Manticore Search vs Stirling-PDF: at a glance
What is Manticore Search?
Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.
Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.
What is Stirling-PDF?
Stirling PDF plans to drop LibreOffice for its own converter within two weeks
Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.

Manticore Search
5.0DEVOPS
Manticore keeps patching 31.x, now fixing a FREEZE crash and a DocID ordering bug.
◆ Current state
Manticore Search's 31.x tags remain fixes rather than features. 31.0.7 restored string COUNT(DISTINCT) speed after a collation fix had doubled it to 2.4 s, and 31.0.18 bumped the Buddy sidecar for PHP 8.5. 31.0.19 fixes deferred real-time kills that sorted document IDs as signed numbers, and 31.0.21 stops FREEZE from crashing when it includes a distributed table.
◆ Where it's heading
The 31.x line is in steady correctness work, with several tags a week and each fixing one edge case in real-time tables, backups or query paths. No feature work has shown up in the feed since 31.0 began.
◆ Prediction
Expect more single-fix 31.0.x tags; the entries give no sign of when the next feature release lands.
Stirling-PDF
5.0DEVOPS
Stirling PDF plans to drop LibreOffice for its own converter within two weeks
◆ Current state
Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.
◆ Where it's heading
The project is replacing third-party dependencies with its own components. 3.3.0 says Office Convert should become the default next week and LibreOffice should be removed the week after, which would shrink the install and change conversion results for every user.
◆ Prediction
Expect Office Convert to become the default converter in the next release, then LibreOffice removed, as 3.3.0's notes lay out. Conversion bug reports will decide whether that schedule holds.
