 # Changelog
 
+## [0.2.0](https://github.com/sbrow/envr/compare/v0.1.1...v0.2.0) (2025-11-10)
+
+
+### ⚠ BREAKING CHANGES
+
+* Dir is now derived from Path rather than stored in the DB. Your DB will need to be updated.
+* **scan:** The config value `scan.Exclude` is now a list rather than a string.
+* **check:** Renamed the `check` command to `deps`.
+* The config value `scan.Include` is now a list rather than a string.
+
+### Features
+
+* Added new `check` command. ([cbd74f3](https://github.com/sbrow/envr/commit/cbd74f387e2e330b2557d07dd82ba05cc91300ac))
+* **config:** The default config now filters out more junk. ([15be62b](https://github.com/sbrow/envr/commit/15be62b5a2a5a735b90b074497d645c5a2cfced8))
+* **init:** Added a `--force` flag for overwriting an existing config. ([169653d](https://github.com/sbrow/envr/commit/169653d7566f63730fb9da80a18330a566223be9))
+* Multiple scan includes are now supported. ([4273fa5](https://github.com/sbrow/envr/commit/4273fa58956d8736271a0af66202dca481126fe4))
+* **scan:** Added support for multiple exports. ([f43705c](https://github.com/sbrow/envr/commit/f43705cd53c6d87aef1f69df4e474441f25c1dc7))
+* **sync:** envr can now detect if directories have moved. ([4db0a4d](https://github.com/sbrow/envr/commit/4db0a4d33d2b6a79d13b36a8e8631f895e8fef8d))
+* **sync:** Now checks files for mismatched hashes before replacing. ([8074f7a](https://github.com/sbrow/envr/commit/8074f7ae6dfa54e931a198257f3f8e6d0cfe353a))
+
+
+### Bug Fixes
+
+* **check:** `fd` now correctly gets marked as found. ([17ce49c](https://github.com/sbrow/envr/commit/17ce49cd2d33942282c6f54ce819ac25978f6b7c))
+
+
+### Code Refactoring
+
+* **check:** Renamed the `check` command to `deps`. ([c9c34ce](https://github.com/sbrow/envr/commit/c9c34ce771653da214635f1df1fef1f23265c552))
+* Dir is no longer stored in the database. ([0fef74a](https://github.com/sbrow/envr/commit/0fef74a9bba0fbf3c34b66c2095955e6eee7047b))
