version v1.0.0rc1

version v1.0.0rc1 is the official release candidate for mesmer v1.0.0. It restructures much of the code base to be more modular, flexible and stable. Mesmer now fully relies on xarray data structures, including xr.DataTree. As a consequence, mesmer now needs xarray >= 2025.03. We integrated MESMER-M, allowing the users to now emulate monthly temperatures, and MESMER-X, which enables emulation of any climate variable using conditional distributions. This version introduces support of python 3.13 and dropping support of python 3.9 and 3.10.

version 0.10.0

version 0.10.0 fixes the bug in the legacy calibration and is thus not numerically backward compatible. It also updated the supported python, pandas and xarray versions. Updating the pandas version will create an error when trying to load pickled mesmer bundles, requiring to use mesmer version v0.9.0 for this.

Full Changelog: v0.9.0...v0.10.0

version 0.9.0

version 0.9.0 is a big step towards rewriting mesmer. All statistical functionality was extracted and works for xarray data objects. It also contains data handling functions to prepare climate model data using xarray.

• The restructured code is fully functional and can be used to calibrate and emulate temperature. However, it is still missing wrappers to which encapsulates the full chain and helpers to simplify calibrating several scenarios and ensemble members.

• This version still contains the legacy routines to train and emulate temperature. It should have no numerical changes, only minimal changes in usage and offers speed gains compared to v0.8.3.
