What is KACE?

KACE's real news lands in two numbered releases a quarter; the rest of the feed is fix notices

KACE runs two product lines through one changelog: the on-prem Systems Management Appliance, which ships numbered releases every few months, and KACE Cloud, which deploys continuously and reports each deploy as a fix notice. SMA 15.1 in July was the substantive release of the period, adding a native Windows ARM64 agent, Windows 11 24H2 feature-update support, HTTPS-only appliance access, and Microsoft 365 OAuth for outbound mail — all of it tracking Microsoft platform changes rather than opening new ground. Everything since has been Cloud maintenance, most of it in Apple and Android device-enrollment paths, plus the monthly Patch Tuesday catalog notice.

What is Calibre-Web?

A self-hosted ebook library growing one reader feature and one format at a time.

Calibre-Web is a browser front-end for Calibre libraries, releasing roughly annually under versioned codenames. The recent line has concentrated on three areas: the built-in EPUB and comic readers (themes, font size, page counts, Kepub support, saved reading positions), bulk operations on the book table (multi-edit, delete, archive, mark as read), and metadata handling on upload — including extraction from a dozen audio formats. Kobo sync and OPDS keep receiving targeted fixes.

KACE's real news lands in two numbered releases a quarter; the rest of the feed is fix notices

◆ Current state

KACE runs two product lines through one changelog: the on-prem Systems Management Appliance, which ships numbered releases every few months, and KACE Cloud, which deploys continuously and reports each deploy as a fix notice. SMA 15.1 in July was the substantive release of the period, adding a native Windows ARM64 agent, Windows 11 24H2 feature-update support, HTTPS-only appliance access, and Microsoft 365 OAuth for outbound mail — all of it tracking Microsoft platform changes rather than opening new ground. Everything since has been Cloud maintenance, most of it in Apple and Android device-enrollment paths, plus the monthly Patch Tuesday catalog notice.

◆ Where it's heading

The on-prem line is being modernized to track Microsoft's platform changes rather than extended into new territory — ARM64 coverage, UUP-based feature updates, OAuth mail, and mandatory TLS are all catch-up moves against dependencies KACE does not control. Cloud is where the volume is, and its fix stream reads as a product still stabilizing its MDM enrollment surface: Apple DEP profiles, restriction sets, WiFi payloads, and Android AMAPI have each needed correction in the last month. The split is clear enough that the two lines could be read as different maturity stages of the same portfolio.

◆ Prediction

Expect the next SMA numbered release to continue the Microsoft-alignment work rather than open a new capability area, with Cloud fix notices continuing at roughly weekly cadence in between. The entries give no indication of when that release lands.

C0.0

A self-hosted ebook library growing one reader feature and one format at a time.

◆ Current state

Calibre-Web is a browser front-end for Calibre libraries, releasing roughly annually under versioned codenames. The recent line has concentrated on three areas: the built-in EPUB and comic readers (themes, font size, page counts, Kepub support, saved reading positions), bulk operations on the book table (multi-edit, delete, archive, mark as read), and metadata handling on upload — including extraction from a dozen audio formats. Kobo sync and OPDS keep receiving targeted fixes.

◆ Where it's heading

The project is steadily reducing how often users need to open Calibre itself. Each release moves another desktop-app operation into the browser — bulk edits, metadata backup and merge, multi-format upload with drag and drop — while the reader gains the comfort features that make it a destination rather than a preview. The other constant is compatibility maintenance: Calibre 9 support, Python 3.12, FreeBSD binary paths, and repeated release notes warning that new dependencies must be installed first.

◆ Prediction

Expect the next release to continue widening bulk operations and reader polish, with compatibility work tracking whatever upstream Calibre and Python ship. The recurring dependency warnings suggest packaging friction remains unresolved.
