[Release] Checkmk beta release 2.3.0b1

[Checkmk-Announcement (Checkmk Announcements)]

Dear friends of Checkmk,

Checkmk 2.3.0 beta has started with the release of 2.3.0b1!

After four weeks of internal alpha testing, we are confident enough in the current stability to progress to public beta.

New development APIs in beta

All important elements of creating your own monitoring plug-ins are covered by development APIs with Checkmk 2.3.0. Migrating plug-ins will lead to better stability and hence a better user experience for users and extension developers.
While we recommend testing the APIs and highly appreciate any feedback: Be aware that during the beta phase incompatible changes to the APIs might occur. Details can be found in werk 16259.

Things to keep in mind for Checkmk MSP

The previously called Checkmk Managed Services Edition will be called Checkmk MSP and now includes all features of Checkmk Cloud on top of the MSP features. With this comes also a mandatory license verification.
Before updating, please make sure to enter your Licensing Credentials in Setup > Maintenance > Licensing and then follow the standard procedure to first update remote sites before updating your central site.

Feedback

We would like to ask all users to try out the new version and help us ensure
that Checkmk 2.3 becomes a success.
Bugs can be reported via the the dedicated beta support portal for anyone with a Checkmk subscription directly purchased from Checkmk or via feedback-2.3-beta@checkmk.com.
Please share your feedback on the 2.3 beta experience and the new features with us by completing this survey!

This beta release ships with 890 changes affecting all editions of Checkmk,

I corrected the text:
The beta support portal is only accessible for anyone with a Checkmk subscription, which was directly bought at the Checkmk GmbH or a reseller (very specific kind of partner, likely not the one you used).
Anyone, who has bought Checkmk via a support partner (typical case), can not access this portal as we do not know who you are, but needs to ask their partner to create a ticket or use feedback-2.3-beta@checkmk.com.
