Punctuation after doi and case of backref text

[nkr0]

1. After a DOI link, incollection, inbook, or book type entries get a punctuation. Whereas, a regular article doesn't. In the screenshot, entries 2, 3, and 4 are journal articles.
2. Similarly, the backref text Cit. gets an uppercase C for the former type of entries and a lowercase c for articles.

I'm guessing this is the same issue as #141, which is resolved in the dev version of biblatex-apa here on GitHub (cf. #159). If you can share the .bib file (or at least some of the relevant entries) that was used to produce the screenshot I could verify that or see if the fix needs additional work. (Note that sharing the relevant .bib entries and an example document that lets other people reproduce the output you are getting alongside the image is always appreciated. Often it's the only way to figure out what is going wrong.)

The sample below will produce the 6 entries in the screenshot above. I had seen #141 before filing this, but I wasn't sure whether the bug in the DOI field was also included in that fix. Also, the issue with the case of backref text is new.

I am using the version from Debian testing and apa.bbx says 2021/12/24 v9.15; which seems odd because the latest tag I see here is 9.14. Anyway, #159 is from this Feb.

With the dev version (and the dev version of biblatex and Biber) the undesirable periods are all gone

So this was fixed by #159.

The different capitalisation of "cit on" was caused directly by the punctuation. The period was a sentnce-ending period after which biblatex capitalises automatically.

Ok, thanks. I'll close this issue.
