## [1.23.0] - 2025-08-11
10+
11+
This release adds support for Python based stacktraces, as well as a few minor
12+
changes. Additionally we've made some changes to flash lifetime metrics, and how
13+
they're collected.
14+
15+
### Added
16+
17+
- Add generic custom trace support
18+
- This allows you to send text based backtraces to memfaultd.
19+
- They can be sent via the `memfaultctl save-trace` command
20+
- They can also be sent via `/v1/trace/save` local endpoint
21+
- Added Python stack trace support
22+
- Python stack traces utilize the above custom backtrace support
23+
- By integrating [pyfault](https://pypi.org/project/pyfault/) you can send
24+
backtraces directly from a crashing python process.
25+
- Add new virtual memory metrics from `/proc/vmstat`. These are represented as
26+
the following keys:
27+
- `memory/vm/swaps_in_per_second`
28+
- `memory/vm/swaps_out_per_second`
29+
- `memory/vm/pages_in_per_second`
30+
- `memory/vm/pages_out_per_second`
31+
- Added OUI (Organizationally Unique Identifier) collection for network device
32+
identification and troubleshooting
33+
34+
### Changed
35+
36+
- Changed flash lifetime metrics to use `pct_remaining` format instead of
37+
previous representation, providing clearer visibility into remaining device
38+
lifespan
39+
40+
### Fixed
41+
42+
- Fixed MMC lifetime reading where `memfaultd` would attempt to read lifetime
43+
values from older MMC devices that don't support this feature
44+
- Fixed handling of invalid individual lifetime values - they no longer cause
45+
the entire lifetime collection to fail
46+
- Fixed overly verbose device info logging that was cluttering log output
47+
- Fixed build configuration for macOS by removing
48+
`--compress-debug-sections=zlib` from cargo config that was causing
49+
compilation issues
50+
- Fixed unit test reliability by properly mocking `boottime_ms` values
51+
