features/clear-site-data.yml.dist


 status:
-  baseline: low
+  baseline: high


This should not advance and should probably regress. I've sent mdn/browser-compat-data#29333 upstream. I'll freeze this status and file an issue before merging.

Agreed. Bug https://issues.chromium.org/issues/364634040 feels serious and should hold the feature back.

A bunch of features are advancing statuses in this upgrade. Here's a summary:

low to high:

clear-site-data (source, dist) (⚠️ likely dubious, see Bump @mdn/browser-compat-data from 7.3.7 to 7.3.8 #3881 (comment) ⚠️ )
contain-intrinsic-size (source, dist)
counter-style (source, dist)
device-orientation-events (source, dist)
hyphenate-character (source, dist)
hyphens (source, dist)
image-set (source, dist)
modulepreload (source, dist)
overflow (source, dist)
storage-manager (source, dist)
subgrid (source, dist)
update (source, dist)

false to low

text-indent-each-line (source, dist)
text-indent-hanging (source, dist)

I'm OK with the large number of features progressing from baseline low to high. These features match what I see at https://developer.apple.com/documentation/safari-release-notes/safari-17-release-notes.

features/absolute-positioning.yml.dist

  # support:

  #   chrome_android: "122"
  #   edge: "122"

  - css.properties.align-self.position_absolute_context
  - css.properties.justify-self.position_absolute_context
  - css.properties.place-self.position_absolute_context


See #2947, which I need to review and approve. These keys will soon go out of this feature, which is a good thing.

features/counter-style.yml.dist

  # baseline: false
  # support:
  #   safari: "17"
  #   safari_ios: "17"
  - css.at-rules.counter-style.symbols


Out of scope for this PR, but Safari is the only browser to support images as symbols. Other browsers only support text/ident symbols. It would be great to mint a new feature just for image counter styles. I guess that would require a sub-feature in BCD.

Sent mdn/browser-compat-data#29344 upstream.

captainbrosset · 2026-03-25T07:58:56Z

features/image-set.yml.dist


 status:
-  baseline: low
+  baseline: high


Found something a bit surprising in BCD:

safari: [ { "version_added": "17" }, { "prefix": "-webkit-", "version_added": "17" } ... ]

How come both prefixed and unprefixed versions of this function were added in Safari 17?
