CHANGELOG-unreleased.md

@@ -14,6 +14,7 @@ the released changes.
 - Made `Residuals` independent of `GLSFitter` (GLS chi2 is now computed using the new function `Residuals._calc_gls_chi2()`).
 - `ssb_to_psb_ICRS` implementation is now a lot faster (uses erfa functions directly)
 - `ssb_to_psb_ECL` implementation within `AstrometryEcliptic` model is now a lot faster (uses erfa functions directly)
+- Upgraded versioneer for compatibility with Python 3.12
 ### Added
 - CHI2, CHI2R, TRES, DMRES now in postfit par files
 - Added `WaveX` model as a `DelayComponent` with Fourier amplitudes as fitted parameters
@@ -22,6 +23,8 @@ the released changes.
 - Added radial velocity methods for binary models
 - Support for wideband data in `pint.bayesian` (no correlated noise).
 - Added `DMWaveX` model (Fourier representation of DM noise)
+- Piecewise orbital model (`BinaryBTPiecewise`)
+- Simulate correlated noise using `pint.simulation` (also available via the `zima` script)
 ### Fixed
 - Wave model `validate()` can correctly use PEPOCH to assign WAVEEPOCH parameter
 - Fixed RTD by specifying theme explicitly.
