Open Source Support for Spring Boot 2.6.x ends 2022-11-24.

Open Source Support for Spring Boot 2.7.x ends 2023-05-18.

Morning Glory R2 2022 public release will be on 2022-08-08.

Nolana R3 2022 public release will be around 2022-12.

Orchid R1 2023 public release will be around 2023-04.

The support period for Morning Glory security fixed ends on Orchid public release.

Therefore Spring Boot 2.6.x cannot be used for Morning Glory because Spring Boot support ends during the support period of Morning Glory.

For Morning Glory Spring Boot 2.7.x needs to be used so that we get security fixes during the complete support period.

The same for other Spring libraries.
