Aside from a number of minor improvements and fixes to various pages, the notable changes in man-pages-3.52 are the following:
- Various pages that formerly lacked the information now have a note under RETURN VALUE that errno is set on error.
- Peng Haitao has submitted patches to around 50 pages that note functions that are thread-safe or thread-unsafe. For this purpose, the man-pages add a new section, ATTRIBUTES, as described in the man-pages(7) manual page. Peng Haitao's substantial work is ongoing, and more pages will add this information in the future.
