+##### Permissive Hold
+
+As of [PR#1359](https://github.com/qmk/qmk_firmware/pull/1359/), there is a new `config.h` option:
+
+```
+#define PERMISSIVE_HOLD
+```
+
+This makes it easier for fast typists to use dual-function keys. As described in the PR:
+
+Without this, if you let go of a held key inside the tapping term, it won't register.
+
+Example: (Tapping Term = 200)
+
+- SHFT_T(KC_A) Down
+- KC_X Down
+- KC_X Up
+- SHFT_T(KC_A) Up
+
+With permissive hold, if above is typed within tapping term, this will emit `X` (so, Shift+X).
+
+With defaults, if above is typed within tapping term, this will emit `ax`, which I doubt is what anyone really wants
