Release Process/Release Announcements

Wiki Changes
These are the changes currently needed to Wiki as part of Release Announcements.

 Go to http://bugzilla.audacityteam.org/buglist.cgi?cmdtype=dorem&remaction=run&namedcmd=Release%20Notes&sharer_id=5 to see the P1/2/3 bugs (including WONTFIX with those ratings). Export the .CSV. Feed it through http://www.catalase.com/bugzilla2wiki.htm to convert (some) to Wiki formatting  Copy the output from http://www.catalase.com/bugzilla2wiki.htm and paste it into the new Release Notes to replace the contents of the section "2 Known Issues at Release". If that section contains a sub-section "2.1 Headline issues" or other bug notices that are still required, paste underneath those sub-sections. Remove the second half of the paste which is the same content with colored tables, bug ratings and bugzilla links. Tidy up the formatting of the paste so there are no duplicate categories, missing or duplicate bullet points, broken links etc. As pasted, the most recent bugs are at the bottom of each bug category. Optionally, new important bugs could be moved to the top of their category and given a  anchor.  Add the "released on" date to the current Release Notes.  Go to Release Notes and add a link to the new Release Notes. Click the link on that page to the previous Release Notes and add there the end date so as to produce "was available from... until".
