APA has simplified in-text citations in regards to multiple authors. If there is one or two authors, list their names:
(Smith, 2019); (Smith & Jones, 2019)
For three or more authors, list only the first author's name and then et al.
(Smith et al., 2019)
In the opposite direction, APA now requires listing up to 20 authors for a source in the references list. This is a change from 8 in the 6th edition. For works with more than 20 authors, list the first 19, insert an ellipsis point, and then list the last author's name.
Smith, J., Jones, B. E., Brown, K. E., Doe, J., Chan, L., Garcia, S. M., White, C-G., Fernández, J., Ahmed, A. J., Zhào, L., Cohen, D., Watanabe, K., Kim, K., Del Rosario, J., Yilmaz, P. K., Nguyễn, T., Wilson, T. H., Wang, W., Kahale, A. ... Zhang, Z. Z. (Date). Title. Source.
For books, no longer list the publication location.

If a book has a DOI assigned to it, add it to the end of the reference.

eBooks should be cited exactly as print books. Do not include a database.
Keating, D. P. (Ed.). (2010). Nature and nurture in early child development. Cambridge University Press.
Sacred texts should now be included in the references list (the 6th edition only required an in-text citation).

King James Bible. (2017). King James Bible Online. https://www.kingjamesbibleonline.org/ (Original work published 1769)
Always include the issue number. Previously if the issues were paginated continuously you did not need to include it. The formatting of the DOI should now follow the format https://doi.org/XXXXXX

If a journal article does not have a DOI, you may end the citation after the page numbers. There is no longer a requirement to include the URL of the journal's homepage. However, if an article is open access, you may choose to link directly to the article's full text.

If a magazine or news site does not have an associated daily/weekly publication, use the guidelines for a webpage. Examples include CNN and the Huffington Post.
If a library database contains its own, proprietary information that cannot be retrieved elsewhere (like Cochrane, A to Z the World, and CQ Researcher), include the name of the database and a permalink in the reference.

APA now clarifies that if the audience for the paper being written can access materials that may be in an LMS or intranet, these can be included in the references list. Previously, these were considered non-retrievable sources and were to be cited as personal communication.
