 This month in RubyGems, we released the following version of RubyGems [3.5.0](https://github.com/rubygems/rubygems/blob/master/CHANGELOG.md#350--2023-12-15), [3.5.1](https://github.com/rubygems/rubygems/blob/master/CHANGELOG.md#351--2023-12-15), [3.5.2](https://github.com/rubygems/rubygems/blob/master/CHANGELOG.md#352--2023-12-21), [3.5.3](https://github.com/rubygems/rubygems/blob/master/CHANGELOG.md#353--2023-12-22) and Bundler [2.5.0](https://github.com/rubygems/rubygems/blob/master/bundler/CHANGELOG.md#250-december-15-2023), [2.5.1](https://github.com/rubygems/rubygems/blob/master/bundler/CHANGELOG.md#251-december-15-2023), [2.5.2](https://github.com/rubygems/rubygems/blob/master/bundler/CHANGELOG.md#252-december-21-2023), [2.5.3](https://github.com/rubygems/rubygems/blob/master/bundler/CHANGELOG.md#253-december-22-2023). These updates mark significant milestones in our continuous effort to enhance the Rubygems development experience.
 
+With the yearly minor version release of rubygems 3.5 and bundler 2.5, we have dropped support for Ruby versions less than 3.0.0. This enables the usage of more modern features of the Ruby language, improving efficiency, performance and memory usage as well as reducing our test runtimes and removing the more error prone Ruby 2.6 and 2.7 tests. We spent time this month modernizing the codebase to take advantage of this change.

 A major enhancement was made to the `generate_index command`. It now has the capability to create compact index files. This feature has been integrated into the externally available `rubygems-generate_index` gem ([#7085](https://github.com/rubygems/rubygems/pull/7085)). This advancement not only improves efficiency but also extends the command's utility.
 
 The `gem install` command also saw an important update. To better accommodate environments where permissions might be restricted, it now automatically uses the user’s installation directory when the default `gem home` is not writable ([#5327](https://github.com/rubygems/rubygems/pull/5327)).
