All notable WIMF changes are recorded here. The project follows semantic versioning for the Python package; container compatibility is documented separately.

- Retuned the default quality ladder from scale 1.5 to 2.5 (divisor stays 16)
based on the photo/natural RD sweeps: the lossy ladder gains a ninth usable

- Added a photo-like mixed-frequency pattern to the RD sweep corpus
(`tools/wimf_rd_sweep.cpp`) and refreshed the tuning workflow matrix around
the new default.
- Made WIM2 the sole recommended authoring format.
- Deprecated WIMF v1, the `.wif` filename alias, AWIF/v1 chrono, `ROT!`, watermark, legacy mip/depth,
`wimf-convert`, and `wimf-meta` authoring surfaces ahead of WIMF 3.0.
- Retained read-only compatibility and added a committed AWIF-era decode fixture.
- Limited CodeQL to first-party production code and documented bundled Zstandard 1.5.7 provenance.
- Unified public native/Python option validation and removed AWIF from performance benchmarks.
- Added NEON (ARMv8) and AVX2 (x86-64) SIMD acceleration for CRC-32 checksums and predictive filter encoding.
- Added content-adaptive wavelet quantization that scales with local tile detail.
- Improved Zstandard compression levels for all search presets (Fast 1→3, Balanced 6→9, Extreme 15→19).
