New indicators

• Added standardized indicators for hydrology: xclim.land.standardized_streamflow_index and xclim.land.standardized_groundwater_index. (GH/1444, PR/1877).

Bug fixes

• Fix installation instructions in the Contributing guide. (GH/2088, PR/2089).
• Fixed parameter order in typing.cast() causing intermittent errors in solar_zenith_angle calculation. (GH/2097, PR/2098).
• xclim now uses the operator standard library instead of using xarray's derived get_op function. A refactoring in xarray had changed the position of get_op which caused breakage. (GH/2113, PR/2114).
  • All other uses of xarray's internal API were also removed. (PR/2116).
• Fixed an issue with star-annotated call signatures to maintain Python 3.10 compatibility. (PR/2116).
• Fixed to_agg_units that was converting units of temperature differences prematurely, without changing the values accordingly in the related DataArrays. (GH/2121, PR/2122).
• get_calendar now supports pandas.DatetimeIndex. xclim no longer uses xarray.cftime_range, which has been deprecated. (PR/2130).
• Avoid unnecessary time resampling in xclim.indices.stats.preprocess_standardized_index when freq is not None but the same as the input data. (GH/2111, PR/2112).
• Fixed an issue with fire_season that made it fail with datasets having non-uniform chunks. (GH/2129, PR/2132).

Breaking changes

• xclim no longer supports Python 3.10. The minimum required version is now Python 3.11. (PR/2082).
  • Reverted: Extended support for Python3.10 will continue until further notice. (PR/2100).
• The minimum versions of several key dependencies have been raised (numpy >=1.24.0; scikit-learn >=1.2.0; scipy >=1.11.0). (PR/2082).
• To ensure consistent naming of converters, the following indices have been deprecated with replacements. Changes will be made permanent in xclim v0.57.0. (GH/2039, PR/2117):
  • sfcwind_2_uas_vas: Use sfcwind_to_uas_vas instead.
  • uas_vas_2_sfcwind: Use uas_vas_to_sfcwind instead.

Internal changes

• black, isort, and nbqa have all been dropped from the development dependencies. (GH/1805, PR/2082).
• ruff has been configured to provide code formatting. (PR/2083):
  • The maximum line-length is now 120 characters.
  • Docstring formatting is now enabled.
  • Line endings in files now must be Unix-compatible (LF).
• The blackdoc pre-commit hook now only examines .rst and .md files. (PR/2083).
• The xclim documentation now has a support page for detailing the project's usage and version support policies. (PR/2100).
• The indicator heat_wave_index now uses hot_spell_total_length index. The heat_wave_index index is identical to hot_spell_total_length and will be dropped in future versions. (GH/2031, PR/2102).
• Updated pre-commit hooks to their latest versions. (PR/2116).
• .. math:: tags in documentation are now properly indented with three (3) spaces. (PR/2128).
