-## [Unreleased]
+## [0.5.9] - 2026-06-10
+
+### Added
+
+- MXFP4 and NVFP4 4-bit quantization support across ID/filename parsing, VRAM
+  estimation, quality penalties, speed efficiency, and family grouping.
+  Repos shipping these formats were previously labeled FP16 and their VRAM
+  requirement overestimated about 3.5x. (#99)
+- Apple M5-family entries for `--gpu` simulation. (#92)
+- Kepler-era Quadro bandwidth and compute capability entries. (#75)
 
 ### Fixed
 
+- AMD discrete GPU detection on Linux: rocm-smi names are read from the
+  correct `Card Series` key, compound lspci names such as
+  `Navi 22 [Radeon RX 6700/6700 XT/6750 XT ...]` resolve bandwidth, sysfs VRAM
+  enriches the fallback path, and discrete cards are no longer mislabeled
+  `shared memory`. Adds RX 6750 XT / RX 6700 / RX 6650 XT / RX 6600 series and
+  Radeon AI PRO R9700 to the bandwidth catalog. (#61, #68)
+- Community GGUF repos without `base_model` metadata (for example
+  `unsloth/...-GGUF`) now inherit the official model's benchmark score by
+  name matching instead of falling through to no evidence. (#94)
 - GPU bandwidth detection no longer depends solely on the hand-curated
   catalog. When a detected card is missing from `GPU_BANDWIDTH`, bandwidth is
   now resolved from the bundled TechPowerUp database (dbgpu, 2824 GPUs) using
