Indexed DB: Replace DOMError with DOMException

DOMError has been removed from the DOM standard in favor of DOMException, and the Indexed DB draft spec has been updated to use DOMException for error attributes. The error attribute on IDBRequest and IDBTransaction will now return DOMException instances instead of DOMError instances. Both types have 'name' and 'message' properties, so code that tests properties (e.g. request.error.name) or does logging (e.g. transaction.error.message) will be unaffected. #

Deprecations and Removals

Deprecation policy

To keep the platform healthy, we sometimes remove APIs from the Web Platform which have run their course. There can be many reasons why we would remove an API, such as:

Some of these changes will have an effect on a very small number of sites. To mitigate issues ahead of time, we try to give developers advanced notice so they can make the required changes to keep their sites running.

Chrome currently has a process for deprecations and removals of API's, essentially:

You can find a list of all deprecated features on chromestatus.com using the deprecated filter and removed features by applying the removed filter. We will also try to summarize some of the changes, reasoning, and migration paths in these posts.

Remove RC4

RC4 is a 28 year old cipher that has done remarkably well, but it is now the subject of several, significant attacks. The IETF has decided that RC4 is sufficiently bad to warrant a statement that it must no longer be used (RFC 7465). When Chrome makes an HTTPS connection it has an implicit duty to do what it can to ensure that the connection is secure. At this point, the use of RC4 in an HTTPS connection is falling below that bar. #

Remove SVG glyph-orientation-horizontal and glyph-orientation-vertical

Remove SVG glyph-orientation-horizontal and glyph-orientation-vertical properties. CSS Writing Modes evolved since SVG has forked its old specification and add these properties. It now includes better alternatives for these properties, and recommend to deprecate. Since the usage of these properties are low enough that simply removing them should simplify the work for both browser developers and web developers. Web developers can now use CSS text-orientation property for SVG text. #
