Dear Maintainer,

Recently I have updated pyqt5 and related packages to use sip5 instead of
sip4 for build. This is in experimental for now, but I want to upload it
to unstable in a month or two.

This change breaks PyQt5 extension ABI, so all packages build-depending on
pyqt5-dev need to build with sip5 too.

Quick migration guide:

1) Build-depend on python3-sipbuild(-dbg) and sip5-tools.

   - Inspect pyproject.toml (if it exists) for additional dependencies, maybe
     you will need also python3-pyqtbuild.

2) If your package has a project.py file, call sip-build to build it.
   For separation of configure and build phases, pass --no-make to it.

3) If your package does not have a project.py file, but has a configure.py,
   update that file to the latest version of the boilerplate (v2.16), which
   you can find in the experimental version of qscintilla2 package.

   (Qscintilla2's configure.py used to be a recommended way to build sip
   projects.)

4) If your package called /usr/bin/sip directly, call /usr/bin/sip5 instead.

5) If your package had a runtime dependency on python3-sip or ${sip3:Depends},
   depend on python3-pyqt5.sip instead. There is no analogue for dh_sip3
   helper yet.

   (Upstream now recommends each project to use its own private copy of sip.
   In Debian, I recommend you to use pyqt5's copy which is python3-pyqt5.sip).

6) If you build a -dev package with .sip files, they are now installed into
   a new location (in dist-packages). Also .toml files now should be present.

You can see what I have done in pyqt5, pyqt5chart, pyqt5webengine and
qscintilla2 packages in experimental (see the relevant commits in git).

The official documentation for sip5 is available online [1] or in sip5-doc
package. For help you can ask me or pyqt/sip mailing list [2] (subscription
needed to post messages).

Please stage your changes in experimental (or in a VCS) for now. They will
need to be uploaded to unstable together with pyqt5.

Please remove pyqwt3d. It is a leaf package and missed trixie because it
depends on the obsolete sip4. No upstream activity in years.

We believe that the bug you reported is now fixed; the following
package(s) have been removed from unstable:

   pyqwt3d |    0.1.8-6 | source
python-qwt3d-doc |    0.1.8-6 | all
python3-qwt3d-qt5 | 0.1.8-6+b5 | riscv64
python3-qwt3d-qt5 | 0.1.8-6+b9 | amd64, i386, mips64el, ppc64el, s390x
python3-qwt3d-qt5 | 0.1.8-6+b10 | arm64

------------------- Reason -------------------
RoQA; leaf pkg; depends on sip4; dead upstream
----------------------------------------------

Note that the package(s) have simply been removed from the tag
database and may (or may not) still be in the pool; this is not a bug.
The package(s) will be physically removed automatically when no suite
references them (and in the case of source, when no binary references
it).  Please also remember that the changes have been done on the
master archive and will not propagate to any mirrors until the next
dinstall run at the earliest.

Packages are usually not removed from testing by hand. Testing tracks
unstable and will automatically remove packages which were removed
from unstable when removing them from testing causes no dependency
problems. The release team can force a removal from testing if it is
really needed, please contact them if this should be the case.

We try to close bugs which have been reported against this package
automatically. But please check all old bugs, if they were closed
correctly or should have been re-assigned to another package.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 964130@bugs.debian.org.
