 ## Unreleased
 
+## [0.1.3] - 2026-04-21
+
+### Changed
+
+- Removed `version` field from `info` section in lock file.
+  This field have been used to specify the Pyodide version used to create the lockfile,
+  but lockfile does not need to be bound to a specific Pyodide version.
+  If you need to check the compatibility between the lockfile and Pyodide,
+  you can use the `abi_version` field in the `info` section instead.
+  [#41](https://github.com/pyodide/pyodide-lock/pull/41)
+
+- Upgraded Python version constraint from 3.10 to 3.12.
+  [#41](https://github.com/pyodide/pyodide-lock/pull/41)
+
+## [0.1.2] - 2026-02-27
+
+- Added `UvPipCompile` compile class for experimental support for constructing
+  lock files using `uv pip compile`.
+  [#40](https://github.com/pyodide/pyodide-lock/pull/40)
+
 ## [0.1.1] - 2026-01-02
 
 Dropped `typer` dependency for CLI.
