After consulting other colleagues, I'm proposing this revised version. Does that look ok to you? As it was simpler I've created a new commit with a Co-authored-by line, but can easily change that if you prefer.

New Languages and Language specific improvements

- +

Ada

+ +
    +
  • New implementation-defined aspects and pragmas: +
      +
    • Local_Restrictions, + which specifies that a particular subprogram does not violate one or more + local restrictions, nor can it call a subprogram that is not subject to + the same requirements.
      • +
    • User_Aspect_Definition + and User_Aspect, + which provide a mechanism for avoiding textual duplication if some set of + aspect specifications is needed in multiple places.
      • +
    +
    • +
  • New implementation-defined aspects and pragmas for verification of the + SPARK 2014 subset of Ada: +
      +
    • Always_Terminates, + which provides a condition for a subprogram to necessarily complete + (either return normally or raise an exception).
      • +
    • Ghost_Predicate, + which introduces a subtype predicate that can reference Ghost entities. +
      • +
    • Exceptional_Cases, + which lists exceptions that might be propagated by the subprogram with + side effects in the context of its precondition and associates them with a + specific postcondition. +
      • +
    • Side_Effects, + which indicates that a function should be handled like a procedure with + respect to parameter modes, Global contract, exceptional contract and + termination: it may have output parameters, write global variables, raise + exceptions and not terminate.
      • +
    +
    • +
  • The new attributes and contracts have been applied to the relevant parts + of the Ada runtime library, which has been subsequently proven to be correct + with SPARK 2014.
    • +
  • Initial support for the + CHERI + architecture.
    • +
  • Support for the LoongArch architecture.
    • +
  • Support for vxWorks 7 Cert RTP has been removed.
    • +
  • Additional hardening improvements. For more information reltated to + hardening options, refer to + the GCC + Instrumentation Options and + the GNAT + Reference Manual, Security and Hardening Features. +
    • +
  • Improve style checking for redundant parentheses + with -gnatyz
    • +
  • New + switch -gnateH + to force reverse Bit_Order threshold to 64.
    • +
  • Experimental features: +
      Storage + Model: this feature proposes to redesign the concepts of Storage Pools + into a more efficient model allowing higher performances and easier + integration with low footprint embedded run-times.
    + +
    • +
  • Bug fixes, refactorization and streamlining of the finalization machinery + for declared objects.
    • +
  • Further clean up and improvements to the GNAT code.
