BETA (Dec 2022)

New features

  • New platform: macosx-armv6 (to support M1, M2)
  • New platform: linux-arm64


  • editor: Added support for once classes in feature code completion.
  • runtime and generated C code: updated C code to match clang expectations. Mostly related to clang optimization, and especially on ARM architecture.
    • Fixed code generation for equality tests when the second operand is a call to a function that can allocate memory so that the first operand gets moved by GC (reproducible when compiled with clang as C compiler).
  • wrapc: improved glue C code to support recent version of gcc.
  • dotnet: enabled the use of the emdc.exe md consumer, as an alternative to the COM md consumer.

Bug fixes

  • compiler: fixed crash when a once class lists no creation procedures.
  • studio: allow user to include ecf file that is a redirection (using the Browse button of the "Add Library" dialog)
  • editor: Fixed crash on Windows, when first inserting Unicode symbol using the Symbols dialog.
  • installation: On Windows, fixed issue preventing the EiffelStudio installations of both 32bit and 64bit versions at the same time on the same machine.
  • studio: Fixed "Add cluster" in recursive cluster, and also allow to create a new top level cluster.
  • dotnet: Fixed a bug that caused discarding a .NET namespace when saving an ECF from the project setting dialog.
