What is Auth0?

Auth0 hands tenants a throttle on their own noisy apps

Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.

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.

Auth0 hands tenants a throttle on their own noisy apps

◆ Current state

Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.

◆ Where it's heading

Two threads dominate. One is agent and delegation infrastructure — Agents as Principal, Token Vault Privileged Worker, Custom Token Exchange session delegation — all still in Early Access. The other is tenant self-service: rate limits, blocklists, organization search and roles, global search. Auth0 is systematically converting things that required support intervention into API-configurable policy.

◆ Prediction

The Early Access items now stacking up, particularly the agent-identity pieces, are the obvious GA candidates next, following the Flexible Password Policy path from Early Access to general availability.

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.
