Several improvements and bugfixes:
- Big optimization of WriteableCollection.delete() (this time it DOESN'T crash IE or Edge!)
- Support for bulkPut() and bulkDelete().
- New methods on Collection: Collection.raw() and Collection.clone()
- Default console.warn() when db upgrade or deletion was blocked (overridable)
- Rigorous unit testing of CRUD hook api. Found and corrected several bugs.
- Updated typings with added methods.
Production release will come within couple of days...
