What is q2?

After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.

q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.

What is Spacelift?

Spacelift's AI stopped explaining infrastructure and started deploying it.

The dated window ends in March with Spacelift Intelligence, first-class Terragrunt support, OIDC subject claim customisation and a self-service Templates release. Everything since sits in undated rows and is the more consequential half: a remote MCP server in May, SCIM 2.0 provisioning in June, and in July the ability to ask Intelligence to deploy a module by name, resolved against the Module Registry. An August notice warns that the API will start returning HTTP 500 on internal errors instead of 200.

After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.

◆ Current state

q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.

◆ Where it's heading

The light-dark epic is the shape of how this team retires a Quarto 1 feature: a design doc, then ThemeConfig growing a parsed dark variant, dual theme compilation with color-scheme emission, attributed stylesheet links, a color-mode toggle runtime, an accessibility-aware highlight-style reader, a brand light/dark seam, and an end-to-end verification pass against quarto-web before the docs land. One phase (D) was deferred with its options recorded rather than dropped. Around it, panel-tabset support lands, format.html.css is finally copied and rebased per page, and the llms companion output gains a link-format attribute so authors control where companion links point — the one thread tying this release back to the v0.22.0 work.

◆ Prediction

Expect the remaining Q1 parity items to keep setting the release agenda, with the deferred light-dark phase D and the freshly opened panel-tabset plan the two named strands most likely to fill the next few tags. npx distribution for the standalone Quarto Hub MCP bundle is still the only distribution item the notes explicitly call planned.

Spacelift's AI stopped explaining infrastructure and started deploying it.

◆ Current state

The dated window ends in March with Spacelift Intelligence, first-class Terragrunt support, OIDC subject claim customisation and a self-service Templates release. Everything since sits in undated rows and is the more consequential half: a remote MCP server in May, SCIM 2.0 provisioning in June, and in July the ability to ask Intelligence to deploy a module by name, resolved against the Module Registry. An August notice warns that the API will start returning HTTP 500 on internal errors instead of 200.

◆ Where it's heading

The arc is easy to trace: Intent opened to everyone in December, Intelligence launched in March, an MCP server exposed the platform to outside assistants in May, and by July the AI is performing deployments rather than describing them. Running underneath is the governance work that makes that defensible — module sharing permissions, OIDC claims, SCIM — because an agent that can deploy is only sellable if the registry and the identity provider bound what it can reach. Terragrunt support and the plan-policy cleanup show the core IaC engine still being maintained rather than neglected for the AI work.

◆ Prediction

Deployment by name is the narrow case; the obvious next step is Intent handling multi-stack changes with policy checks in the loop, and the permission model being extended to describe what the AI specifically is allowed to deploy rather than what a user is.
