Are you saying you've identified another concurrent performance  
hotspot in FreeMarker code? If so, I'd like to hear details.

We don't tend to have fixed schedules...  There's a good bunch of  
changes since 2.3.12, for now these are (copied from preliminary  
documentation update):
Bug fixed: [1725107] JspTaglibs with servlet spec 2.4 causes parser  
warnings.

Bug fixed: [1851842] OutOfMemoryError parsing a largish text chunk.

Feature: [1892546] Allow for custom template loader in  
FreemarkerServlet.

Bug fixed: [1902012] IteratorModel eats exception causes.

[1898300], [1818742], [1780882]: Reworked template caching mechanism  
for radically improved concurrent performance, with help from Azul  
Systems engineers. (Achieved 20x speedup with Struts2 webapps on a 128- 
CPU Azul device compared to 2.3.12.)


It looks to me as if it enough to warrant a release - what do others  
committers think? (Although I expect only Daniel will be interested in  
a 2.3.x release).
