Sorry to hear you feel the need to attack developers on their progress. It has actually been fixed in .20 which is currently at beta 3. Which to add, is our next release of the software, so actually the earliest release it could have been in.
In answer to your question
3 beta versions of the brand new beta 5 release, including thousands of bug fixes
3 public holidays, of which well needed time off was taken by developers
3 beta versions of .20 (of which actually include the very fix you are talking about)
Complete recreation of our site to be compatible with version 5 of the platform, in preparation for the first major release in over a decade
Movement of all cloud assets to a new storage system, which was quite a large undertaking
Adding in of new WAF to our cloud infrastructure for better protection of our customers
Your opinion wasn't the issue. Your language toward hard working staff was.
