• avoid deadlock when running indexer with statsd
• introduce INDEXER_JAVA_OPTS environment variable to Docker image which allows to pass extra arguments to the Java process running the indexer

• add support for XML to Universal ctags in the Docker image

• bump Tomcat in Docker image from 10.1.26-jdk17 to 10.1.28-jdk17
• log LDAP connect exceptions (for LDAP authorization plugins)

• WARNING: breaking change for those using authorization and LDAP
  • the format of LDAP configuration used by the authorization plugins now uses YAML (#4599)

• handle situation with history based reindex and nullified changes (avoids indexer exiting with failure)

• fix previous releases

• fix previous release

• fixup of 1.13.13 (missing deliverables)

• handle empty Git repositories gracefully

• history cache is now generated in chunks, lowering memory requirements significantly for repositories with big history
  • as a result, the history cache for repository top level directory is no longer supported
    • the OpenGrokDirHist.gz files in the historycache directories can be removed
• all indexer/web app Git code converted to JGit

• Docker main script rewritten to Python and changed to use per project workflow
  • see https://github.com/oracle/opengrok/wiki/Per-project-management-and-workflow
• OpenGrok now requires Tomcat 10
  • or container that supports Servlet API 5
• Python tools now support custom HTTP headers everywhere
  • this is handy when running indexer in separate machine/VM so that API token
    can be used
• history cache item creation times now reported with FINER log level

• XSS JS module updated
• better debug messages in LdapFilterPlugin

• added options to set parallelism level of history cache creation:
  • --historyThreads
  • --historyRenamedThreads (only makes sense with --renamedHistory=on)
• R language support
• parallelized repository scan (when running the indexer with -S)

• reworked monitoring (e.g. added tags, introduced webapp start meter, ...)
• all cookies now use the SameSite attribute with Secure
• LDAP timeouts are now handled properly in LDAP authorization plugins.
  • readTimeout was introduced for both server pool and individual server configuration
  • for complete list of timeouts see https://github.com/oracle/opengrok/wiki/Authorization-plugins

• enhanced monitoring (suggester, LDAP facade)
  • for monitoring in general see https://github.com/oracle/opengrok/wiki/Monitoring
• URL_ROOT environment variable for Docker image
• enhanced logging for LDAP authorization plugins
• there are now these command timeout types (as specified in configuration, see the wiki for more information):
  • indexerCommandTimeout
  • interactiveCommandTimeout
  • webappStartCommandTimeout
  • restfulCommandTimeout

• new framework for gethering web application statistics based on Micrometer
  • currently Prometheus is supported
• better logging for LDAP authorization plugins
• Lucene 8.6.2
• bug fixes

• fixes to LDAP plugins logging
• new tablesorter
• suggester should work on JDK 14

• #3078: selected projects are preserved across search
• #3010 : add --nestingMaximum switch to allow more than 1 level of repository nesting
• #3028 : on Clear, reset the radio button that selects file type to Any
• JFlex 1.8.2
• Lucene 8.6.1
• mirror.py can now sync Perforce repositories
• support for octopus Git merge commits
• #3145: fix display of plain files when the --economical index option is on
• #1351: history cache generation now respects ignored files/dirs

Note: requires full reindex

• add --nestingMaximum switch
• Lucene 8.5.2
• more efficient handling of Git tags (avoids spawning lots of git processes, instead just one git log per repository is executed to gather the tags)
• Redirect when 1 hit for query of just PATH
