| Upgrade Guides for Genero BDL / 2.2x upgrade guide | |
As a general rule, when upgrading to a feature release version like 2.10 to 2.20 or 2.20 to 2.21, you must recompile all your .4gl modules and .per form files. Recompilation is not required when upgrading to a new bug fix release like 2.20.01 to 2.20.02.
