Upgrade recipe 6.5

OptaPlanner’s public API classes are backwards compatible (per series), but users often also use impl classes (which are documented in the reference manual too). This upgrade recipe minimizes the pain to upgrade your code and to take advantage of the newest features in OptaPlanner 8.

Legend

Every upgrade note has an indication how likely your code will be affected by that change:

  • Major Likely to affect your code.
  • Minor Unlikely to affect your code (especially if you followed the examples), unless you have hacks.
  • Impl detail Will not affect your code, unless you have very deep hacks.
  • Recommended Not a backward incompatible change, but you probably want to do this.
  • Readme Read this to better understand why the subsequent major changes were made.

Upgrade from an older version

To upgrade from an older version, first apply the previous upgrade recipes.
