TikiWiki 188.8.131.52 has been released! Thanks to all the developers for their hard work.
(184.108.40.206 fixes a blocking wiki edit bug in 1.7.1, sorry for the inconvenience)
Read on for summary of fixes and changes.
The main point in that release candidate is the fixed registration. It was blocking the rc2. If you use the 1.7rc2 you should upgrade to rc3. There is no db change, only some files fixed.
