v0.9.2

Documentation: http://bumps.readthedocs.org

Release notes: https://github.com/bumps/bumps

v0.9.2 2024-03-05

• added testing for python 3.12
• fixed issue with matplotlib >= 3.8.0 (see #129)
• added missing documents to dream manual
  (Convergence tests, Parallel coordinates plot)
• added numba.njit-accelerated fallback bounds.apply methods to dream
  (still uses compiled C DLL if available)
• provide MAX_CORR attribute on the CorrelationView; clear the figure
  if the number of variables exceeds MAX_CORR

Unstable

A persistent prerelease where build artifacts for the current tip will be deposited

v0.8.0

Documentation: http://bumps.readthedocs.org

Release notes: https://github.com/bumps/bumps

v0.8.0 2020-12-16

• add stopping conditions to DREAM, using --alpha=p-value to reject convergence
• require --overwrite or --resume when reusing a store directory
• enable outlier trimming in DREAM with --outliers=iqr
• add fitted slope and loglikelihood distribution to the loglikelihood plot
• display seed value used for fit so it can be rerun with --seed
• save MCMC files using gzip
• remove R stat from saved state
• restore --pars option, which was broken in 0.7.17
• terminate the MPI session when the fit is complete instead of waiting for the
  allocation to expire
• allow a series of fits in the same MPI session
• support newest matplotlib

v0.7.18

Documentation: http://bumps.readthedocs.org

Release notes: https://github.com/bumps/bumps

v0.7.17 2020-11-06

• restore DREAM fitter efficiency (it should now require fewer burn-in steps)
