Paul King commented on GROOVY-10879:
------------------------------------
Yes, we should normally wait for the 72 hour window in such cases. The 72 hour
window was probably up since the original emails but the issue itself was only
two days. But we haven't finalised any Groovy 5 release plans. Did you have
some ideas for improvements?
