+
+### New Features
+- Added `fontHinting` attribute (off by default, matching the weights of fonts to browser rendering). Setting it to `true` may result in crisper edges but adds some weight to the font.
+
+### Bugfixes
+- Text spacing
+  - Setting `letterSpacing` no longer indents text at beginning of line
+  - `letterSpacing` now properly handles negative values
+- Improved accuracy of measureText()
+  - Now uses font metrics' default leading when a lineHeight is left unspecified in the `ctx.font` string (NB: this is likely to cause vertical shifts for non-`alphabetic` baselines)
+  - Updated baseline offset calculations for `middle` & `hanging` to better match browsers
+  - the `actualBoundingBox*` & `lines[].x/y/width/height` rectangles are now just the glyph-occupied area, not whole lineHeight & width of the textblock
+  - Fixed the sign on `actualBoundingBoxLeft` (+ values now mean left of origin)
+  - lines[].baseline now corresponds to the selected ctx.textBaseline, previously it was always the alphabetic baseline
