- Allow to delete all the columns in a ctable. Fixes 306.
- Double-check the value of a column that is being overwritten. Fixes
307.
- Use `pkg_resources.parse_version()` to test for version of packages.
Fixes 322.
- Now all the columns in a ctable are enforced to be a carray instance
in order to simplify the internal logic for handling columns.
- Now, the cparams are preserved during column replacement, e.g.:
`ct['f0'] = x + 1`
will continue to use the same cparams than the original column.
- C-Blosc updated to 1.11.2.
- Added a new `defaults_ctx` context so that users can select defaults
easily without changing global behaviour. For example::
with bcolz.defaults_ctx(vm="python", cparams=bcolz.cparams(clevel=0)):
cout = bcolz.eval("(x + 1) < 0")
- Fixed a crash occurring in `ctable.todataframe()` when both `columns`
and `orient='columns'` were specified. PR 311. Thanks to Peter
Quackenbush.
