+### 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.

 Dropped `typer` dependency for CLI.
