the client got rate-limited by the server on 429's, the client fell back to the older endpoints.

The problem with this is that only the POSTv2 endpoint supports control maps, so when an update with control maps was in progress, the other endpoints would return 204, and the client would think the deployment was aborted from the server. (MEN-5421)
Fixed an issue in which long-running systems, with a long time between reboots, and multiple updates encountered the Tried maximum amount of times error, due to an error in the retry logic.
Log the fallback to the artifact_info file at log level Warn, when the Artifact name can not be retrieved from the database.
add an After systemd dependency on mender-client-data-dir
The mender-client.service file now has an explicit After dependency on the data.mount target, to make sure it is mounted, before the client commences operation.
Fix Git error when installing after the fix for the CVE-2022-24765 Git vulnerability (Github's description of the issue). This also fixes a subtle "pseudo abort" issue which can occur in the Yocto build environment.
the HTTP proxy must bind on localhost, not on all the interfaces (MEN-5642)
Don't accumulate zombies when command output parsing fails. (MEN-5587)
Only capture module stdout when requested (MEN-5098)
Fix printing of update module stdout in real-time

Features

Allow to disable HTTP Keep-Alive from config, set idle timeout.
Inventory push retries and backoff.

We use RetryPollIntervalSeconds in inventory with the exponential backoff via GetExponentialBackoffTime together with a new setting:
- RetryPollCount -- the max number of tries
- inventory by default tries 3 times with one minute intervals (GetExponentialBackoffTime defaults)
RetryPollCount applies to all places where backoff is present

Other

Add alternate EFI path to mender-inventory-bootloader-integration
Add alternate EFI path to mender-inventory-bootloader-inte…
Add support for the GET /v2/deployments/device/deployments/{id}/update_control_map endpoint. (MEN-5542)

mender (3.2.0)

New changes in mender since 3.1.0:

[FIX] Fetch geo location data once per power cycle
The client now shows output from scripts executed in the log as regular log messages, prefixed by the filedescriptor they are written to, and the script executed, like this: 'Output (stdout|stderr) from command \"/usr/bin/foo\": bar.' (MEN-5098)
Bump github.com/mendersoftware/mender-artifact to 3.6.1
Fix error not finding active partition for systems where /dev/root is a symlink
installer/bootenv: support systemd-boot tools
Upgrade golang.org/x/crypto to the latest version
Title if the update module has not already requested a reboot. This is done, in the case that ArtifactInstall never finished, and hence the reboot information from the update module is never collected. (MEN-4882)
Upgrade from deprecated golang.org/x/crypto/ssh/terminal to golang.org/x/term (QA-235)
Mender starts a local HTTP server that will proxy incoming requests to /api/devices to the currently authenticated Mender server. The existing D-Bus API endpoints GetJwtToken and JwtTokenStateChange will now return the local address together with the JWT token. Supports also websocket upgrade when calling /api/devices/v1/deviceconnect/connect endpoint (MEN-5216)
mender setup: Deprecate --demo flag and split its functionality across new flags --demo-server to configure the device for a Mender demo server and --demo-polling to use demo polling intervals. (MEN-5138)
Client will no longer cache the Authorization token from the server across restarts, meaning that it is no longer possible to end up in the situation where a rootfs update with invalid authorization data succeeds, only to fail authorization later on when the token expires. (MEN-5217)
It is no longer possible to change the identity of a device with a rootfs update. This was not supported before either, but worked in a hacky way by abusing the authorization token to get a rootfs update with new identity data to succeed. Afterwards the device would show up as a new device when the token expired. (MEN-5217)
ubi: Get rid of useless warning: Could not resolve path link: ubi..
Refresh update control maps before failing an update

Fix the issue where if a state takes longer than the expiration time for the enabled update control map, then by the time the client checks its control maps, the map is expired, and the update fails.

Now the client refreshes the update maps from the server before each pause, and hence, this issue will be avoided. (MEN-5096)
Handle the possibility of losing network connectivity when refreshing the update control maps.
Fix a race condition which can happen during a reboot if systemd kills the reboot command before it kills the Mender client. (MEN-5340)
When an update is paused, the client now queries the server for updates using the UpdatePollIntervalSeconds interval if it is shorter than UpdateControlMapExpirationTimeSeconds, enabling quicker response when continuing an update.
Fix a (possible) file descriptor leak.
vendor: Bump mender-artifact to latest master version

Changelogs

mender (3.1.0)

New changes in mender since 3.0.0:

Fix a bug which could sometimes lead the client to do a rollback after it had already committed. This could happen if the client happened to spontaneously reboot or fail during the status update to the server. Doing this is not correct according to the state flow, and can have unexpected consequences depending on the combination of Update Modules and State Scripts. (MEN-4830)
mender-inventory-network: Fix incompatibility with busybox, by using short command line options in grep command. (MEN-4851)
Do not put useless and sometimes even incorrect zero values in the configuration file when running mender setup. (MEN-4857)
Extend logs for docker module
Add artifact_name to device provides if not found in store
Support passing docker run CLI arguments when deploying an artifact using the docker update module.
Implement support for non-U-Boot tool names. The tools still have to be command line compatible with the U-Boot tools (either u-boot-fw-utils or libubootenv), but the names can be different. This allows having U-Boot tools installed alongside grub-mender-grubenv tools, whose new names are grub-mender-grubenv-set and grub-mender-grubenv-print, instead of fw_setenv and fw_printenv. The two new configuration settings BootUtilitiesSetActivePart and BootUtilitiesGetNextActivePart have been introduced to configure the names. If no names are set, then the default is to try the grub-mender-grubenv tools first, followed by the "fw_" tools if the former are not found. (MEN-3978)
Add missing filesystem sync which could produce an empty or corrupted Update Module file tree in /var/lib/mender/modules/v3/payloads/0000/tree/files/ after an unexpected reboot.
If the mender.conf file has a new server URL or tenant token, the client will now remove the cached authorization token upon the next restart of the dameon, and hence respect the new configuration, as opposed to letting it expire, which was the old functionality. (MEN-3420)
[FIX] Fetch geo location data once per power cycle

mender (3.0.0)

New changes in mender since 2.6.0:

mender setup: when configuring for demo using self-signed certificate, install the certificate in the local trust store so that all components in the system (namely, Mender addons) can trust the Mender server without extra configuration. (MEN-4580)
Warn in the log when the system certificates contain the demo cert.
Dont Verify SSL if skip verify is set If skip verify is set , then we shouldnt call VerifyResult
Fix infinite carriage return output when running in ADB shell
Add a DBus endpoint for the UpdateControlMap, which allows a user to set the ID and Priority of a given update process. (MEN-4535)
The daemon will no longer crash if mender check-update or send-inventory is used before the daemon has finished its set up. (MEN-4074)
Update Modules Artifact generators: correct --software-version flag
single-file-artifact-gen: Support concurrent executions
single-file Update Module: fix rollback functionality
Add UpdateControlMapBootExpirationTimeSeconds to mender.conf.
The location of the device type file is now determined by the mender.conf file. If the device type file is not used in mender.conf, the device type file is determined by the --data flag and if the flag is not used, the device type file is set to default. In addition, the scripts and modules directories location is consistent with the --data flag now. (MEN-4669)
Implement the continue/pause/fail state machine logic This adds support for the explit control of the Mender state machine through the update control maps functionality. The state machine can be controlled through the verbs, puase/continue/fail in the states:
- ArtifactInstall_Enter
- ArtifactCommit_Enter
- ArtifactReboot_Enter (MEN-4549)
Fix D-Bus timeout on errors by finishing handling (MEN-4703)
Report to deployments/status when pausing in any state (MEN-4624)
Fix race condition in menderAuthManagerService due to concurrent map access. This could manifest either as a crash, or as a failure to deliver the JwtToken to dependent processes, such as mender-connect.
Fix race condition in dbus.RegisterMethodCallCallback due to concurrent map access. This could manifest either as a crash, or as a failure to deliver the JwtToken to dependent processes, such as mender-connect.
Fix: Correctly log the error response message from server errors
Fix occasional crash when exiting using SIGTERM.
Fix: mender-client.service and the old mender.service services can no longer run at the same time. If anyone has both, then mender.service should be removed from the system.
Previously the Mender client would hide output from the child processes it ran, leading to errors from tools such as fw_printenv, not showing up in the logs. Now default to showing all output from the child processes called in the client logs.
The client now supports the HTTP Device API v2. (MEN-4785)
Mark deployment as failed on bad signature instead of retrying.
CLI commands prefixed with hyphen are now deprecated, use instead directly the command name. For example mender daemon, mender commit, mender show-artifact, etc. (MEN-4808)
Remove deprecated flag --log-modules (MEN-4808)
Fix a bug which could sometimes lead the client to do a rollback after it had already committed.

Cache geo-location inventory data in volatile memory
Log which scripts are run at the info level
Filter out docker network interfaces in inventory This adds functionality for filtering out interfaces matching

mender (2.5.4)

New changes in mender since 2.5.3:

Fix error not finding active partition for systems where /dev/root is a symlink
Title if the update module has not already requested a reboot. This is done, in the case that ArtifactInstall never finished, and hence the reboot information from the update module is never collected. (MEN-4882)
Fix a race condition which can happen during a reboot if systemd kills the reboot command before it kills the Mender client. (MEN-5340)
Fix a (possible) file descriptor leak.
Bump github.com/mendersoftware/mender-artifact to 3.5.x

mender (2.5.2)

New changes in mender since 2.5.1:

Dont Verify SSL if skip verify is set If skip verify is set , then we shouldnt call VerifyResult
Update Modules Artifact generators: correct --software-version flag
single-file-artifact-gen: Support concurrent executions
single-file Update Module: fix rollback functionality
The daemon will no longer crash if mender check-update or send-inventory is used before the daemon has finished its set up. (MEN-4074)
Fix D-Bus timeout on errors by finishing handling (MEN-4703)
The location of the device type file is now determined by the mender.conf file. If the device type file is not used in mender.conf, the device type file is determined by the --data flag and if the flag is not used, the device type file is set to default. In addition, the scripts and modules directories location is consistent with the --data flag now. (MEN-4669)
Fix race condition in menderAuthManagerService due to concurrent map access. This could manifest either as a crash, or as a failure to deliver the JwtToken to dependent processes, such as mender-connect.
Fix race condition in dbus.RegisterMethodCallCallback due to concurrent map access. This could manifest either as a crash, or as a failure to deliver the JwtToken to dependent processes, such as mender-connect.
Fix occasional crash when exiting using SIGTERM.
Fix: Correctly log the error response message from server errors
Fix a bug which could sometimes lead the client to do a rollback after it had already committed. This could happen if the client happened to spontaneously reboot or fail during the status update to the server. Doing this is not correct according to the state flow, and can have unexpected consequences depending on the combination of Update Modules and State Scripts. (MEN-4830)

Released 09.11.2020

Changelogs

mender (2.4.0)

New changes in mender since 2.3.0:

keystore: use openssl bindings Switch the code that signs the server's authentication request to use openssl. This allows to use ssl_engines, which permit to use PKCS#11 or TPMs as keystore.
vendor: switch openssl bindings to github.com/Linutronix/golang-openssl spacemonkeygo/openssl depends on spacelog, which increases binary size by about 2MB due to using reflect. Switch to a fork which has the logger removed. This patch can hopefully be reverted someday, when the logger removal has been mainlined.
Log state-script stderr as info, not error (MEN-3316)
mender-inventory-geo script to return geo localization data
Add support for libubootenv as boot loader user space tools provider. (MEN-3684)

New changes in mender since 2.1.2:

mender setup cli command and new CLI package (MEN-2418, MEN-2806)
Fix UBI device size calculation
store: Save artifact provides for dependency verifications
app: Verify artifact (version >= 3) dependencies with current artifact
store/app{standalone}: Artifact dependency checking for artifact v3
app/store{standalone}: Unit tests Artifact v3 depends and provides
Enable the usage of the full Mender-Artifact version 3 format (MEN-2642)
support: modules-artifact-gen: Fix typo in default name of output file
Rename --mender-professional flag to --hosted-mender
Add --quiet flag and remove --run-daemon option and confirm device
Now the client stores Artifact provides parameters across reboots in standalone mode. Previously this data was ignored, and hence upgrading with an Artifact with provides parameters these were lost. (MEN-2969)
Set default device type to hostname for interactive setup
New command: snapshot dump to dump current rootfs
Skip special device "rootfs" when determining rootfs type
Report 'Unknown' rootfs type if we can't detect it
Optimize rootfs-update image writes (MEN-2939)
Make single-file-artifact-gen script POSIX compliant. (MEN-3049)
Fix segfault when running mender setup on a read-only filesystem.
Fix crash when specified certificate can't be opened. Both the ServerCertificate setting and the system certificates are now optional, in the sense that the client will run without them. However, the client will not be able to connect without the right certificates, so the main usecase of this change is to have a workable client that will roll back if connections can't be made, instead of exiting. (MEN-3047)
Add warning message when server certificate can't be parsed.
snapshot: Added watchdog timer to keep system from freezing
snapshot: Add compression options to speed up transfer
Improved error message when an update-module is missing (MEN-3007)

module/single-file: fix rollback state by correctly defining filename
Check for -f option in stat command
Set hard limit(10) for client update status report retries This fixes an issue where the maxSendingAttemps in updateReportRetry state could be set real high, since it is calculated as UpdatePollIntervalSeconds / RetryPollIntervalSeconds.

rootfs-image-v2: Make sure to follow the spec regarding stream-next. We should to read the final empty entry to make sure the client does not block.
Restore error code 2 behavior when there is nothing to commit.
Fix read error masking in installer.chunkedCopy(...) func
Update vendored dependencies for client.
When set, HTTP proxy settings in http_proxy/https_proxy environment variables are respected now.
module-artifact-gen: Fix inability to specify more than one device_type.
Make all errors checked or explicitly ignored All possible errors must be checked across all code base. If an error is intentionally ignored it should be done explicitly.
add state-scripts example scripts to wait for network connectivity before trying to connect to the Mender server. (MEN-2457)
Artifact gen: Support argument passthrough to mender-artifact. Use -- to signal that remaining arguments should be passed directly to mender-artifact.
Make the device type file location configurable
Make channel receiving user signals buffered The commit fixes improper usage of signal.Notify(...) func from Go stdlib. A channel must be buffered to properly receive signals: https://golang.org/pkg/os/signal/#Notify Also there is no need to reallocate channel and defer signal.Stop(...) each time user signal is received. Thus less resources are used.
standalone: Fix artifact committing not working after upgrading from 1.x. (MEN-2465)
Print warning on an invalid server certificate. (MEN-2378)
add state-script example to preserve ssh keys accross updates (MEN-2457)
Fix /bin/lsb_release not being picked up by inventory script.
Fix misspells in comments and error messages
Make sure ARM64 is included in bootloader integration inventory.
Added example to retain systemd network configuration.
single-file module: Make sure permissions are preserved. Also make sure that backup preserves permissions.
add state-script example to utilize dbus to broadcast Mender states (MEN-2457)
Provide command line interface to force inventory update. (MEN-2131)

mender 2.0.0

Released 05.07.2019

Changelogs

mender (2.0.0)

New changes in mender since 2.0.0b1:

Version files are now allowed to contain a newline character. Also some minor changes, as readVersion now accepts an io.Reader, and files are opened outside of the function. This means that the error message is now consistent for all the uses of readVersion. (MEN-2318)
file-install modules: Don't destroy original before we know we have a backup.
Fix File Install UM to not wipe out dest_dir on single file installs
standalone: Fix artifact committing not working after upgrading from 1.x. (MEN-2465)
Deprecate old file-install Update Module and create instead two new ones: single-file-install and file-tree-install. These have a simpler logic and clearer scope. See for details. (MEN-2442)
Don't push network interfaces without a mac address to inventory
Disallow installing file trees on root destination dir for File Install Update Module
Make sure ARM64 is included in bootloader integration inventory.
Mender no longer misidentifies LVM volumes. (MEN-2302)
Update modules: Implement NeedsArtifactReboot -> Automatic. (MEN-2011)

New changes in mender since 1.7.0:

Bugfix: State-script error code in Sync-Enter causes infinite loop (MEN-2195)
Allow rootfsPartA and rootfsPartB to be symlinks
Rewrite AuthorizeWaitState to fix an infinite loop bug (MEN-2195)
Modify design for exec.Cmd stdout/stderr logging
Place UM generator scripts in a dedicated folder (MEN-2371)
Write Update Module to do file(s) install (MEN-2371)
Set StateScriptTimeout default to 1h (MEN-2409)
Add source-installation instructions to README.md.
Add rootfs-image-v2 as a demonstration of how to reimplement Mender's rootfs-image update type as an update module. It's also useful as inspiration if users want to make their own slightly tweaked rootfs-image type. (MEN-2392)
Swapped definition of StateScriptRetryTimeout and StateScriptRetryInterval for the names to represent what they are actually doing. This change breaks compatibility with current usage of these configurable parameters. See documentation for correct usage. (MEN-2409)
Write update module for doing container setup (MEN-2232)
Add example update modules for shell commands and pkg installs.
Remove misleading warning message when ServerCert is missing.
Remove jq dependency for file-install Update Module
Implement initial version of update modules. (MEN-2000)
Add support for Mender Artifact format version 3. (MEN-2000)
Artifact name is now stored in the local database, and /etc/mender/artifact_info acts only as a fallback if no name has been stored yet. This is typically the case for devices provisioned directly from a disk image. Scripts should use the client -show-artifact argument instead of parsing the file. (MEN-2000)
-rootfs argument has been removed and replaced with the -install argument, which works the same way. (MEN-2000)
Mender now runs a stripped down set of state scripts when installing artifacts in standalone mode, and the -f flag is no longer required to install such artifacts, nor is it valid. The scripts that run are:
Download scripts
ArtifactInstall scripts
ArtifactCommit scripts
ArtifactRollback scripts
ArtifactFailure scripts Reboot scripts do not run, so these must be handled manually in standalone mode. (MEN-2000)
Behavior change: ArtifactCommit_Error scripts now run after an ArtifactCommit_Leave script has returned an error. (MEN-2000)
Bugfix in killing mechanism for State Scripts timing out (MEN-2409)
Update vendored dependency net/http2 to latest version
Support installing most files using Makefile install target. The device_type file is not supported, since it is highly hardware specific. Also the configuration will be very bare bones, and will require changes unless Hosted Mender is being used. (MEN-2383)
Make output from -show-artifact easier to consume by limiting logging.
Fix state logic for the case of actual wait (MEN-2195)
Properly fail the update when writes to the underlying storage fail. (MEN-2285)
Work around occasional OOM bug in mmc driver. (MEN-2285)
Make sure state directory is created if it doesn't exist.
