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 Svelte?

SvelteKit 3 reaches release candidate: breaking changes are frozen and the migration path is open

SvelteKit 3 has moved from preview to release candidate, with the team signalling no further breaking changes before stable. Configuration now lives in vite.config.ts instead of svelte.config.js, and an `sv@next migrate sveltekit-3` codemod handles most of the upgrade automatically while flagging the rest as a TODO list. The 2.x line kept shipping through the same period - remote form `submitted`, a relocated `defineEnvVars`, and zero-config error page props.

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.

SvelteKit 3 reaches release candidate: breaking changes are frozen and the migration path is open

◆ Current state

SvelteKit 3 has moved from preview to release candidate, with the team signalling no further breaking changes before stable. Configuration now lives in vite.config.ts instead of svelte.config.js, and an `sv@next migrate sveltekit-3` codemod handles most of the upgrade automatically while flagging the rest as a TODO list. The 2.x line kept shipping through the same period - remote form `submitted`, a relocated `defineEnvVars`, and zero-config error page props.

◆ Where it's heading

The major is arriving as a consolidation rather than a rewrite: most of what lands in 3.0 was previewed in the 2.x line first, so the upgrade cost stays low by design. The centre of gravity has been remote functions and forms for six straight months, and Kit 3 mostly finalises that surface while pruning the configuration story. With breaking changes now frozen, the work shifts from designing the major to getting the ecosystem - adapters, language tools, community plugins - onto it.

◆ Prediction

The stable SvelteKit 3 release is the next milestone, and the team has tied it to RC feedback rather than a date. Expect the monthly digests to fill with adapter and tooling updates catching up to the vite.config.ts requirement before that lands.
