Skaffold vs Stirling-PDF: at a glance
What is Skaffold?
Skaffold 2.25 finally carries notes, and they are dependency bumps and a Go 1.27 upgrade.
Skaffold cut 2.19 through 2.25 between April and mid-September on a roughly monthly rhythm, after a short 2.18 patch series in March and April. Most entries are just install commands per platform. Version 2.25.0 on September 16 is the first in this window with a change list, and it is all maintenance: Go 1.27.1, containerd, gRPC, buildkit and go-git bumps, plus a docs announcement on the V2 and YAML reference pages.
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.

Skaffold
0.0DEVOPS
Skaffold 2.25 finally carries notes, and they are dependency bumps and a Go 1.27 upgrade.
◆ Current state
Skaffold cut 2.19 through 2.25 between April and mid-September on a roughly monthly rhythm, after a short 2.18 patch series in March and April. Most entries are just install commands per platform. Version 2.25.0 on September 16 is the first in this window with a change list, and it is all maintenance: Go 1.27.1, containerd, gRPC, buildkit and go-git bumps, plus a docs announcement on the V2 and YAML reference pages.
◆ Where it's heading
The monthly minors look like dependency hygiene rather than feature work, and the empty New Features and Fixes sections in 2.25 confirm it for that release. No entry has appeared since mid-September, which breaks the monthly rhythm the project held through the summer.
◆ Prediction
If cadence resumes, expect a 2.26 with another round of Go and dependency updates; the feed gives no sign of feature work.

5.0DEVOPS
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.
