Deprecations:

• highlight(languageName, code, ignoreIllegals, continuation) deprecated as of 10.7
  • Please use the newer API which takes code and then accepts options as an object
  • IE: highlight(code, {language, ignoreIllegals})
  • continuation is for internal use only and no longer supported
• highlightBlock(el) deprecated as of 10.7.
  • Please use highlightElement(el) instead.
  • Plugin callbacks renamed before/after:highlightBlock => before/after:highlightElement
  • Plugin callback now takes el vs block attribute
  • The old API and callbacks will be supported until v12.
