What is KACE?

KACE extends its PHP2SHELL fix to the SDA deployment appliance, six days after disclosure.

KACE has now patched the critical PHP2SHELL vulnerabilities across both appliances: SMA 15.1 and 15.0 on October 23, and the SDA 9.3 deployment appliance on October 27. SMA also gained official support for Windows 11 26H2 agents and patches, following KACE Cloud's 26H2 support a few days earlier.

What is SiYuan?

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

KACE vs SiYuan: editorial side-by-side

K
KACE
COLLAB
5.0

KACE extends its PHP2SHELL fix to the SDA deployment appliance, six days after disclosure.

◆ Current state

KACE has now patched the critical PHP2SHELL vulnerabilities across both appliances: SMA 15.1 and 15.0 on October 23, and the SDA 9.3 deployment appliance on October 27. SMA also gained official support for Windows 11 26H2 agents and patches, following KACE Cloud's 26H2 support a few days earlier.

◆ Where it's heading

The changelog is dominated by security response and OS-version coverage, with both SMA branches patched in lockstep. Feature work is limited to agent reliability fixes. KACE behaves like a maintained endpoint-management line rather than one being redirected.

◆ Prediction

Expect November Patch Tuesday content and further cumulative patches on both SMA branches. The entries don't point to new feature work.

5.0

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

◆ Current state

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

◆ Where it's heading

The 3.8.x line keeps turning databases and mind maps into structured tools that act on the block graph, and the built-in agent is gaining reach into document content such as PDFs. The release cadence is fast and noisy, with most builds repeating the same cumulative notes.

◆ Prediction

A stable 3.8.9 is likely within days, with little added beyond fixes now that it has reached RC.
