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 Zettlr?
A markdown editor grinding through polish, with custom shortcuts finally landing after years
Zettlr is a desktop markdown editor for academic and long-form writing, releasing roughly monthly. The recent line is dominated by file-manager work — workspace sorting, folder colors, closing all standalone files, more reliable folder opening — alongside citation quality improvements and a visual indicator for long-running tasks such as PDF export. Version 4.7.0 finally added user-definable custom shortcuts, described as a years-old request. Two releases in the window are explicitly framed as fixing rather than adding, including regressions from an editor codebase transition.
KACE vs Zettlr: editorial side-by-side
KACE
5.0COLLAB
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.

2.5COLLAB
A markdown editor grinding through polish, with custom shortcuts finally landing after years
◆ Current state
Zettlr is a desktop markdown editor for academic and long-form writing, releasing roughly monthly. The recent line is dominated by file-manager work — workspace sorting, folder colors, closing all standalone files, more reliable folder opening — alongside citation quality improvements and a visual indicator for long-running tasks such as PDF export. Version 4.7.0 finally added user-definable custom shortcuts, described as a years-old request. Two releases in the window are explicitly framed as fixing rather than adding, including regressions from an editor codebase transition.
◆ Where it's heading
This is a mature application paying down the cost of a rewrite while filling in the ergonomics its users have accumulated requests for. The file manager has been the focus across four consecutive releases, which suggests navigation was the friction point users complained about most. Security fixes appear repeatedly and are notable in kind rather than volume: escaping path names passed to shell commands during export closed a path to unintended command execution. Nothing here changes what the product is — it makes the existing product less irritating.
◆ Prediction
Expect the file manager and editor-transition regressions to keep absorbing releases, with custom shortcuts likely to grow configuration surface now that the mechanism exists.
