Updated Settings Sync plugin - Improved the behavior of the Settings Sync plugin. In previous RubyMine versions, if you used multiple JetBrains IDEs (possibly including different versions of RubyMine), settings in one IDE would be synced across all of them. To provide you with more flexibility, an Enable sync across different types of IDEs checkbox has been introduced in Preferences | Settings | Settings Sync. The checkbox is deselected by default, meaning that the settings will only be synchronized between different versions of RubyMine. If you want settings to be synchronized across all your IDEs, not just RubyMine, select the checkbox.
Support for a new type of ESLint configuration file - Added support for the new ESLint flat configuration file type, eslint.config.js, which was introduced in ESLint 8.21.0. These files are now detected and ESLint is executed without the –config flag.
