v0.9.0 (2019-04-24)

  • Minor refactoring/linter issues

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)

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"
