v2.1.0

Fixed

• Close tags more correctly, even if the end tag has trailing text.

  For example, </tag bonus> now closes <tag> correctly.
  The trailing content is not available to parsers.

• Fix quadratic CPU usage in SGMLParser.feed().

  This can occur when a large document with an unfinished token
  (like <a href="...) is fed into the parser in very small increments.

  The new implementation doesn't significantly change peak memory usage.

Changed

• Improve the closing tag search behavior of SGMLParser.finish_endtag().

  Previously, the method always searched the entire tag stack
  to close the innermost tag, which had a higher search cost.
  The tag stack is now searched in reverse order
  and breaks on the first matching tag.

v2.0.1

Changed

• Include documentation, tests, and supporting files in the source distribution. (#12)

v2.0.0

Breaking changes

• Switch from a namespace package to a regular package. (kurtmckee/feedparser#585)

  The namespace package caused issues in the feedparser dev environment
  due to conflicts with editable installs of feedparser.
  It also adversely affected deployments for users
  due to separated installs between system and venv environments.

  The new package name is feedparser_sgmllib.

Documentation

• Use the sphinx-issues plugin to link to issues and PRs.

Development

• Use scriv to manage the CHANGELOG.
