About Ruby 3.1 with MSYS2

The RubyInstaller project provides a self-contained Windows-based installer that includes a Ruby-language execution environment and a baseline set of required RubyGems and extensions, integrated with a MSYS2 installation.

What's new in 3.1.7-1

Changed
- Update to ruby-3.1.7, see release notes.
- Apply all security patches that Canonical provides for Ubuntu-20.04 because version 1.1.1 is out of maintanence from the OpenSSL project:
- CVE-2024-2511
- CVE-2024-4741
- CVE-2024-5535
- CVE-2024-9143
- CVE-2024-13176
- Fix automatic pacman package install when using bundler-2.5.x. #396
- Fix pacman install error in parallel bundler install -jX. #403
pacman invocation is now serialized to avoid locking errors.
- Update MSYS2 download version to 2024-12-08 for ridk install 1. #402
- Add junction (directory link) at <ruby>/ssl, which allows to easily find the OpenSSL certificates directory. #399
The certificates directory varies between ruby versions and the junction unifies the location.
It is described in <ruby>/ssl/README-SSL.md.
- Update the SSL CA certificate list.
- Remove installed gems and MSYS2 by the uninstaller per default. #408
So far the uninstaller only removed the ruby install files, but kept installed gems and MSYS2.
The old behaviour is available when running the uninstaller with option /allfiles=no.
See in the wiki.
This is to prepare RubyInstaller for the Microsoft Store.
- Avoid early load of etc.so allowing updates of etc.gem. #388
- Set a single key in gemrc to allow appending to this file. #388
