Friends:
I've committed several changes to the WorkingWiki code. One of them is
important for site administrators to know about before you upgrade your
wikis, and some of the others are important for wiki users as well.
1. For site administrators: from revision 873 on, the directory
structure where the project files are stored is changed. It will take
care of moving the directories from the old locations on its own, but
there is one exception: all your background jobs will be abandoned. So
you'll need to make sure everyone's background jobs are finished and
merged or destroyed before you upgrade.
2. There are no more "implicit project descriptions". What this means
to you is mainly that certain pages that used to just work will now have
warnings saying "Source file X does not belong to project Y. Click here
to add it to the project." Since you may not want these messages to
show on pages you show to the public, you'll want to look over those
pages and fix these complaints.
3. Instead of ".latexml.xhtml" files we now use ".latexml.html5" files
to display LaTeX documents in the wiki pages. In most cases this is
taken care of for you, but if you're explicitly asking for
.latexml.xhtml files on certain pages (some people are), you'll need to
switch to asking for .latexml.html5 instead.
4. When you save after editing and previewing, we used to do a slow
process of comparing all the project files and copying the ones that
were changed into the permanent project directory. Now we just replace
the permanent directory by the complete preview copy of the directory.
This is massively faster. But you should know about it, because if you
remove files in the preview directory, they'll end up being removed in
the permanent one. I mention it because you might have gotten used to
removing things during a preview without consequences.
There are details, and other changes, on
http://lalashan.mcmaster.ca/theobio/projects/index.php/WorkingWiki/ChangeLog.
The new version of WorkingWiki is committed to the Subversion
repository, and also uploaded to
https://sourceforge.net/projects/workingwiki/files/ for admins who
install from tarfiles.
As always, let me know if anything is puzzling or wrong.
