+## Version 1.2.0
+
+- Breaking change: We new include the condensed versions of our fonts in the builds ("Normal"), and the normal width ("Extended"). Not confusing at all, right?
+
+- Updated build plans – Removed specified variants for now to generate all variants
+
+
+## Version 1.1.0
+
+- Updated build plans – Mono and Sans now build with the same characters, weights and widths
+- New characters:
+  - Alphas: `N`, `W`, `X`, `g`, `x`, `y`
+  - Numerics: `0`, `4`, `5`, `7`, `8`, `9`
+  - Symbols: `*`, `_`, `(`, `{`, `&`, `%`, `|`, `?`
+
+Characters were chosen to be scanable (`6` & `9` are more differentiated for example.) Some changes are subjective (`(` for example), and may be updated or walked back in the future.

+## Version 1.0.0
