========================= Introduces new BufferDicts that are mostly but not completely compatible with the old. The incompatible differences are in obscure features that were mostly unused.
- BufferDicts reimplemented to give them more conventional/consistent dictionary behavior. Also have added functionality to support (limited) non-Gaussian distributions. Better documentation for BufferDicts.
- Internal data type ExtendedDict is now gone because BufferDict can provide the needed functionality in a much more robust (and simple) fashion.
8.5.1
Not secure
======================== Very minor fixes.
- Small improvement to gvar.chi2(...).
- Default svdcut changed to 1e-12 everywhere.
8.5
Not secure
====================== Very minor enhancement.
- gvar.linalg.lstsq now supports both weighted and unweighted least squares for solving a x = b when b has a covariance matrix.
8.4
Not secure
======================
- New functions eigh, svd, lstsq added to gvar.linalg. Also have a faster version of solve.
- gvar.load and gvar.dump now work with yaml as well as with pickle and json.
8.3.7
Not secure
======================== Bug fixes.
- Bug fix in evalcov_blocks() that affects some Windows installations (mismatched integer types in cython code).
- Bug fix for ode to deal with 0(0)/0(0) fringe case.
- Minor documentation fixes.
- Bug fix in GVar.__richcmp__ for Python 2.7 on macOS 10.13.5.
- Default svdcut=1e-15 added to raniter. Having a small non-zero svdcut is standard elsewhere in code.
- Improved handling of cython in makefile.
8.3.6
Not secure
============================ Minor update to keep up with changes in numpy.
