2.0.0

Breaking changes

• MobX-state-tree now requires MobX 4.0 or higher
• Identifiers are now internally always normalized to strings. This also means that adding an object with an number identifier to an observable map, it should still be requested back as string. In general, we recommend to always use string based identifiers to avoid confusion.
• Due to the changes in Mobx 4.0, types.map(subType).keys() will return Iterator instead of ObservableArrays. In order to address this issue, wrap the keys with Array.from().

1.4.0

Features

• It is now possible to create custom primitive(like) types! Implements #673 through #689
• getIdentifier is now exposed as function, to get the identifier of a model instance (if any). Fixes #674 through #678 by TimHollies
• Writing middleware has slightly changed, to make it less error prone and more explicit whether a middleware chain should be aborted. For details, see #675 by Robin Fehr
• It is now possible to configure whether attached middleware should be triggered for the built-in hooks / operations. #653 by Robin Fehr
• We exposed an api to perform reflection on model instances. #649 by Robin Fehr

Fixes

• Fixed a bug where items in maps where not properly reconciled when the put operation was used. Fixed #683 and #672 through #693
• Fixed issue where trying to resolve a path would throw exceptions. Fixed #686 through #692
• In non production builds actions and views on models can now be replaced, to simplify mocking. Fixes #646 through #690
• Fixed bug where tryResolve could leave a node in a corrupt state. #668 by dnakov
• Fixed typings for TypeScript 2.7, through #667 by Javier Gonzalez
• Several improvements to error messages

1.3.1

• Fixed bug where flows didn't properly batch their next ticks properly in actions, significantly slowing processes down. Fixes #563

1.3.0

• Significantly improved the undo/redo manager. The undo manager now supports groups. See #504 by @robinfehr! See the updated docs for more details.
• Significantly improved performance, improvements of 20% could be expected, but changes of course per case. See #553
• Implemented actionLogger middleware, which logs most events for async actions
• Slightly changed the order in which life cycle hooks are fired. afterAttach will no fire first on the parent, then on the children. So, unlike afterCreate, in afterAttach one can assume in `afterAttach that the parent has completely initialized.

1.2.1

• 1.2.0 didn't seem to be released correctly...

1.2.0

• Introduced customizable reference types. See the reference and identifiers section.
• Introduced model.volatile to more easily declare and reuse volatile instance state. Volatile state can contain arbitrary data, is shallowly observable and, like props, cannot be modified without actions. See model.volatile for more details.
