The LyX class works now with python 3. Certain file format conversions may
still fail (convert_multiencoding() is a hot candidate), but this will need
to be fixed in the individual modules.
LyX did not distinguish compressed and uncompressed svg files previously.
Therefore XHTML export of vector graphics did use svgz images directly, which
is not supported by browsers. If svg and svgz are treated as two formats then
all works fine. This is also consistent with the loadable image formats
reported by qt: It reports both svg and svgz.
The gunzip dependency in converters is not new (it is already used internally),
but the gzip dependency is new, so it might not be available on windows.
This is not important at the moment, since we do not yet need to convert svg
to svgz, I only added the converter for completeness.
Although the fix affects only a content of a LyX note, it is
still surprising to get a dialog-window demanding creation
a new document if trying to edit the subdocument.
Now that 5mu are added on each side of : (because it is a relation), there is no need to do the same in the definition of \vcentcolon.
This is closer to what is done in mathtools.sty.
Inset-icons are auto-scaled according to their width.
This is problematic, if converted from SVG
with the bounding box set to content (ignoring the page size)
and the content is not square.
OTOH, ignoring page size is done for good reasons - we usually want just
the drawing area when inserting an image into a document.
An invisible square with fixes this problem.
Some icons had spurious invisible elements outside the page -- leading
to too small results in the PDF. These were removed.

For efficiency, we add a new flag to the buffer indicating when changes are
present. This flag is updated at each buffer update, and also when explicitly
requested via a dispatch result flag.
The old text was incorrect and came from the 2.0 release. LyX works fine if
the default python interpreter is python 3, as long as python 2 is available
as well.
Building LyX does also work with python 3, but since I did not check all
special build steps with both cmake and autotools, I kept a note about
possible problems.
The aim of the tutorial is to explain how to use LyX and not special LaTeX issues with \frontmatter, non-TeX fonts etc. Therefore the preamble should kept clean.
