@ -38,6 +38,8 @@ This section contains the changelog from the last release to the next release.
* `libimagentryannotation` got a rewrite, is not based on `libimagnotes`
anymore. This is minor because `libimagentryanntation` is not yet used by
any other crate.
* imag now reads the `IMAG_RTP` environment variable before trying to access
`$HOME/.imag` for its runtimepath.
* Bugfixes
* `Store::entries()` does not yield StoreIds which point to directories
