Hello. You may have forgotten to update the changelog!

…8291) **Context:** Native plxpr execution was an experimental feature that was abandoned. Too much work to get rid of, but we should at least warn people about the fact we don't care about it anymore. **Description of the Change:** **Benefits:** **Possible Drawbacks:** **Related GitHub Issues:**
**Context:** We have been applying our fixture `seed` for a while, for reproducibility and CI stability. However, some newly added tests are free of seeding; hence they caused quite some unwanted stochastic failures. For example, the `test_horizontal_cartan_subalgebra.py`, who failed five times in Q3, and we are trying to seed it now. **Description of the Change:** **Benefits:** **Possible Drawbacks:** **Related GitHub Issues:** [sc-99735]
**Context:** So far we've been ignoring snapshots with `one-shot` and `tree-travsesal`, as each "snapshot" can correspond to many different states. **Description of the Change:** The recorded measurement/ state can now correspond to a list of multiple measurements, one for each time that snapshot is encountered. **Benefits:** **Possible Drawbacks:** This could balloon in size for many shots or many mcm's. But the user would just need to accept that. **Related GitHub Issues:** Fixes #8125 [sc-98188] --------- Co-authored-by: Mudit Pandey <[email protected]> Co-authored-by: Yushao Chen (Jerry) <[email protected]>
### Before submitting
Please complete the following checklist when submitting a PR:
- [x] All new features must include a unit test.
If you've fixed a bug or added code that should be tested, add a test to
the
test directory!
- [x] All new functions and code must be clearly commented and
documented.
If you do make documentation changes, make sure that the docs build and
render correctly by running `make docs`.
- [x] Ensure that the test suite passes, by running `make test`.
- [x] Add a new entry to the `doc/releases/changelog-dev.md` file,
summarizing the
change, and including a link back to the PR.
- [x] The PennyLane source code conforms to
[PEP8 standards](https://www.python.org/dev/peps/pep-0008/).
We check all of our code against [Pylint](https://www.pylint.org/).
To lint modified files, simply `pip install pylint`, and then
run `pylint pennylane/path/to/file.py`.
When all the above are checked, delete everything above the dashed
line and fill in the pull request template.

**Context:**
In some scenarios like QROM it is necessary that Select decompose using
one auxiliary qubit to control over the target operators. This new
Select decomposition achieves that.
