0.14.2

  • Add Join-able entries API to Storage (#518)
  • Several docs / meta improvements (#526, #527, #528, #530, #531)
  • Fix bug when re-killing Entity after atomic killing followed by alloc (#533)
  • Add Storage::count and Storage::is_empty (#534)

0.14.1

  • Allow accessing the EntitiesRes fetched by a Storage (#515)
  • Book / API doc improvements (#496, #507, #511)

0.14.0

  • Changed ConvertSaveload::convert_into and ConvertSaveload::convert_from (#504)

0.13.0

This release can be skipped; please use 0.14 instead.

  • Generation now internally uses the new NonZeroI32 from nonzero_signed, meaning Option<Entity> is the same size as Entity. Note this bumps the minimum supported rust version to 1.28.0 (#447).
  • Improved saveload and added custom derive for components with Entity (#460)
  • Removed world::Bundle (#486, #505)
  • Updated Chapter 7: Setup to be more explicit, updated examples to follow that methodology (#487)
  • Added some comments to the saveload example (#492)
  • Updated dependency versions (#494)
  • FlaggedStorage rewrite with single event channel instead of multiple for ordering. (#489)
  • Make it possible to run on wasm (#495)

0.12.3

  • Add MaybeJoin to iterate over components without filtering the joint set (#455)
  • Implement Join on Fetch/Read/Write/etc. to eliminate unnecessary dereference (#472)

0.12.2

  • Fix Allocator::kill in the case of atomically created entities. (#454)

0.12.1

  • Add #[must_use] to entity builders to avoid people forgetting to call .build(). (#443)

0.12.0

  • Join::open() and Storage::unprotected_storage_mut() have been marked unsafe. Thanks to @andrewhickman for discovering this unsoundness!
  • Add common Builder trait to EntityBuilder and LazyBuilder (#426)
  • Add common MarkedBuilder trait to EntityBuilder and LazyBuilder (#426)
  • Add LazyUpdate::exec_mut which allows adding a resource from a system (#433)
  • Add build_entity() to EntitiesRes so you can use builder syntax in a system.
  • Add marked() to LazyBuilder to keep parity with EntityBuilder (#420)
  • Fix U64MarkerAllocator's internal index not being updated on saveload::DeserializeComponents (#420)

0.11.2

  • Add unprotected_storage() and unprotected_storage_mut() methods to Storage (#419)

0.11.1

  • Add diagrams to book, small code fixes in the book (#412, #416, #417)
  • Increase tuple size for SerializeComponents / DeserializeComponents (#415)

0.11.0

  • Improve docs, book and examples (#278, #281, #283, #285, #296, #313, #316, #322, #350, #356, #363)
  • Add StorageEntry for easier handling of inserting/removing component (#274)
  • Add EntityBuilder::marked convenience method (#287)
  • Add saveload module for easy entity serialization (#275, #337)
  • Add nightly feature flag for unstable features. (#290)
  • Add TrackedStorage, a more ergonomic variant to FlaggedStorage (#291)
  • Exclusive/mutable aliasing for getting an EntityBuilder to prevent unsafety. (#294)
  • Add Bundle for registering multiple resources and components at once. (#296)
  • Add get() method to Join for retrieving a single entities component in bulk. (#299)
  • Implementations of Join for owned BitSets, including AtomicBitset. (#303)
  • Remove FlaggedStorage (new storage uses the same name) and TrackedStorage in favor of the new Tracked api. (#305)
  • Add prelude module for commonly used structures and traits. (#305)
  • Add LazyBuilder for easier entity construction in systems. (#320)
  • Replace Entry with PairedStorage to prevent runtime checks for RestrictedStorage. (#324)
  • Deprecate check() which hides a possibly expensive clone. (#326)
  • Add ChangeSet for easy application to components. (#344)
  • Use criterion.rs for benchmarks (#348)
  • Update to rayon 1.0 (#352)
  • Add World::system_data method (#369)
  • BREAKING: Change the way resources are handled (see below) (shred#77)
  • Export all items currently in prelude in the root of the crate (#394)
  • If an EntityBuilder drops before being built the entity will now be deleted on maintain (#394)
  • Removed some redundancy in documentation (#394)

There is one bigger breaking change in this release. Almost allFetch / FetchMut types need to be replaced with Read / Write. Both require the resource to implement Default, because now the resources can be added to the world automatically. If you want to make the resource optional and you don't have a sensible default, Option<Read> / Option<Write> can be used. If you absolutely need the resource and it doesn't work without, use ReadExpect which will panic in case the resource does not exist (that's the same behavior as before).
