What is Umbraco CMS?

Umbraco cuts release candidates on three branches at once and is paying down backoffice startup cost.

All three visible entries are release candidates, published across three live branches — 18.1, 17.6 and the long-term 13.16 — with 18.1 and 17.6 cut on the same day and sharing most of their pull requests. The 17.6 candidate is the substantive one: a block of backoffice performance work (coalesced JavaScript chunks, manifests embedded to cut startup requests, parallelized boot API calls, a new content index) alongside new UFM and picker components and configurable scheduled publishing. Several dependency entries are security-driven — MessagePack updated for advisories, SQLitePCLRaw pinned off a vulnerable build.

What is Salesloft?

Post-merger Salesloft is racing to make its data reachable from whatever AI tool the rep already has open.

Salesloft publishes monthly release notes covering the whole post-merger surface — its own cadence and conversations products plus Clari and Groove. The through-line since April is agentic access: an MCP server exposing live pipeline, call and account data to AI tools, then that same server packaged as a ChatGPT custom connector. Both sit behind the Salesloft Agentic add-on and an admin toggle. Elsewhere the notes are governance and analytics work — call recording visibility tiers, AI usage metrics, sorting and filtering.

Umbraco CMS vs Salesloft: editorial side-by-side

5.0

Umbraco cuts release candidates on three branches at once and is paying down backoffice startup cost.

◆ Current state

All three visible entries are release candidates, published across three live branches — 18.1, 17.6 and the long-term 13.16 — with 18.1 and 17.6 cut on the same day and sharing most of their pull requests. The 17.6 candidate is the substantive one: a block of backoffice performance work (coalesced JavaScript chunks, manifests embedded to cut startup requests, parallelized boot API calls, a new content index) alongside new UFM and picker components and configurable scheduled publishing. Several dependency entries are security-driven — MessagePack updated for advisories, SQLitePCLRaw pinned off a vulnerable build.

◆ Where it's heading

Two threads run through the new-generation branches. One is making the rewritten backoffice cheap to boot, attacking request count rather than payload size — the classic sign that a single-page admin rewrite has hit its startup-latency wall. The other is filling in the component and property-editor surface (element pickers with value summaries and type validation, media thumbnails, member and element name components) so the new extension model has parts to build with. The 13.x LTS gets dependency maintenance only, which is the expected end-of-life shape.

◆ Prediction

Expect these candidates to promote to stable with the performance set intact, and the next cycle to keep extending property editors and the Management API surface rather than opening a new capability area.

3.8

Post-merger Salesloft is racing to make its data reachable from whatever AI tool the rep already has open.

◆ Current state

Salesloft publishes monthly release notes covering the whole post-merger surface — its own cadence and conversations products plus Clari and Groove. The through-line since April is agentic access: an MCP server exposing live pipeline, call and account data to AI tools, then that same server packaged as a ChatGPT custom connector. Both sit behind the Salesloft Agentic add-on and an admin toggle. Elsewhere the notes are governance and analytics work — call recording visibility tiers, AI usage metrics, sorting and filtering.

◆ Where it's heading

The AI story is deliberately being told twice: new metrics count Account researched, Person researched and Agent tasks completed so customers can see AI adoption, while MCP makes that AI reachable from outside Salesloft entirely. That second move is the more consequential one — it concedes the rep may live in ChatGPT and positions Salesloft as the data layer rather than the interface. The Clari merger is still mostly cross-referenced rather than integrated in these notes.

◆ Prediction

Expect the Agentic add-on to keep accumulating the AI functionality while base tiers get the analytics that measure it, and further connectors beyond ChatGPT for the same MCP server. How deeply Clari and Salesloft actually merge in the product remains unstated.
