Reset ANNOUNCE after 2.1 release.
-GNUstep Objective-C Runtime 2.1
-=================================
+GNUstep Objective-C Runtime 2.2
+===============================
-This is the first update to the second major release of the GNUstep Objective-C
+This is the second update to the second major release of the GNUstep Objective-C
runtime (a.k.a. libobjc2). This runtime was designed to support the features
of modern dialects of Objective-C for use with GNUstep and other Objective-C
programs.
-*NOTE:* This is the first release to use submodules. If you are downloading
-the sources from git, please make sure that you do a recursive clone. If you
-forget, the build system will give you instructions to correct this.
-Tarballs from GitHub do not include submodules, so if you are downloading the
-tarball then you will need to download the submodule separately.

-
Highlights of this release include:
-- Numerous improvements to the Objective-C++ exception interoperation code.
- The runtime now dynamically detects whether the libcxxrt or libsupc++ variant
- of the Itanium C++ Exception ABI is being used
-
-- Sending a message to `super` where the corresponding method did not exist was
- silently ignored in previous versions of the runtime. This now correctly
- invokes the forwarding hooks and so (with an implementation of the Foundation
- framework, such as GNUstep Base or WinObjC) will trigger an exception or
- invoke `forwardInvocation:`.
-
-- The checks for overloaded memory management methods were incorrect, causing
- some classes to be incorrectly opted into ARC fast paths. These checks are
- now correct.
-
-- Several memory management bugs in corner cases of weak reference management
- were fixed.
-
-- The ARM assembly implementation of `objc_msgSend` now correctly restores the
- stack after calling a forwarding implementation. This bug caused stack
- corruption and usually crashing on ARM.
-
-- The ARC code has been rewritten as C++, using a well-tested third-party
- Robin-Hood hash table to store weak references, replacing the home-grown
- version. This improves performance and reduces the likelihood of bugs
- arising from the hash table implementation.
-
-- Control Flow Guard (CGF) checks were added on Windows on x86 (32- and
- 64-bit). If Objective-C code is compiled with CFG enabled then
- `objc_msgSend` will crash if it attempts to jump to an address that is not a
- valid function entry point.
-
-- The function signatures in the blocks headers were updated for compatibility
- with recent macOS releases.
-
-- Support for the C11 _Atomic type qualifier in property metadata was added.
