Changelog

v0.9.0-rc (2019-02-22)

As we queued up quite a few changes, we're doing a release candidate first for you to test:

• Improved relations support

• Embedded structs

• Custom value-converter to store unsupported types & structs that can't be inlined/prefixed

• Recognize and handle type aliases and named types used as entity fields

• New Box methods: CountMax(), IsEmpty(), Contains() and PutAsyncWithTimeout()

• Query support AND & OR (combine conditions)

• New Query methods: Limit, Offset​

• New Query methods: Set*Params (type-based) - to run a cached query with custom parameters

• Query LT|GT|Between support for unsigned numbers

• Support numeric string ID in the entity

• Support for[]string as a field type

• Optional pass/return-by-value for slice-of-structs in the generated code

• Change strings to use hash-based instead of value-based indexes by default

• A new option to AlwaysAwaitAsync that can be enabled during initialization

v0.8.0 (2018-12-06)

• New Query API​

• Box and Query do not require manual closing anymore

• Support for renaming entities and their properties using UIDs

v0.7.1 (2018-11-30)

• Fixed wrong mapping for Go types (u)int and (u)int8. Luckily we noticed this very early: if you used those types in previous versions, please delete old database files.

• Transactions are now safely aborted in case of panics

v0.7.0 (2018-11-29)

• Changed file name of generated code, e.g. file endings for model is now ".obx.go"

• Foundation for all query conditions (final query API will come with the next version)

• Put(object) now assigns the new id to the object itself

v0.6.0 (2018-11-28)

Initial public release
