= 5.6 Migration Guide
|
|
:toc:
|
|
|
|
This guide discusses migration from Hibernate ORM version 5.5 to version 5.6.
|
|
|
|
For migration from other versions, see https://github.com/hibernate/hibernate-orm/wiki/Migration-Guides .
|
|
|
|
== Known changes
|
|
|
|
This version is very similar to Hibernate ORM 5.5, with the exception of having removed some long standing deprecated features.
|
|
|
|
=== Javassist removed
|
|
|
|
It is no longer an option to choose Javassist as implementation used for the bytecode enhancement of entities.
|
|
Byte Buddy has been the default for some time, and Javassist has been deprecated for some time and now has been removed.
|
|
|
|
This should have no functional impact on applications; the only exception being that it's not longer valid to
|
|
configure `hibernate.bytecode.provider=javassist`: remove the property if you're using this.
|
|
|
|
A side effect is that Hibenate ORM no longer lists javassist among its dependencies.
