Gnu Emacs Ada mode 7.3.beta is now available in GNU ELPA devel for beta testing.

See the 7.3 Beta on the GNU ELPA Ada-mode page

Features

Ada mode provides auto-casing, fontification, navigation, and indentation for Ada source code files.

Cross-reference information output by the compiler is used to provide powerful code navigation (jump to definition, find all uses, show overriding, etc). By default, only the AdaCore GNAT compiler is
supported; other compilers can be supported. Ada mode uses gpr_query to query compiler-generated cross reference information

Ada-mode and wisi are now compatible with recent gnat versions.
The grammar is updated to the proposed Ada 2022 version.

Incremental parse is provided.
