+- **(breaking)** [#112](https://github.com/jamwaffles/ssd1306/pull/112) Upgrade to embedded-graphics 0.6.0
 - [#107](https://github.com/jamwaffles/ssd1306/pull/107) Migrate from Travis to CircleCI
 - [#105](https://github.com/jamwaffles/ssd1306/pull/105) Reduce flash usage by around 400 bytes by replacing some internal `unwrap()`s with `as` coercions.
 - [#106](https://github.com/jamwaffles/ssd1306/pull/106) Optimise internals by using iterators to elide bounds checks. Should also speed up `GraphicsMode` (and `embedded-graphics` operations) with a cleaned-up `set_pixel`.
