As for other fixes, the inability to “Select all” that might have affected some users has been fixed. The fonts that lost anti-aliasing in v2017.1 have also become smooth again across all JetBrains IDEs.
If you are listening to our EAP channel, consider updating from the IDE (RubyMine | Check for updates) or downloading this EAP directly from our EAP page on Confluence.
See the release notes for the full list of improvements.
