Manticore Search vs Stirling-PDF: at a glance
What is Manticore Search?
Manticore 31.0.7 undoes a 2x COUNT(DISTINCT) slowdown its own collation fix caused.
Manticore Search's 31.x tags so far are fixes rather than features. 31.0.3 and 31.0.4 were CI and packaging work; 31.0.7 restores string COUNT(DISTINCT) speed after the 29.18.5 collation fix made it 2x slower (1.1 s to 2.4 s on the logs10m benchmark) by calling tolower() per byte. A lookup table replaces the call without changing hash values, so secondary indexes and histograms stay compatible.
What is Stirling-PDF?
Stirling PDF is clearing the decks — six weeks of hotfixes ahead of a promised big release.
Every release in this window is corrective. 2.14.3 fixes tool operations failing on Debian 12 and Fedora 44, concurrency problems on merge, an automation bug in image removal, and crashes on 2GB PDFs, plus Linux startup and a Windows ARM64 test build. Before it, 2.14.2 patched Postgres user-data loading, 2.14.1 stopped PostHog loading before opt flags were read and fixed certificate signing, and 2.13.2 covered security fixes and desktop performance. The one feature release is 2.14.0, which added hardware token signing via PKCS#11 smart cards and OS certificate stores on desktop.
Manticore Search vs Stirling-PDF: editorial side-by-side
Manticore Search
5.0DEVOPS
Manticore 31.0.7 undoes a 2x COUNT(DISTINCT) slowdown its own collation fix caused.
◆ Current state
Manticore Search's 31.x tags so far are fixes rather than features. 31.0.3 and 31.0.4 were CI and packaging work; 31.0.7 restores string COUNT(DISTINCT) speed after the 29.18.5 collation fix made it 2x slower (1.1 s to 2.4 s on the logs10m benchmark) by calling tolower() per byte. A lookup table replaces the call without changing hash values, so secondary indexes and histograms stay compatible.
◆ Where it's heading
October has been correctness work on string handling (range filters, collation-aware COUNT(DISTINCT)) followed by fixing the performance cost of those fixes. The 31.x line still appears in the feed without notes on what features justified the major version.
◆ Prediction
Expect more 31.0.x patches in this vein. What new capability defines 31.x remains unclear from these entries.
Stirling-PDF
5.0DEVOPS
Stirling PDF is clearing the decks — six weeks of hotfixes ahead of a promised big release.
◆ Current state
Every release in this window is corrective. 2.14.3 fixes tool operations failing on Debian 12 and Fedora 44, concurrency problems on merge, an automation bug in image removal, and crashes on 2GB PDFs, plus Linux startup and a Windows ARM64 test build. Before it, 2.14.2 patched Postgres user-data loading, 2.14.1 stopped PostHog loading before opt flags were read and fixed certificate signing, and 2.13.2 covered security fixes and desktop performance. The one feature release is 2.14.0, which added hardware token signing via PKCS#11 smart cards and OS certificate stores on desktop.
◆ Where it's heading
The project is consolidating a desktop application on top of what was a server tool, and the defect pattern shows where that hurts: platform-specific startup failures, OS certificate integration, ARM64 builds, large-file memory behaviour. Hardware token signing is the strategically interesting piece, since it moves the product toward legally meaningful signatures that a browser-only tool cannot offer. The 2.14.3 notes state a large feature release is two to three weeks out.
◆ Prediction
The changelog explicitly promises a substantial feature release in two to three weeks, and the stabilisation pattern supports that. Hardware token signing spreading beyond desktop-only is the natural extension of the 2.14.0 work.
