HelpSpot 5.7.3

Important: This release includes several security fixes. All HelpSpot customers are encouraged to update as soon as possible. HelpSpot Cloud customers will be upgraded automatically.

Bug Fixes

• Survey buttons not displaying in Outlook — Customer satisfaction survey buttons embedded in outgoing emails were not rendering for recipients on the Microsoft 365 / new Outlook desktop client. The buttons are now rendered via VML so they display correctly in Outlook.
• Updater ignored a “no” response — Answering no at the updater’s version-confirmation prompt no longer proceeds with the update. The command now stops as expected.
• SQL Server version check on modern servers — Fixed the system check that could incorrectly fail against newer Microsoft SQL Server versions.
• Database session driver — The HS_Sessions table is recreated on upgrade, so installations configured with SESSION_DRIVER=database no longer fail with a missing-table error.
• Mail fetching worker stability — Inbound mail processing now handles unexpected errors during fetch without crashing the background worker, so a single problematic message can’t stall the mail queue.
• Scheduled maintenance commands could error — The scheduled errors:purge and filters:clean-perf tasks could fail with an exception during schedule:run. These console commands now complete and report success correctly.
• AI category processing — Fixed an issue where the AI category data sent during new-request processing could exceed the service size limit, causing categorization to fail.

Changes

• intl extension now enforced in system checks — The pre-flight system check now correctly lists the PHP intl extension as required, so a missing extension is reported up front during install or upgrade instead of causing errors later. Make sure intl is enabled before upgrading.
• LDAP extension system check — The pre-flight check now verifies the PHP ldap extension is present, and a missing extension no longer crashes startup. Upgrades surface a clear message rather than a fatal “function not found” error.
• Automation rule help text — Added inline helper text to the Request History full-text search for condition to clarify its matching behavior, particularly on SQL Server.

Security

• Various security improvements.
