GT4Py v1.2.1

Changes since v1.2.0

General

• Update dace dependency to 2.0.0a6.
• Support PEP 695 type aliases (type X = ...) in annotations, with diagnostics that point at the offending annotation.
• Fix latent bugs surfaced by the Python 3.12 floor and stop re-exporting the deprecated typing aliases (Dict, List, Set, FrozenSet, Tuple, Type) from gt4py.eve; use the builtin generics instead.

Cartesian

• Add support for IntEnum values in stencil code and as stencil arguments.
• Allow data dimension sizes to be any integer type, not just plain int.
• Remove deprecation warnings emitted by the GTScript frontend on Python 3.12 and later.
