## [0.4.0] - 2026-01-11
### Improved
- Updated build instructions.
### Added
- Extract mount matrix and apply it for accelerometers.
### Fixed
- Cleaned up white space.
- Fixed 2 memory leaks caused.
- Properly close QMI client.
- Do not initialize variables if not needed.
- Do not check for `NULL` when not needed.
- Move Xiaomi Davinci struct to private header.
- Add symbol list to avoid exposing more symbols.
- Deprecation warning of protobuf-c tool.
- Do not run tests if `Q_IPCRTR protocol` is not available.
- Skip tests on ARMv7/armhf due to floating point problems with protobuf-c decoding.
- Fix printf formats for sensor UIDs.

## [0.3.0] - 2025-12-26
### Added
- Gyroscope sensor support.
- Vala bindings generation.
- GObject introspection generation.
### Fixed
- Thread symbol leaking into global scope.
### Changed
- Drop reporting threads as these are not necessary.
## [0.2.2] - 2025-02-21
### Fixed
- Load libqrtr on Debian correctly for mocking SSC.
- Use `g_assert_no_error` in tests.
- Let meson look for Python instead of specifying the binary name when mocking.
- Add `g_cond` for report threads to avoid race conditions.
## [0.2.1] - 2025-01-12
### Fixed
- Mocking Protobuf messages are now stored in the right directory.

### Added
- Unittests for CI/CD.
- Mocking SSC DSP with ssc-server to emulate DSP on non-Qualcomm environments.
- Release instructions in RELEASE.md.
- Set `G_LOG_DOMAIN` during build to 'libssc' for easier debugging.
- Wait for DSP to become available during boot.
### Changed
- Reduced API surface. All private interfaces are now excluded from public usage.
- API is now solely exposed through `libssc.h`.
- Use proper GErrors instead of g\_warning for errors.
### Fixed
- Passing GTask in libssc-sensor was missing.
- Light sensor intensity is always positive, reject negative measurements.
- Proximity sensor will always output a measurement now when opened.
- Document availability sensor attribute and specify QMI header length.
- Path to protoc and protoc-c for compiling ProtoBuff messages.
- Public headers are now correctly installed.
- Sync API race conditions.
## [0.1.6] - 2024-06-08

## [0.1.5] - 2024-05-17
### Fixed
- Fixed LICENSE to properly indicate GPLv3.
- Add architecture diagram referenced in reverse engineering notes.
- Fix .so library name to avoid twice 'lib': liblibssc.so
### Added
- Timeout parameter for ssccli.
- Flush stdout after each sensor measurement in ssccli.
- Add support for proximity sensor of xiaomi-davinci (SM7150).
