RSyntaxTextArea 2.5.4 (and all of its sister projects) are now available on GitHub, Maven and SourceForge! The biggest change for all projects is the migration from Ant to Gradle for builds. The primary motivation for this was to make it easier to create artifacts to put into Maven Central, as well as to tinker with something new. Thus, this is the first release where everything is available in Maven on day 1! Moving forward, artifacts in Maven will be a standard part of the RSTA release process.
But besides Maven integration, some other goodies were added too, such as syntax highlighting and code folding for Dart and D, as well as simple code completion for XML files. Check it out!
