# 2.0.0-dev
|
||||
* Restored all old PostgreSQL-specific annotations. Rather than a smart runtime,
|
||||
having a codegen capable of building ORM's for multiple databases can potentially
|
||||
provide a very fast ORM for everyone.
|
||||
|
||||
# 1.0.0-alpha+11
|
||||
* Removed PostgreSQL-specific functionality, so that the ORM can ultimately
|
||||
target all services.
