This release ist mostly about security and bug fixes and a few minor changes (We removed 4suite dependency for docbook formatter, using now minidom which is included in python). For details see: http://hg.moinmo.in/moin/1.9/raw-file/1.9.5/docs/CHANGES See http://moinmo.in/MoinMoinDownload for the release archive. BTW, for future moin 1.9 releases, we still need many more people helping with maintaining and updating translations on http://master19.moinmo.in/ . So, especially if you speak some non-english language, you can help! See http://moinmo.in/MoinDev/Translation for details. We spent most of our time on developing moin2, see http://moinmo.in/MoinMoin2.0 for details. One of the recent commits there was to make moin2 work on GAE based on work done by Guido van Rossum. If you like to hack / test new stuff, have a look! Also feel invited to help with it, so it gets ready for production sooner. If you are interested in helping, feel free to contact us on IRC chat, see: http://moinmo.in/MoinMoinChat
