MDAnalysis CHANGELOG
======================
The rules for this file:
* entries are sorted newest-first.
* summarize sets of changes - don't reproduce every git log comment here.
* don't ever delete anything.
* keep the format consistent (79 char width, M/D/Y date format) and do not
use tabs but use spaces for formatting
* accompany each entry with github issue/PR number (Issue #xyz)
* release numbers follow "Semantic Versioning" https://semver.org

Changes
* Biopython is now an optional dependency (Issue #3820, PR #4332)
* Networkx is now an optional dependency (Issue #3822).
* High memory tests (enabled through the environment variable
`ENABLE_HIGH_MEM_UNIT_TESTS` are now only enabled if the environment variable

* 2.6.0
Fixes
* Fix AtomGroup.center_of_charge(..., unwrap=True) giving
inconsistent (but scientifically correct) results on Intel macOS
(Issue #4211)

* Add definition of ts.data['time'] in LAMMPSDump Reader (Issue #3546)
* As per NEP29 the minimum supported version has been raised to 1.22. We
have opted to pin to a minimum of 1.22.3 to avoid known issues on some
platforms.
* GSD is no longer a core dependency of MDAnalysis. It must be installed
independently if you wish to read HOOMD trajectory files.

no longer tested in our continuous integration pipelines). Note: whilst
no code changes have been made to disable 32 bit, although it is known that
new versions of most MDAnalysis core dependencies no longer release
32 bit compatible versions. (Issue #3858, PR #4176)

analysis.nucleicacids' NucPairDist and WatsonCrickDist classes has been
removed. Please use the `results.pair_distances` and `times` attributes

* moved some variables (`MONATOMIC_CATION_CHARGES `and
`STANDARDIZATION_REACTIONS`) out of the related functions to allow users
fine tuning them if necessary.

charges: previously only based on the number of unpaired electrons, now
based on this and the number of heavy atom neighbors.
* use RDKit's `RunReactantInPlace` for the standardization reactions, which
should result in a significant speed improvement as we don't need to use
bespoke code to transfer atomic properties from the non-standardized mol
to the standardized one.
