What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

See the CHANGELOG .

- **changed** — When using dl_iterate_phdr to discover the plugin directory, the default compiled-in plugin directory is only overridden if dl_iterate_phdr successfully discovers the plugin directory, instead of being set to empty string on search failure
- **changed** — HTML table cells are now emitted after the table border and rules to improve Z-ordering when post-styling tables with CSS

###### Changed

- When using `dl_iterate_phdr` to discover the plugin directory, the default
  compiled-in plugin directory is only overridden if `dl_iterate_phdr`
  successfully discovers the plugin directory. Previously if the
  `dl_iterate_phdr` search failed, the plugin directory would be considered the
  empty string.
- The cells of an HTML table are now emitted _after_ the table border and rules.
  The main effect of this is, when post-styling a table with CSS, cell content
  remains visible. I.e. Z-ordering is more intuitive.
