 - Improve support for Windows cross compilation on targets with case sensitive file systems.
 - Add "sources" support to library `manifest.json`, defaults to root folder if unspecified.
 - Add char_at method in DString and operators [], len, []= and &[].
+- Add `-q` option, make `--run-once` implicitly `-q`.
+- Add `-v`, `-vv` and `-vvv` options for increasing verbosity, replacing debug-log and debug-stats options.
 
 ### Fixes
 - Fix bug where `a > 0 ? f() : g()` could cause a compiler crash if both returned `void!`.
