Build configuration:
- Update to C++20 standard across all platforms
- Minimum supported compiler versions for C++20 are:
- Visual Studio 2019 16.9.3 [unchanged]
- GCC 10 (Ubuntu 20)
- Clang 16 (Xcode 16.0)
Base headers synchronized with Chromium:
- Foundation: cef_immediate_crash.h, cef_always_false.h
- Compiler utilities: cef_compiler_specific.h
- Threading primitives: comments/minor fixes only
- Memory management: cef_scoped_refptr.h, cef_ref_counted.h
- WeakPtr: cef_weak_ptr.h
- Callback/Bind system: atomic update of all callback headers
New files:
- cef_is_complete.h, cef_is_instantiation.h, cef_to_address.h
- cef_always_false.h, cef_callback_tags.h
Removed unused standalone headers:
- cef_tuple.h, cef_auto_reset.h, cef_callback_list.h
- cef_cancelable_callback.h, cef_scoped_typeref_mac.h
- cef_scoped_block_mac.h, cef_scoped_policy.h
Unit tests (177 tests + 1 Windows-only):
- Ported base header tests from Chromium to ceftests/base/
- Added gmock support with fused sources
- Added test_bind.h for BindLambdaForTesting()
Documentation:
- Added CLAUDE_BASE_SYNC_INSTRUCTIONS.md for future syncs
