What is Auth0?

Auth0 is replacing its legacy configuration surfaces one at a time, and shipping NIST defaults to new tenants only.

Flexible Password Policy reaches general availability, collapsing five legacy password fields into a single password_options object that covers composition, history, dictionary blocking against 10,000- or 100,000-word lists, and profile-data matching. New database connections have defaulted to it since July with a 15-character minimum aligned to current NIST guidance, while existing connections keep their configuration until an operator migrates them. That sits alongside a fortnight of delegation and administration work: Custom Token Exchange session delegation, Custom Prompts finally applying to social and enterprise connections, Google Workspace group sync reaching GA, organization filtering, and a command palette.

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.

Auth0 is replacing its legacy configuration surfaces one at a time, and shipping NIST defaults to new tenants only.

◆ Current state

Flexible Password Policy reaches general availability, collapsing five legacy password fields into a single password_options object that covers composition, history, dictionary blocking against 10,000- or 100,000-word lists, and profile-data matching. New database connections have defaulted to it since July with a 15-character minimum aligned to current NIST guidance, while existing connections keep their configuration until an operator migrates them. That sits alongside a fortnight of delegation and administration work: Custom Token Exchange session delegation, Custom Prompts finally applying to social and enterprise connections, Google Workspace group sync reaching GA, organization filtering, and a command palette.

◆ Where it's heading

Two patterns run through this window. Auth0 is retiring ad-hoc configuration in favor of structured objects and then changing defaults only for new tenants — legacy password policies stay supported with no end-of-life date, so the migration is carried by new-connection defaults rather than forced deprecation. Alongside that, the delegation model established by Custom Token Exchange keeps widening, and the recurring theme in the smaller releases is closing gaps where a setting appeared to apply everywhere but did not.

◆ Prediction

Expect the same treatment applied to another legacy configuration surface — a single structured object, GA, and new-tenant defaults with the old fields left supported indefinitely. Whether Auth0 ever sets an end-of-life for the legacy password fields is explicitly left open in this release.

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.
