 Yours truly worked on this for about 7 months. This was also my first zig
 project which I never went to (nor really needed to) come back and clean up.
 
+Update 2022-02: I am reviving it:
+- updated to stage2, so it works on nightly again.
+- I learned some zig over the last year, will be cleaning it up.

+Currently it has not been fuzz-tested, so it will crash on invalid data. Please
+use `ReleaseSafe` until it is fuzzed.

 Dependencies
 ------------
 
-1. zig v0.10. turbonss is implemented in stage1, so will not work with zig
-   v0.11+.
+1. zig 0.11.0-dev.1580+a5b34a61a or higher.
 2. [cmph][cmph]: bundled with this repository.
