The **Simplicité platform** version **4.0 P24 BETA** will be made available on the template’s `prerelease` Git branch and as the `beta` Docker image on **wednesday Sept. 24** night. Please prepare your pre-release test instances for this upgrade by reading the [the draft release note](https://docs.simplicite.io/4.0/releasenote/releasenote-patchlevel-24.md). This future release include compatibility-breaking changes. The most significant change is the required **(Open)JDK 12** if you want to benefit from all included third party libraries (some of them are no longer compatible with JDK 8). A “light” variant of this future release will remain compatible with JDK 8 but with some third party libraries removed. See the release note for details. Any feedback is warmly welcome. ---
