Sulu
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
A side-by-side editorial comparison of Eleventy and SalesBlink — release velocity, themes, recent moves, and the top alternatives to consider.
The v4 canary line is being renamed Build Awesome while 3.x is kept on pure maintenance.
Two lines run in parallel. The 3.x branch gets dependency-only releases — 3.1.5 and 3.1.6 explicitly ship no core code changes, after 3.1.3 and 3.1.4 failed to publish and were left as immutable dead tags. The v4 alpha train, meanwhile, is where the work is: Node minimum raised to 22.15, page.inputPathDir and page.dir removed, batched incremental builds added, and a large refactor of the Nunjucks fork onto a fully-async prerelease. The releases themselves now carry the Build Awesome name and offer an @awesome.me/buildawesome install alongside @11ty/eleventy@canary.
Cold-email tooling that wants you to skip its own dashboard.
SalesBlink runs cold email sequences — sending, deliverability, replies, and booking. The past few months added an agent layer on top of that: an MCP server in April, an OpenClaw integration in May for autonomous outreach, and in July an AI Copilot inside the dashboard that creates and manages sequences from a prompt. The conventional product kept moving in parallel — a rebuilt meeting scheduler with whitelabel support, email security gateway detection that skips leads whose employers block cold mail, and a July roundup whose headline item is reply detection dropping from hours to seconds.

v4 is accumulating breaking changes faster than it is stabilizing — three of the entries in this window announce removals or minimum-version bumps, and alpha.10 exists only to hotfix a regression alpha.9 introduced. The Nunjucks refactor is the biggest bet: making the fork fully async removes the need for async-specific template tags, but the release notes flag it as risky for existing Nunjucks users. The naming change is proceeding on the same timeline, so users tracking canary are absorbing an identity shift and an API shift at once.
Expect more v4 alphas carrying breaking removals before any beta, with the Nunjucks async refactor generating follow-up regressions; 3.x looks likely to keep receiving dependency-only patches with no core changes.

Two threads, and they point the same way. The deliverability work treats sending capacity as the scarce resource — detecting gateways that would swallow the message, testing inbox placement, selling pre-configured mailboxes with DNS and DMARC handled — so that no send is wasted. The agent work attacks the other cost, the operator's time in the interface. Announcing an MCP server with "ditch the dashboard" and then shipping a Copilot inside the dashboard is the same bet placed twice: sequences described rather than assembled.
The AI credits framing that arrived with the Copilot is the thing to watch — a usage-metered agent sitting on top of a seat-priced outreach tool is a pricing question the entries raise but do not settle.
