This is a bug-fix release that resolves two dozen issues, and also includes an important update to the speech-rule engine that underlies the accessibility tools provided by MathJax via the accessibility menu.

Among the bugs that are fixed are:

• The misplacement of vector arrows that first appeared in Safari 10 (#1709 and #1737).
• An error with certain uses of AMScd in CommonHTML output (#1691)

See the 2.7.2 milestone for details.
