What is Liquidsoap?

Liquidsoap 2.5.0 reaches its first release candidate while 2.4 keeps getting patches.

Liquidsoap's 2.5.0 work, accumulated in a rolling release since August, reached a first release candidate on October 9, declared feature-complete and meant for staging rather than production. It brings subtitles as a content type, an Icecast-compatible server and a rewritten source composition model where switching fades by default. The 2.4 line continues in parallel: 2.4.6 on October 18 fixed fades, Icecast reconnection with chunked output and crossfade metadata.

What is Stirling-PDF?

Stirling PDF's 3.x line ships bulk processing, org-wide signing and fortnightly feature releases

Stirling PDF 3.0 in late September added the PDF Processor for running tools across folders, FTP or S3 sources, optional AI classification and extraction, free OAuth SSO and a free allowance of 1,000 automated PDFs a month. Releases since have arrived about every two weeks: 3.1.0 made group signing (Stirling Sign) default for new users and trialled an embedded Office converter, 3.2.0 replaced the multi-tool with a Page Editor and let password-protected PDFs be used without removing the password, and 3.2.1 and 3.2.2 added viewer and annotation features.

Liquidsoap vs Stirling-PDF: editorial side-by-side

L5.0

Liquidsoap 2.5.0 reaches its first release candidate while 2.4 keeps getting patches.

◆ Current state

Liquidsoap's 2.5.0 work, accumulated in a rolling release since August, reached a first release candidate on October 9, declared feature-complete and meant for staging rather than production. It brings subtitles as a content type, an Icecast-compatible server and a rewritten source composition model where switching fades by default. The 2.4 line continues in parallel: 2.4.6 on October 18 fixed fades, Icecast reconnection with chunked output and crossfade metadata.

◆ Where it's heading

The project is in the run-up to a breaking release: 2.5 changes how switch, fallback, rotate and random take their arguments, so scripts will need edits. Keeping 2.4 patched in parallel gives users time to test before moving.

◆ Prediction

Further 2.5.0 release candidates and then a 2.5.0 final are the next likely entries, with another 2.4.x patch possible alongside.

S5.0

Stirling PDF's 3.x line ships bulk processing, org-wide signing and fortnightly feature releases

◆ Current state

Stirling PDF 3.0 in late September added the PDF Processor for running tools across folders, FTP or S3 sources, optional AI classification and extraction, free OAuth SSO and a free allowance of 1,000 automated PDFs a month. Releases since have arrived about every two weeks: 3.1.0 made group signing (Stirling Sign) default for new users and trialled an embedded Office converter, 3.2.0 replaced the multi-tool with a Page Editor and let password-protected PDFs be used without removing the password, and 3.2.1 and 3.2.2 added viewer and annotation features.

◆ Where it's heading

The product is moving from a self-hosted toolbox to an automation and workflow platform with metered hosted services attached. Feature releases come quickly, with visible regressions fixed in the next point release.

◆ Prediction

Expect Stirling Office Convert to move toward default and native desktop, as the 3.1.0 notes say is planned, plus continued Processor work.
