BREAKING CHANGES AND DEPRECATIONS
+ * tika-pipes-* and two tika-langdetect modules no longer pull in a log4j
backend;
+ embedding apps (and their PipesServer forks) must add an slf4j binding,
e.g.
+ log4j-slf4j2-impl (TIKA-5058).
+
* Markdown output writes math as $`...`$ (a code span, which GitHub and
GitLab
render as math) instead of raw $...$, so text in a math span can no
longer become
HTML or links. Readers that only know $...$, such as pandoc, show it as
code. Only
