### Added
- Restrict write permissions to the installing user.
  For several reasons we use `C:/RubyXXX` direcory by default but not `C:/Program Files` (see: oneclick/rubyinstaller#135 ).
  Using an install path under `C:/` previously inherited write permissions for everyone, which compromised security in a multi user environment.
- `ridk use` Add options to store the change permanently in the user or system environment variables. #314

### Changed
- Update to ruby-3.0.5, see [release notes](https://www.ruby-lang.org/en/news/2022/11/24/ruby-3-0-5-released/).
- Update of the SSL CA certificate list.
- Update the bundled MSYS2 keyring package.
- Fix start menu entry for rubygems-server.
- Run the ruby command prompt in the start menu with `ridk enable`.
- Update the start menu entry with the newly installed ruby version.
  They kept the old ruby version previously.
- Fix possible crash in `ridk use`. #291

### Removed
- No longer create registry keys under `Software\RubyInstaller\MRI\<RubyVersion>`. #242
  They weren't used any longer and didn't distinguish between 32 and 64-bit versions.
- No longer install the 32 bit but only the 64 bit version of MSYS2 as part of `ridk install`.
  It is still possible to get a pure 32-bit MSYS2 and Ruby installation by using the 32-bit RubyInstaller+Devkit package.
