Tika 1.x removed: all sites now use Tika 3

As previously announced, Tika 1.18 and 1.21 have been removed from the Pantheon platform. All sites now run Tika 3 regardless of the tika_version setting in pantheon.yml.

Action Required

• If you have not already done so, remove tika_version: 1 from your pantheon.yml before May 12, 2026.
  • Any tika_version: 1 entries will be ignored until May 12, 2026, at which point they will be rejected and prevent deployments.
• Update the used Tika 1.x path to Tika 3, for details see related documentation.
  • Existing Tika 1.x file paths will continue to symlink to the new Tika 3 location for the time being, but these symlinks will be removed at a later date.
