Zulip Server 4.4

on GitHub

4.4 -- 2021-07-22

• Added a tool to fix potential database corruption caused by host OS
  upgrades.
• Fixed a possible denial-of-service attack in Markdown fenced code
  block parsing.
• Smokescreen, if installed, now defaults to only listening on
  127.0.0.1; this prevents it from being used as an open HTTP proxy if
  it did not have other firewalls protecting incoming port 4750.
• Fixed a performance/scalability issue for installations using the S3
  file uploads backend.
• Fixed a bug where users could turn other users’ messages they could
  read into widgets (e.g. polls).
• Fixed a bug where emoji and avatar image requests were sent through
  Camo; doing so does not add any security benefit, and broke custom
  emoji that had been imported from Slack in Zulip 1.8.1 or earlier.
• Changed to log just a warning, instead of an exception, in the case
  that the embed_links worker cannot fetch previews for all links in
  a message within the 30-second timeout. Each preview request within
  a message already has a 15-second timeout.
• Ensured psycopg2 is installed before starting
  process_fts_updates; otherwise, it might fail to start several
  times before the package was installed.
• Worked around a bug in supervisor where, when using SysV init,
  /etc/init.d/supervisor restart would only have stopped, not
  restarted, the process.
• Modified upgrade scripts to better handle failure, and suggest next
  steps and point to logs.
• Zulip now hides the “show password” eye icon that IE and Edge
  browsers place in password inputs; this duplicated the
  already-present JavaScript-based functionality.
• Fixed “OR” glitch on login page if SAML authentication is enabled
  but not configured.
• The send_test_email management command now shows the full SMTP
  conversation on failure.
• Provided a change_password management command which takes a
  --realm option.
• Fixed upgrade-zulip-from-git crashing in CSS source map generation
  on 1-CPU systems.
• Added an auto_signup field in SAML configuration to auto-create
  accounts upon first login attempt by users which are authenticated
  by SAML.
• Provided better error messages when puppet_classes in zulip.conf
  are mistakenly space-separated instead of comma-separated.
• Updated translations for many languages.
