What is q2?

Ten releases in six days, methodically porting Quarto's surface into a Rust binary.

q2 is the Quarto team's Rust reimplementation of Quarto, shipping as a statically linked single binary with signed release archives and a bundled Quarto Hub MCP server. It is explicitly marked experimental and not production-ready, and it is moving fast — ten releases between 7 and 13 August. The release notes are raw commit logs rather than curated summaries, and reading them shows a consistent programme: work items are investigated, design decisions recorded, tests written red, then implemented in numbered phases, with 'Q1 parity' as the recurring benchmark against the existing Quarto.

What is Semgrep?

Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.

Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

Ten releases in six days, methodically porting Quarto's surface into a Rust binary.

◆ Current state

q2 is the Quarto team's Rust reimplementation of Quarto, shipping as a statically linked single binary with signed release archives and a bundled Quarto Hub MCP server. It is explicitly marked experimental and not production-ready, and it is moving fast — ten releases between 7 and 13 August. The release notes are raw commit logs rather than curated summaries, and reading them shows a consistent programme: work items are investigated, design decisions recorded, tests written red, then implemented in numbered phases, with 'Q1 parity' as the recurring benchmark against the existing Quarto.

◆ Where it's heading

The project is working through the original Quarto's feature surface item by item — project profiles, environment files, shortcodes in metadata, listings, callouts, crossrefs, TOC handling, aliases — while building infrastructure the original lacks, notably a numbered diagnostic catalogue (Q-2-47, Q-14-4 and so on) with a lint that requires a documentation page for every error code. Version 0.18.0's Lua filter support is the load-bearing one, since Quarto's extension ecosystem is written in Lua. Distribution choices point at the same goal: musl-static Linux builds, minisign signatures, no glibc requirement.

◆ Prediction

Expect the parity grind to continue at this cadence, with the remaining high-value Q1 features and diagnostic coverage as the visible queue. The commit logs also show npx distribution planned for the MCP server, which is the nearest thing to a stated roadmap item in these entries.

5.0

Semgrep keeps spending releases on parser breadth and large-repo throughput, not new surface.

◆ Current state

Ten consecutive releases have gone into the engine rather than the product. The recurring shape is a parser refresh (Solidity, Ruby, Dart), a scan-performance change, and a batch of correctness fixes for Pro analysis. Nothing in this window changes what a team buys Semgrep for; it changes how reliably a scan finishes on a large repository.

◆ Where it's heading

The performance work is converging on one problem: very large monorepos. File targeting now batches path filtering across worker domains, rule parsing shards by bytes instead of worker count, and a new Pro memory policy lets a scan trade RAM for skipping on-disk caching. Running alongside it is a quieter thread of trust work, and the 1.173.0 fix for silently dropped targets belongs to it: a file whose path filtering failed appeared in neither the findings nor the skipped list, which is the kind of gap that undermines a scan report more than any missing rule.

◆ Prediction

Expect the parser-refresh-plus-throughput cadence to continue, with the memory policy and the dependency-path output likely graduating out of experimental once large-repo users report back on them.
