CHANGE HISTORY
--------------
+- v0.8e (2017/07/30)
+
+ * Add `\surd` to access the sqrt symbol.
+ * Fix bug exposed by expl3 update to booleans.
+ * Add Deja Vu Math TeX Gyre in list of symbols.
+ * Add `\sime` alias for `\simeq` and `\nsimeq` for `\nsime`.
+ (For negations it's helpful when they have consistent naming.)
+
- v0.8d (2017/01/25)
* `vargreek-shape=TeX` and `vargreek-shape=unicode` package options dropped; for consistency and compatibility, `\phi` and `\epsilon` should and will now behave the same as in `TeX`.
