Release Notes

KaTeX/KaTeX (katex)

v0.19.1

Compare Source

Bug Fixes

• allow percent sign in raw argument type (#​4307) (6971e5c)

v0.19.0

Compare Source

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.
