===================================== * add support for formats without separators in strptime (e.g. '20200229', issue 301). This required removing support for > 4 digit years. * set the c_api_binop_methods compiler directive to True to retain Cython 0.x behavior for arithmetic operators for Cython >= 3.0.0 (issue 271). * support for python 3.12.
1.6.2
===================================== * num2date should not fail on an empty integer array (issue 287). * longdouble keyword in date2num so that a roundtrip from a time to a date and back again does not lose microsecond precision when the units require the times be encoded as floating point values (PR 284) * added strptime method (issue 277). * cibuildwheel wheel-building workflow added to github actions by ocefpaf (triggers binary wheel builds and uploads to pypi automatically when GH release created). PR 290.
1.6.1
===================================== * fix failing tests on windows with numpy 1.23.0 (issue 278) * expose to_tuple module function in public API.
1.6.0
===================================== * fix for masked array inputs (issue 267). * improved performance of the num2date algorithm, in some cases providing an over 100x speedup (issue 269, PR270). * fix for date2index for select != 'exact' when select='exact' works (issue 272, PR273)
1.5.2
===================================== * silently change calendar='gregorian' to 'standard' internally, since 'gregorian' deprecated in CF v1.9 (issue 256). * add "is_leap_year" function (issue 259). * wheels that work on Apple M1 (arm64) available on pypi.
1.5.1.1
=============== * no code changes, just new binary wheels for python 3.10.
