Stirling-PDF vs Zeebe: at a glance
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.
What is Zeebe?
Zeebe opens the 8.11 alpha cycle while 8.10 settles into patch releases.
Zeebe, Camunda's workflow engine, has moved past the 8.10 alpha cycle: 8.10.7-rc1 is a patch candidate and 8.11.0-alpha1 is in release candidates. The first 8.11 candidate fixes a cluster of Java client bugs where streaming job workers stopped polling or let batches expire at maxJobsActive, and adds cluster secrets in managed mode and Oracle Data Guard replication-lag monitoring. Optimize patches on the 8.6 and 8.7 lines continue alongside.

◆ 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.
Zeebe
5.0DEVOPS
Zeebe opens the 8.11 alpha cycle while 8.10 settles into patch releases.
◆ Current state
Zeebe, Camunda's workflow engine, has moved past the 8.10 alpha cycle: 8.10.7-rc1 is a patch candidate and 8.11.0-alpha1 is in release candidates. The first 8.11 candidate fixes a cluster of Java client bugs where streaming job workers stopped polling or let batches expire at maxJobsActive, and adds cluster secrets in managed mode and Oracle Data Guard replication-lag monitoring. Optimize patches on the 8.6 and 8.7 lines continue alongside.
◆ Where it's heading
Job-worker reliability is the recurring thread: 8.10's alpha5 added lease control and fixed secret-resolution latency, and 8.11 alpha1 fixes how workers handle capacity limits. Camunda maintains several older lines at once, so much of the feed is tag churn.
◆ Prediction
8.11.0-alpha1 should ship final after its release candidates, with 8.10.7 as the next 8.10 patch. The entries do not show what 8.11's headline feature will be.
