[minutes, 04 Aug 2017 telcon](https://github.com/w3c/csswg-drafts/issues/1391#issuecomment-320215251) ## Changes * Three features were deferred to Level 4. These were all listed as "at-risk" in the Candidate Recommendation. A fourth feature was marked as "at-risk" but has been retained. * A Privacy and Security Considerations section was added, the contents of which say 'This specification introduces no new privacy leaks, or security considerations beyond "implement it correctly".' This is not a substantive change. * [Issue 1391](https://github.com/w3c/csswg-drafts/issues/1391) was a substantive change [Changes since the December 2015 CR](https://drafts.csswg.org/css-writing-modes-3/#changes-201512) ## Requirements satisfied (no formal requirements document) This specification helps meet requirements listed in [Requirements for Japanese Text Layout](https://www.w3.org/TR/jlreq/) in particular section "2.3 Vertical Writing Mode and Horizontal Writing Mode". It also meets requirements listed in an (early ED of) [Text Layout Requirements for the Arabic Script](https://w3c.github.io/alreq/) in particular section "2.3 Direction". The number 2.3 has no numerological significance here. ## Dependencies met (or not) The following normative references are not yet at CR: * CSS Display Module Level 3 * CSS Inline Layout Module Level 3 * CSS Overflow Module Level 3 * CSS Positioned Layout Module Level 3 * CSS Ruby Layout Module Level 1 * CSS Text Module Level 3 * Cascading Style Sheets Level 2 Revision 2 (CSS 2.2) Specification * CSS Intrinsic & Extrinsic Sizing Module Level 3 * CSS Paged Media Module Level 3 These are primarily to link to the latest definitions of each term. ## Wide Review The specification has been reviewed in depth by the I18N Core Working group. Internationalization has published the following articles which explain how to use CSS Writing Modes 3. * [Styling vertical Chinese, Japanese, Korean and Mongolian text](https://www.w3.org/International/articles/vertical-text/) * [CSS and International Text](https://www.w3.org/International/articles/css3-text/index) ## Issues addressed The [Disposition of Comments](https://drafts.csswg.org/css-writing-modes-3/issues-cr-2015) :boom: or is it this one [Disposition of Comments on GH](https://github.com/w3c/csswg-drafts/issues?utf8=%E2%9C%93&q=is%3Aissue%20label%3Acss-writing-modes-3%20) Of the 23 issues raised, 12 were accepted. Three were rejected, and the commenter indicated they were satisfied. Three comments were invalid. One, calling for a Japanese translation of the specification to be linked, was rejected as out of scope (translations may be provided by third parties of W3C Recommendations, following the usual procedure). ## Formal Objections None ## Implementation The specification is [widely implemented](http://caniuse.com/#feat=css-writing-mode), although Safari on OSX and iOS still uses a -webkit- prefix. We would expect Apple to support the unprefixed property once Writing Modes progresses to W3C Recommendation. The [testsuite](https://test.csswg.org/harness/results/css-writing-modes-3_dev/grouped/filter/1/) shows that 985 of 1143 required tests meet CR exit criteria, and 8 of 17 optional tests meet CR exit criteria. An [analysis of the test results](https://drafts.csswg.org/css-writing-modes-3/implementation-report.html) is also available :boom: the tests for features moved to Level 4 are still marked as level 3 tests, so need to be edited to make them Level 4 tests during the CR period ## Patent disclosures [none](https://www.w3.org/2004/01/pp-impl/32061/status)
