 V 1.0 release is planned for December 2019.
 
+## Notes
+
 GitHub marks V's code as written in Go. It's actually written in V, GitHub doesn't support the language yet.
 
 The compilation is temporarily slower for this release:
-
 - Debug builds are used (use `v -prod -o v` to get faster compilation).
 - The new formatter runs on every single token and slows the compiler down by ~20%. This will be taken care of.
 - There are a lot of known issues that are quick to fix (like function lookups being O(n)).
 
+There's some old hacky code written when V was 2 months old. All of it will be quickly cleaned up. There are ~500 lines of C code, which will be removed by the end of June.
