The Groovy development team and G2One, the Groovy / Grails professional services company, are pleased to announce the release of Groovy 1.5.2 -- a bug fix release for Groovy 1.5. You can read the release notes for more precise information on the bugs that have been fixed.
Since the creation of G2One, this trend of bug fixing has been very positive, as shown on JIRA's report: more bugs resolved than open, yet another great maturity sign. Another current focus of the G2One team lately is related to increasing the performance of Groovy, through advanced call site caching techniques. The upcoming beta version of Groovy 1.6 will provide significant boosts in performance, so stay tuned!

If you are just beginning with Groovy, you may also wish to read an introductory series of articles on Groovy Zone, a new community news site about everything Groovy and Grails -- more articles of this kind are in the works.
