+## [2.1.0] - 2026-09-28
+
+### Added

+- **Text fine-tuning parameters** — `bl finetune text create` now accepts job name, priority, LoRA, evaluation, checkpoint, dataset-split, and data-augmentation parameters. `bl finetune get` returns expanded job metadata and hyperparameters.
+
+### Fixed
+
+- **Windows Skill installation** — Handle legacy path limits and update installed Skills in place when running agents keep directories open.
+
+### Internal
+
+- Publish binaries before npm `latest` and ad-hoc sign macOS release binaries.
