📢 Announcements#

  1. @bjlittle migrated the SciTools social community from X (formally Twitter) to Bluesky 🦋. (PR #6237)

✨ Features#

  1. @trexfeathers and @ukmo-ccbunney extended the iris.loading.LOAD_PROBLEMS capturing to _all_ NetCDF objects that are added to a Cube during loading, as well as a selection of other objects such as CoordSystem. Note this includes an improvement to how DimCoord is ‘gracefully’ converted to AuxCoord if it is masked - the mask is now preserved when it was not previously.

🐛 Bugs Fixed#

  1. @HGWright added a new warning to inform users that the boolean coordinate generated by iris.coord_categorisation.add_season_membership() is not saveable to netcdf. (PR #6305)

  2. @bouweandela changed the convert_units method on cubes and coordinates so it also converts the values of the attributes "actual_range", "valid_max", "valid_min", and "valid_range". (PR #6416)

  3. @ukmo-ccbunney fixed loading and merging of masked data in scalar AuxCoords. (Issue #3584, PR #6468)

  4. @stephenworsley fixed the html representation of cubes in Jupyter when coordinates share the same name. (PR #6476)
