Documentation

• note strict changes shipped in 0.18.11 (#4300) (cbb1fce)

BREAKING CHANGES

• Missing character metrics now reported via strict with error code symbolNotInFont, changing warning formatting, calling any strict callbacks, and producing errors in strict: "error" mode. Also, strict callbacks returning undefined or null now warn instead of ignoring the issue (and no longer typecheck); return false or "ignore" to suppress warnings.
