Thanks!

Couple very minor issues:

• add the new functions to api.rst (we forgot it in all other PRs :))
• …and to the changelog
• split the test of add_log_level into two please; one normal case and one alias. I try to test only one case per test.
• please test the return values of the functions, not the side-effect on the passed in event_dict (you don’t have to keep it around either)

Thanks again!

oops sorry i overlooked it in the first round: this is implicitly tested in the next line, let’s keep it simple

[wbolster]

I've removed it. Though it will fail with a KeyError instead of an AssertionError if the test fails. But I agree, simpler is better. (Hence my combined "alias" test, btw.)

[hynek]

one more quick thing: I thing the changelog should refer the PR that actually got merged (i.e. 44) not a related issue.

Thanks again, will merge afterwards!
