**** Release 1.12.2 [PENDING]

• ...

**** Release 1.12.1 [2019-May12]

• Change: removed deprecated method to disable TLS cert checking Connection.validateTLSCertificates().

• Change: some internal methods have been rearranged; if you extended any of the Jsoup internals you may need to make
  updates.

• Improvement: documents now remember their parser, so when later manipulating them, the correct HTML or XML tree
  builder is reused, as are the parser settings like case preservation.
  https://github-redirect.dependabot.com/jhy/jsoup/issues/769

• Improvement: Jsoup now detects the character set of the input if specified in an XML Declaration, when using the
  HTML parser. Previously that only happened when the XML parser was specified.
  https://github-redirect.dependabot.com/jhy/jsoup/issues/1009

• Improvement: if the document's input character set does not support encoding, flip it to one that does.
  https://github-redirect.dependabot.com/jhy/jsoup/issues/1007

• Improvement: if a start tag is missing a > and a new tag is seen with a <, treat that as a new tag. (This differs
  from the HTML5 spec, which would make at attribute with a name beginning with <, but in practice this impacts too
  many pages.
  https://github-redirect.dependabot.com/jhy/jsoup/issues/797

• Improvement: performance tweaks when parsing start tags, data, tables.

• Improvement: added Element.nextElementSiblings() and Element.previousElementSiblings()
  https://github-redirect.dependabot.com/jhy/jsoup/pull/1054

• Improvement: treat center tags as block tags.
  https://github-redirect.dependabot.com/jhy/jsoup/pull/1113

• Improvement: allow forms to be submitted with Content-Type=multipart/form-data without requiring a file upload;
  automatically set the mime boundary.
  https://github-redirect.dependabot.com/jhy/jsoup/pull/1058

• Improvement: Jsoup will now detect if an input file or URL is binary, and will refuse to attempt to parse it, with
  an IO exception. This prevents runaway processing time and wasted effort creating meaningless parsed DOM trees.
  https://github-redirect.dependabot.com/jhy/jsoup/issues/1192

• Bugfix: when using the tag case preserving parsing settings, certain HTML tree building rules where not followed
  for upper case tags.
  https://github-redirect.dependabot.com/jhy/jsoup/issues/1149

• Bugfix: when converting a Jsoup document to a W3C DOM, if an element is namespaced but not in a defined namespace,
  set it to the global namespace.
