Here are the topics that have been cooking in my tree. Commits prefixed with '+' are in 'next' (being in 'next' is a sign that a topic is stable enough to be used and are candidate to be in a future release). Commits prefixed with '-' are only in 'seen', which means nothing more than that I have found them of interest for some reason (like "it may have hard-to-resolve conflicts with another topic already in flight" or "this may turn out to be useful"). Do not read too much into a topic being in (or not in) 'seen'. The ones marked with '.' do not appear in any of the integration branches, but I am still holding onto them. The first batch of topics for the new cycle are now in 'master'. The second batch will primarily be to graduate 'ort' as the default. I've been a bit under the weather during the last week and wanted to concentrate on what to push out to 'master', so while I may have picked up new topics and replaced existing topics with their new versions, I haven't added or updated my summaries on their doneness to this document. Help is appreciated. There also may be other patches sent to the list that I haven't looked at, whether they were reviewed by others or not. Copies of the source code to Git live in many repositories, and the following is a list of the ones I push into or their mirrors. Some repositories have only a subset of branches.

Sometimes, it is useful if the files named by configuration variables can be made optional (it would allow ~/.gitconfig to give a filename, and make it effective only in repositories that have a file with that name). This uses an extra variable that marks that the variable is optional. Yet another alternative is being discussed to define syntax for "optional" filename values, so that the same mechanism can be used for not just blame.ignoreRevsFile but other filenames. Queued just as a reminder of the theme.
