## [2.0.1] 2023-03-13
Version 2.0.1 release of Bilby

This is a bugfix release after the last major update.

Users may notice changes in inferred binary neutron star masses after updating to match [lalsuite](https://git.ligo.org/lscsoft/lalsuite/-/merge_requests/1658).

### Changes
- Make sure quantities that need to be conserved between dynesty iterations are class-level attributes (!1225).
- Fix massive memory usage in post-processing calculation of SNRs (!1227).
- Update value for the solar mass (!1229).
- Make `scikit-learn` an explicit dependence of `bilby[GW]` (!1230).

## [2.0.0] 2023-02-29
Version 2.0.0 release of Bilby

This major version release has a significant change to the behaviour of the `dynesty` wrapper.

There are also a number of bugfixes and some new features in sampling and GW utilities.

### Added
- Add marginalized time reconstruction for the ROQ likelihood (!1196)
- Generate the `dynesty` posterior using rejection sampling by default (!1203)
- Add optimization for mass ratio prior peaking at equal masses (!1204)
- Add option to sample over a number of precomputed calibration curves (!1215)

### Changes
- Optimize weight calculation for `MultiBandGravitationalWaveTransient` (!1171)
- Add compatibility with pymc 5 (!1191)
- A bug fix of the stored prior when using a marginalized likelihood (!1193)
- Various bug fixes to improve the reliability of the `RelativeBinningGravitationalWaveTransient` (!1198, !1211)
- A hack fix for samplers that are not compatible with `numpy>1.23` (!1194)
- Updates to some reference noise curves (!1206, !1207)
- Fix the broken time+calibration marginalization (!1201)
- Fix a bug when reading GW frame files (!1202)
- Fix the normalization of the whitened strain attribute of `Interferometer` (!1205)
- Optimize ROQ waveform and calibration calls (!1216)
- Add different proposal distribution and MCMC length for `dynesty` (!1187, !1222)
