The usual version bump and changelog for the version, nothing special.

refs #10338

Only two bugfixes? I'd include at least one more from https://github.com/Icinga/icinga2/pulls?q=is%3Apr+label%3A%22consider+backporting%22+is%3Aclosed+milestone%3A2.15.0

Yes, I prefer getting a quick regression fix out for #10330 rather than spending too much time going over other PRs that don't seem too important.

I'd include at least one more

Just so that there are three instead of two? At least that doesn't sound like you'd think any one of them is particularly important.

I've additionally included #10339 because that's a fix that I understood quickly and seems to be properly tested by the unit tests.

Only two bugfixes in a non-security release look a bit too few to me.

(Please could you formulate guesses about what I meant but didn't write as questions in the future?)

Actually, I wanted you to have the freedom to choose. After all, different people consider different stuff more/less important.

other PRs that don't seem too important.

• The bug fixed by Don't set Notification#no_more_notifications on custom notifications #7818 is indeed annoying, but tolerate-able
• The bug fixed by OpenTsdbWriter#CheckResultHandler(): skip custom tags with empty values #7928 could theoretically be worked around via default template, but I'm not sure
• The bug fixed by Reset all signal handlers of child processes #8011 however breaks check plugins – we're Icinga, we should enable people to use check plugins

Primarily, it's a release to fix a regression in 2.14.4, so it would also be totally fine if it just included #10337 and nothing else.
