While major updates (COLR v1) have been discussed and implemented in both OT and OFF texts, there are many additional changes that introduced text updates that go beyond merely editorial changes. Some parts of the OT spec were subjected to restructuring that, although they did not introduce technical changes, caused significant deviation in the language of the current OT chapters and OFF text. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>In order to implement these changes and synchronize the text of the 5<sup>th</sup> edition Working Draft OFF text with OT 1.8.4 and 1.9 updates, the updates will need to be submitted as input contributions.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Thank you,<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Vladimir<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><a name="_MailEndCompose"><span style='color:#1F497D'><o:p> </o:p></span></a></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> mpeg-otspec [mailto:mpeg-otspec-bounces@lists.aau.at] <b>On Behalf Of </b>Peter Constable<br><b>Sent:</b> Friday, November 12, 2021 1:31 AM<br><b>To:</b> 'MPEG OT Spec list' <mpeg-otspec@lists.aau.at><br><b>Subject:</b> [MPEG-OTSPEC] FYI: OpenType 1.9 beta<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><p style='margin:0in;margin-bottom:.0001pt;background:white;vertical-align:baseline'><span style='font-size:12.5pt;font-family:"Noto Sans";color:black'>A beta for OpenType 1.9 has been published for two-week public review.

The new COLR version also provides greater integration with font variations—something that is not supported at all with OT-SVG. The COLR enhancements were designed jointly with Google, who have been implementing support in the FontTools project, the Skia and Freetype libraries, and in Chrome. It can be tested already in the <a href="https://typedrawers.com/home/leaving?allowTrusted=1&target=https%3A%2F%2Fwww.google.com%2Fchrome%2Fcanary%2F"><span style='color:#1E79A7;border:none windowtext 1.0pt;padding:0in'>Chrome Canary</span></a> builds by browsing to chrome://flags/#colr-v1-fonts to enable the feature.
