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 Groonga?

A veteran full-text engine quietly growing embedding functions alongside its string toolkit.

Groonga ships small, precise releases roughly monthly, each documenting changes with runnable examples and crediting the reporter by name. The 16.0 line opened in February 2026 with an annual major release that deliberately carried no backward-incompatible changes. Recent work splits between conventional search functions — a new string_truncate(), vector support in between() — and a language model path where language_model_vectorize() consumes GGUF models from HuggingFace and TokenLanguageModelKNN handles query and passage prefixes. Contributor counts per release run to a handful of people.

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.

A veteran full-text engine quietly growing embedding functions alongside its string toolkit.

◆ Current state

Groonga ships small, precise releases roughly monthly, each documenting changes with runnable examples and crediting the reporter by name. The 16.0 line opened in February 2026 with an annual major release that deliberately carried no backward-incompatible changes. Recent work splits between conventional search functions — a new string_truncate(), vector support in between() — and a language model path where language_model_vectorize() consumes GGUF models from HuggingFace and TokenLanguageModelKNN handles query and passage prefixes. Contributor counts per release run to a handful of people.

◆ Where it's heading

The embedding functions are the notable thread. A search engine of this vintage adding model-backed vectorization as ordinary functions, callable from the same query language as everything else, is positioning for hybrid retrieval without a separate vector store in the stack. The rest of the cadence is characteristic of the project: careful compatibility work, Windows packaging problems chased across multiple releases, and build-system fixes contributed by downstream packagers.

◆ Prediction

Expect indexing support for the vector cases that currently work without an index — between() on vectors is explicitly flagged as unindexed — and further options on the language model functions. The project's no-breaking-changes stance on major releases suggests continuity rather than a rearchitecture.
