MetPy 1.0 Release Candidate 2 has been released. The biggest change is that now XArray DataArrays can be returned from most calculations when they are passed as inputs (this may break some code not expecting this behavior). This is the final planned release candidate before the full 1.0 release (planned in about a month), so any testing and feedback is appreciated, especially in the DataArray support. We should also have a 1.0 upgrade guide available soon in the documentation.
The Unidata THREDDS Development Team released updated versions of the THREDDS Data Server (TDS) and netCDF-Java/Common Data Model (CDM) library on June 17, 2020. In addition to feature enhancements, these releases contain a variety of updates to third-party libraries, including security updates. They also address a problem in previous versions that could lead to data returned by some NetcdfSubsetService (NCSS) requests being corrupted. While the circumstances under which the problem occurs are very specific (and rare), because the possibility of data corruption exists the development team strongly recommends these upgrades to anyone using netCDF-Java/CDM or TDS. TDS administrators who are not able to upgrade immediately should disable the NetcdfSubsetService until it is possible to do so.
Netcdf-Java version 5.3.2 is now available, and includes several bug fixes, 3rd party dependency updates, and more steps towards the creation of a public API, as well as new capability for reading CDM datasets stored in any AWS S3 API compatible object store.
MetPy 0.12.0 has been released with several features and fixes, including METAR decoding and mixed-layer CAPE calculation. This is the first release that only supports Python 3.
