    • Support for free and member noexcept functions to the delegate class

Build system

  • Avoid installing include/BUILD.bazel
  • Updated IWYU version

Any other business

  • Removed all previously deprecated methods
  • Shared types in the test suite to avoid duplication
  • Full review to reduce NOLINT directives as much as possible
  • Refine linter configuration and address as many warnings as possible
  • Updated IWYU entt.imp as needed
  • Drop support to Android NDK r17
  • Drop support to MSVC toolset v141

Natvis support

All natvis files have been updated where necessary. New entries:

  • Natvis view for basic_handle class
  • Natvis view for meta_ctx class
  • Natvis view for meta_type_descriptor class
  • Natvis view for meta_custom_node class

Breaking changes

  • Sparse set scoped iterators are no longer a thing, check the deletion policy and use the free list value as needed instead
  • Registry traits_type is private, use entt_traits class and entity_type type member instead
  • Sparse set traits_type is private, use entt_traits class and entity_type type member instead
  • Storage traits_type is private, use component_traits class and value_type type member instead
  • The basic_observer class doesn't accept anymore a Mask template parameter
  • Renamed is_power_of_two to has_single_bit and moved it to bit.hpp
  • Removed support to empty each callbacks for single non-empty type views
  • Deprecate meta properties, use the new custom data support for meta types, data and functions instead
  • basic_sparse_set doesn't require anymore to wrap objects with anys when passing them to bind
  • The observer class is now deprecated, use the reactive mixin and storage instead

Any other business

The documentation is up-to-date and the library is battle-tested with 100% coverage as usual.
I started a long term process to reduce the number of instantiations and also speed up the compilation.
This release contains some changes in this regard. Still a work in progress though.
