Apache Arrow Rust vs Stirling-PDF: at a glance
What is Apache Arrow Rust?
Arrow Rust cuts release candidates on three older lines at once.
Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.
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.

Apache Arrow Rust
5.0DEVOPS
Arrow Rust cuts release candidates on three older lines at once.
◆ Current state
Arrow Rust shipped 60.1.0 on October 28, with Parquet encryption keys redacted from Debug output and read-ahead planning in the push decoder, after 59.3.2 and 58.4.1 fixed a use-after-free in Buffer::shrink_to_fit. On November 13 the 57, 58 and 59 maintenance lines tagged release candidates for 57.3.3, 58.4.2 and 59.3.3 within a minute of each other. The tags carry only version bumps; the changelogs are not in the feed.
◆ Where it's heading
The project keeps four major lines alive and patches them together, so downstream users on older Arrow versions still get fixes. Feature work stays on the 60 line.
◆ Prediction
Expect the three patch releases to publish after the vote period, and a 60.2.0 or 61.0.0 candidate to follow.
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.
