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 SimpleSAMLphp?

Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.

SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.

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.

S5.0

Two maintenance branches, patched in lockstep, with release notes that say nothing but a checksum.

◆ Current state

SimpleSAMLphp is running parallel 2.4 and 2.5 maintenance branches and patching both on the same day whenever a fix lands. The August releases are a coordinated security drop across the 2.5 line plus a 2.4 bugfix a day earlier. Release bodies carry no changelog text at all — just a download link, upgrade-notes pointer, and SHA256 checksums, so the feed tells operators when to patch but never what changed.

◆ Where it's heading

This is pure maintenance cadence, not product development. The pattern across the last ten releases is consistent: security issues get simultaneous twin tags on both supported branches, everything else lands as branch-local bugfix points. The only release in the window that documented its own content was v2.4.6/v2.5.1 in May, which listed three GHSA advisories.

◆ Prediction

Expect the next tags to continue the twin-branch pattern — a paired 2.4.x and 2.5.x whenever an advisory lands, with content again deferred to the external changelog.
