v2.2.7

Important

Previously setting entropy in your population .ini file would fail to properly create a fixed RNG seed for orbital period distributions and star formation histories other than burst. This has now been fixed.

What's Changed

• [pre-commit.ci] pre-commit autoupdate by @pre-commit-ci[bot] in #811
• [fix] Update OS matrix in install_extras.yml by @maxbriel in #806
• [fix] RNG arguments for distribution samplers by @sgossage in #822.

Full Changelog: v2.2.6...v2.2.7

POSYDON v2.2.6

Important

This fixes a critical bug in DoubleCO where the gravitational merger time was not correctly added to the binary time. The outcome of the evolution (CO_contact vs maxtime) should be correct.
This was introduced in v2.2.0.

What's Changed

• [fix] CO step solver time handling by @sgossage in #810
• [fix] Combine solver solution with time offset by @maxbriel in #809
• [chore] update POSYDON version by @maxbriel in #812

Full Changelog: v2.2.5...v2.2.6

POSYDON v2.2.5

What's Changed

🐛 Bug fixes

• [fix] Change solver interval to align with the evolution time by @maxbriel in #795
• [fix] Update package version in meta.yaml and fix unit test by @maxbriel in #804

🛠️ Enhancements

• [enhancement] Automate conda version by extracting it from setup.py by @maxbriel in #782 [reverted]

Full Changelog: v2.2.4...v2.2.5

POSYDON v2.2.4

What's Changed

🐛 Bug fixes

• [fix] Use metallicities instead of metallicity in popsyn CLI by @sgossage in #781

Note

If you are using .ini files from a prior release, ensure that the metallicity field is now renamed to metallicities in accordance with these changes to avoid errors. The default .ini file packaged with POSYDON already contains these updates.
