-In January, we released new versions of bundler `v2.2.7` and `v2.2.8`, and rubygems `v3.2.7` and `v3.2.8`, the most important change being to fix resolver edge cases and speed up bundler - [#4277](https://github.com/rubygems/rubygems/pull/4277). This change makes bundler faster and the resolver more correct. We also keep refining our RFC for Bundler Version Locking -[#29](https://github.com/rubygems/rfcs/pull/29) and plan to move on to the implementation soon.
