  • ⚠️ Huge performance improvements of the entt::any class due to large internal changes with no impact on the API
  • Deprecate basic_any<...>::type() in favor of basic_any<...>::info()
  • Make stripped_type_name return empty views if name is not available
  • Add a full_type_name function to type info API
  • Break the dependency between basic_hashed_string and string_view
  • Make const char * conversion operator explicit for basic_hashed_string
  • Add typed data overloads to basic_any<...>
  • Add has_value overloads to basic_any<...>
  • Make basic_any support self-assignment smoothly

• container:

  • Transparent lookup for dense_map<...>::at

• entity:

  • Deprecate basic_sparse_set<...>::type() in favor of basic_sparse_set<...>::info()
  • Full support to swap-only policies for runtime views
  • A const registry is no longer a sync point for the basic_organizer class
  • Make it possible to clear() the registry context as needed
  • Support swapping entity storage objects
  • Quit accepting (and silently discarding) arguments for empty types when invoking ::emplace on a storage
  • Quit accepting (and silently discarding) arguments for empty types when invoking ::insert on a storage

• graph:

  • Make the graph method of the organizer class const as it should be

• meta:

  • ⚠️ Huge performance improvements overall due to large internal changes with no impact on the API
  • Introduce meta_dynamic_extent for meta sequence containers
  • Deprecate basic_meta_sequence_container_traits::fixed_size in favor of basic_meta_sequence_container_traits::extent
  • Expose the element type in the factory API
  • Built-in name support for meta types, data and functions
  • Forward declared meta_factory and meta_ctx as it should be
  • Drop meta destructors support for perf reasons
  • Break safe-mode when uninitialized for meta data and meta func
  • Remove operator== and operator!= for meta_handle
  • Strip context-only and context-aware copy constructors from meta_handle
  • Make meta_any support self-assignment smoothly
  • Make as_is_t policy match the constness of the returned type, if any
  • Introduce as_value_t policy to force a copy of the returned value (default)
  • Allow top-level only searches for meta data and meta functions
  • Deprecate const meta_handle::operator->

• poly:

  • Deprecate basic_poly<...>::type() in favor of basic_poly<...>::info()

• process:

  • ⚠️ Complete redesign of the module

• signal

  • Make delegate tests work in release mode (disable comdat folding)

• tools:

  • Introduce davey, an ImGUI based viewer for entities and components (work in progress)

Build system

• Updated IWYU version
• Prepared workflow and build system for testbed target
• Renamed tools.yml to analyzer.yml
• Natvis files are now part of the source tree
• Install natvis files along with source files if requested

Any other business

• Removed all previously deprecated methods

Natvis support

All natvis files have been updated where necessary.

Breaking changes

• core:

  • Deprecated basic_any<...>::type(), use basic_any<...>::info() instea0d
  • const char * conversion operator is now explicit for basic_hashed_string

• entity:

  • Deprecated basic_sparse_set<...>::type(), use basic_sparse_set<...>::info() instead
  • Arguments are no longer accepted when invoking ::emplace on a storage for empty types
  • Arguments are no longer accepted when invoking ::insert on a storage for empty types

• meta:

  • Deprecated basic_meta_sequence_container_traits::fixed_size, use basic_meta_sequence_container_traits::extent instead
  • Meta destructors are no longer available for perf reasons, use C++ type destructors as it should be instead
  • Meta data and functions are no longer safe to use when uninitialized, check for validity before doing so
  • Removed operator== and operator!= for meta_handle, compare underlying objects instead
  • Removed context-only and context-aware copy constructors from meta_handle because they should not exist
  • Renamed policy as_is_t to as_value_t, as_is_t still exists but it has a different meaning and behavior now
  • Deprecated const meta_handle::operator->, use non-const handles as it should be

• poly:

  • Deprecated basic_poly<...>::type(), use basic_poly<...>::info() instead

• process:

  • ⚠️ Complete redesign of the module

Any other business

The documentation is up-to-date and the library is battle-tested with 100% coverage as usual.
