Is there already a schedule for 3.6? We have integrated deegre's OGCFrontController servlet into our Spring Boot 2.7.x application. Spring Boot 2.7.x is going eol end of November 2023. The successor requires Java 17, which comes with all that javax prefix stuff being replaced, which inevitably breaks our Spring Boot / deegre bridge.

We are aware of the Spring project dropping support for older versions of Java and we know that users are using Spring Boot and deegree within the same project. It is therefore our intention to release a Java 17 compatible version of deegree as soon as possible.

During the code sprint 30th Nov till 1st Dec 2023 we worked on the following issues:

• Add support for JAXB3 or higher #1569
• Migration of javax.* dependencies to jakarta.*
• Branch 3.5-main was created (bugfix line for 3.5)
• on branch main(target version 3.6) we merged:
  • PR Change dependencies to Jakarta EE libraries #1605 with commit 1fbb503 we started the 3.6 line using JAXB 4.0 and related libraries of Jakarta EE 10

The main branch has been set to version 3.6.0-SNAPSHOT, see PR #1621.

Thanks for your work on this library.

I was wondering if there's an expected release date for 3.6.0 yet, or perhaps an approximate timeline (days, weeks, months)?

[copierrj]

Status update: we're still actively reworking (upgrading and/or removing) our dependencies in order to become fully Java 17 / Tomcat 10 compatible. Most of the work has been done already (= merged into the main branch) and we are planning to have a working milestone release in a couple of weeks.
