 * Next Version
-** Remove CSS pixel ratio > 1 support in Safari
-   Mac OS X Safari has scaling bugs, and iOS Safari has lower
-   performance.
 ** Use standard Unicode codepoints for icon fonts
    This is done via the [[https://korewanetadesu.com/pages/fontstandard.html][Font Standard]] icon font.
-** Work around incorrect Safari JIT generation
-   Some details of the symptoms / likely-but-unproven cause at
-   https://korewanetadesu.com/safari-jit-bug.html.
 ** Sped up background and book noise animations
 ** Cat paws
 ** DONE Migrate to nw.js (from node-webkit)
 
+** DONE Safari 8 / iOS 8 support
+   This is the first version to support Safari on Mac OS X and iOS.
+
+   The primary problem in earlier versions [[https://korewanetadesu.com/safari-jit-bug.html][appears to be a bug in
+   Safari's JIT when optimizing functions that modify JavaScript's
+   ~arguments~ object]]. Code triggering this bug was rewritten to avoid
+   modifying ~arguments~. This bug is further described in and seems
+   to still exist in current versions of WebKit's new "FTL" JIT.
+
+   Prior to OS X 10.10, Safari on OS X will show [[https://bugs.webkit.org/show_bug.cgi?id=134854][artifacts on HiDPI
+   ("Retina") screens due to a bug in its compositing]].
+
+   Offline play is not supported in iOS 8 or earlier [[https://bugs.webkit.org/show_bug.cgi?id=138506][due to WebKit bug
+   138506]]; this is scheduled to be fixed in iOS 9.
+** Improved touchscreen usability

 * Open Issues
-** TODO Safari handles WebGL device pixel scaling incorrectly
-   Given a device pixel ratio of 2, Safari will scale the backbuffer
-   incorrectly when rendering it (seems like it scales it down using
-   bilinear interpolation, then back up with the same) resulting in
-   something that looks worse than leaving the DPR set to 1.
-
-   Currently DPR is fixed to 1 for Safari.
-
-   https://bugs.webkit.org/show_bug.cgi?id=134854
-** TODO Still some "random stalls" in Safari.
-   Likely due to the same JIT bug manifesting in some other ways.
-** TODO Choppy / staticy audio on iOS
-   Especially when backgrounding, e.g. switching tabs. There's
-   probably no easy way to avoid this.
+** TODO No longer working at all on iOS
 ** TODO Scrolling is broken in licensing window
 This began when upgrading to nw.js 0.12 (from node-webkit 0.10.4). If
 it's broken one place it's probably broken other places also.
+
+Not reproducible in Chrome 42, so it's possible this was some
+transient Chromium bug that will be gone in newer NW.js.
+** TODO Disable per-pixel noise shader if slow
+** TODO Disable full-frame scroll bounce
