Changes

[1.7.2] - 2026-02-05

  • Fix a bug where upload-yocto-symbols and upload-elf-symbols would fail on Python 3.14 with tarfile.AbsoluteLinkError when extracting tarballs that contain absolute symlinks (e.g. Yocto's /etc/localtime).

[1.7.1] - 2026-01-13

[1.7.0] - 2025-12-15

[1.6.0] - 2025-04-23

  • Add support for uploading ELF files without DWARF debug info.

[1.5.0] - 2024-11-14

  • Add support for Python 3.13: remove unnecessary version constraints on the chardet + lxml dependencies.

[1.4.0] - 2024-11-12

  • Populate a User-Agent string in the headers of all requests to Memfault Cloud to identify the CLI version used for diagnostics. Previously the User-Agent was only included for chunk POST requests.

[1.3.0] - 2024-11-07

  • Remove support for Python 3.6 + 3.7

[1.2.0] - 2024-08-28

  • Add the upload-software-version-sbom command. Look at the SBOM docs for more info.

[1.1.0] - 2024-07-22

  • Add a user-agent string to chunk POST requests to identify CLI version used for diagnostics.

  • Fixups with ruff (RET504)

[1.0.11] - 2024-06-28

  • Add an option --no-check-uploaded for upload-mcu-symbols to skip an initial check if the symbol file already exists. This option should be used with Org Tokens limited to only uploading symbol file

  • Bump urllib3 dependency to 1.26.19

  • Fixups with ruff 0.4.10

[1.0.10] - 2024-06-13

[1.0.9] - 2024-04-04

  • Add Miniterm help text when launching the memfault console command, to indicate how to exit the console (Ctrl-]).

1.0.8

  • Add Apache 2 license

1.0.7

  • Fix bug when deactivating delta releases when multiple deployments match the filters.

1.0.6

1.0.5

  • Add support for deactivating delta releases.

1.0.4

  • Add upload-elf-symbols command for uploading ELF files with debug symbols built outside of a Yocto environment
  • Add upload-elf-coredump for uploading a Linux coredump to Memfault

1.0.3

  • Fix a bug where upload-aosp-symbols would fail when uploading too many files at once.

1.0.2

  • Fix a bug where upload-yocto-symbols would fail when some files in the tarballs provided did not have the read permission set.

1.0.1

  • Fix upload-custom-data-recording to print a more helpful error message when exceeding device rate limits.

1.0.0

Note: this release is marked as 1.0.0 but does not contain any breaking changes! The version number was bumped to reflect the maturity of the tool.

  • Fix upload-mcu-symbols to skip uploading if the symbol file has already been uploaded, and return a zero exit code in this case

0.18.1

  • Add the --deactivate option to deploy-release, which disables a release for a cohort

0.18.0

  • Add new extra-metadata option to upload-ota-payload to attach custom metadata to that OTA release. The metadata will be returned from Memfault Cloud when fetching the latest Android OTA release.
  • Continue uploading the entire folder of symbols even if any single upload fails due to the symbol file being too large.

0.17.0

  • Add new console command to read SDK exported chunks via a serial port and automatically upload to Memfault.

0.16.0

  • Add support for uploading Android debug symbols from alternative build systems.

0.15.3

  • Warn if a non-slug string is passed to the --project or --org arguments

0.15.2

  • Don't truncate help output from click when the CI environment variable is set, for consistent output formatting

0.15.1

  • Fix some compatibility issues for python3.6 + python3.7

0.15.0

  • 💥 Breaking change: update the upload-yocto-symbols subcommand to take two image paths as required arguments; one for the root filesystem image, and another for the debug filesystem image. Versions 0.14.0 and lower used to take a guess at the path of the debug filesystem image from the value passed to the --image param. To avoid confusion and to support all configurations, the Memfault CLI no longer does any guessing and now takes two separate params: --image and --dbg-image

0.14.0

  • ✨ Update the post-chunk subcommand to split uploads into batches of 500 chunks per upload, to avoid timing out when uploading very large chunk logs

0.13.0

  • 💥 Breaking change: Renamed subcommand upload-debug-data-recording to custom-data-recording

0.12.0

  • ✨ Added subcommand upload-debug-data-recording for uploading debug data files

0.11.0

  • ✨ Enable support for Yocto Dunfell based projects (previously supported Kirkstone only)

0.10.0

  • ✨ Upload-yocto-symbols now uploads additional symbol files

0.9.0

  • ✨ Expanded support for .elf uploading with the upload-yocto-symbols subcommand

0.8.0

  • ✨ Initial support for upload-yocto-symbols subcommand

0.7.0

  • 🐛 Updated to correctly only use the GNU build-id .note section
