Let's start from here. I don't think it needs to be too long, just a
summary of the most awesome changes, I'd say.
Let's leave it commented out for now, until the description is finished
and ready for localization. This is the description which may appear in
software installers using appstream metadata.

Did a bit of archeology to get all the dates back.
I didn't add any description. Not sure if we should bother that much for
older versions (but most probably for upcoming version, would be
useful).
I also wanted to add URLs to the various news for each release, but
appstream-util would fail, telling that hyperlinks are not allowed
inside <p>. Unfortunately <release> tag cannot have a <url> child (nor a
property) according to appstream docs. So for now, I'll just stick to
date listing.

Replace diacritical marks, which aren't supported in the target
encoding, with equivalent precomposed characters.

Replace underscore with ampersand in mnemonics.

Current migration code would still return TRUE for success if the copy
of a regular file failed for any reason.
Also getting rid of some weird block and making sure we free dirname
only when it has been assigned a value.

When recursively browsing folders, there is always the risk of infinite
recursivity, in particular with symbolic links which can create loops.
Let's just assume that we don't have any data over 5 levels of
directories to avoid a security risk.

We now use HTTPS everywhere on the website. The link would be anyway
redirected, but we may as well write down the good link directly.

By default, autoconf only takes care of po/POTFILES, not any
po-*/POTFILES. The file contents has to go in po-*/Makefile, after
running `config-status`, step which was consequently not properly done.
And last consequence is that `make update-po` in any po-*/ was quite
broken. Now things should be better.

My bad!

Delete "paintbrush.pgm" which is binary identical to "paintbrush01.pgm",
now that we have proper migration code for gimpressionist presets.

paintbrush.pgm and paintbrush01.pgm are binary identical. If they were
brushes we ship as data, that would be more annoying because they could
be used in scripts or in various other places. But here it looks they
are used for gimpressionist plug-in only, which means they are probably
not used in some random script. All it takes is probably only to
properly migrate gimpressionist presets.
Presets using "paintbrush.pgm" will be migrated to use
"paintbrush01.pgm" instead.

In particular, I noticed that some data can be on 2 levels (or more?).
For instance gimpressionist presets were not migrated from 2.8 to 2.9
because of this.

Override get_invalidated_by_change() with the same logic as
get_required_for_output(), to avoid unnecessary invalidation.

Avoid format conversion when input and aux have the same format.

Add pass-through fast path when the ROI is completely inside/
outside the cropped rectangle.

Use bulk memcpy(), instead of per-pixel test-and-copy, in
process().

This avoids unnecessarily processing regions of the input and/or
aux nodes that will get cropped out.  In particular, this avoids
processing cropped-out regions when using the filter tool in split-
view mode.

... by making sure that the sampling thread quits before the meters
are destroyed, and before clearing the low-swap-warning idle
source.

... but disable it for now, since some of the characters are not
displayed correctly.
