Last version tested on 7.0
Our last 7.0 sandbox was recently shut down. For this reason, this will be the last version tested on 7.0 (SAP_BASIS 700 SP27 to be precise).
According to SAP Note 1648480, SAP currently plans to support the ABAP stack of SAP Netweaver 7.0 until 2025 at least. Therefore, the current version is "frozen" via a GitHub release, just in case anyone might still need it.
Now testing on 7.31
The backwards compatibility of future versions will be tested on 7.31 since this is our oldest release now. New versions MIGHT(!) run on 7.0 as well, but we won't be able to test this because we don't run suitable test systems anymore.
