As part of our XWiki Days we had our second Improvement Fixing Day on the 7th of August 2014. Its goal was to close the maximum of JIRA issues of type "Improvement" by taking low-hanging fruit and taking the occasion to clean up our improvement list (duplicates, won't fix, etc).
We had 3 participants and we managed to close 14 improvements (12 real fixes).
FTR here's the graph of all non bugs.
Thanks to all the participants!
