BCD Metadata Changes: 41
Show all 41 changes
Note: The following represent changes to BCD metadata keys in the reported time period. Keys are not implementations, and they don't represent commitments toward implementation, etc. A new key occurring is perhaps a signal that some implementer was serious enough to add the key. Many of the features that are 'removed' are usually just 'moved' or 'renamed', but we don't have great ways to highlight that.
Backfilled entries (21)
The entries in this section saw support information change since the report on Friday, 18 July 2025, but all the supported browser versions given were more than a couple of months old. Typically, these are cases of support information being updated long after the support actually landed in a browser, but nobody ever updated the BCD entry.

New entries (20)
The entries in this section were not found in BCD on Friday, 18 July 2025, but are now present. These usually do not have any support information attached to them, and often have no corresponding MDN page. Sometimes, entries that appear here also appear in the next section (βRemoved BCD entriesβ) because of a Working Group deciding on a rename.
