+## [0.4.5] - 2026-07-05
+
+### Changed
+
+- Dropped the upper bounds on `torch`, `triton`, `pylate`, and `colpali-engine`
+  so downstream envs resolve them freely. Dev-tool caps (`pytest`, `ruff`, `ty`,
+  `numpy`) stay, since they never reach downstream installers.

 ## [0.4.4] - 2026-06-10
 
 ### Fixed
