After the big security fix push, I've had a bit of a vacation. Several new
features have also landed in git-annex though.

git-worktree support is a feature I'm fairly excited by.
It turned out to be possible to make git-annex just work in working trees
set up by `git worktree`, and they share the same object files. So,
if you need several checkouts of a repository for whatever reason,
this makes it really efficient to do. It's much better than the old
method of using `git clone --shared`.

A new `--accessedwithin` option matches files whose content was accessed
within a given amount of time. (Using the atime.) Of course it can
be combined with other options, for example
`git annex move --to archive --not --accessedwithin=30d`  
There are a few open requests for other new file matching options that I
hope to get to soon.

A small configuration addition of remote.name.annex-speculate-present
to make git-annex try to get content from a remote even if its records
don't indicate the remote contains the content allows setting up an interesting
kind of [local cache of annexed files](https://git-annex.branchable.com/tips/local_caching_of_annexed_files/)
which can even be shared between unrelated git-annex repositories, with
inter-repository deduplication. 

I suspect that remote.name.annex-speculate-present may also have other
uses. It warps git-annex's behavior in a small but fundamental way which
could let it fit into new places. Will be interesting to see.

There's also a annex.commitmessage config, which I am much less excited by,
but enough people have asked for it over the years.

Also fixed a howler of a bug today: In -J mode, remotes were sorted not
by cost, but by UUID! How did that not get noticed for 2 years?

Much of this work was sponsored by NSF-funded DataLad project at Dartmouth
Colledge, as has been the case for the past 4 years. All told they've
funded over 1000 hours of work on git-annex. This is the last month of that
funding.
