Kinde broadens its auth surface to passkeys while building out billing and B2B controls.
Kinde is shipping monthly feature roundups that consistently advance three fronts: authentication breadth, self-serve billing, and enterprise/B2B controls. The latest release adds passkeys (WebAuthn/FIDO2) for passwordless sign-in, the clearest capability jump in the window. Recent months also brought WhatsApp verification, IdP-initiated SAML, invite controls, and an MCP server for AI agents — a developer-focused auth platform widening on every axis.
Prometheus ships steady LTS releases with security discipline and deepening PromQL
Prometheus is in mature-maintenance mode, running parallel release trains: the 3.5 and 3.11 LTS lines get prompt security backports alongside the fast-moving 3.12/3.13 branch. The 3.13.0 LTS release bundles native-histogram advances, experimental PromQL duration functions, and TSDB performance work, while a steady drumbeat of CVE fixes shows an active security-response process.

Recent months also brought WhatsApp verification, IdP-initiated SAML, invite controls, and an MCP server for AI agents — a developer-focused auth platform widening on every axis.
Kinde is racing to close the feature gap with incumbent auth providers while differentiating on developer experience and built-in monetization. Authentication is going passwordless and omni-channel (passkeys, WhatsApp, SAML), billing is becoming a first-class self-serve product, and the MCP server stakes an early claim on auth for AI agents. The direction is a single platform that handles identity and billing together.
Expect continued enterprise hardening — likely deeper SSO/SCIM and organization-level controls — paired with more billing automation, as Kinde pushes up-market into B2B.

The center of gravity is PromQL expressiveness (duration expressions, start-timestamp-aware rate/increase, smoothed and anchored functions) and native histograms, both landing incrementally behind feature flags. Service-discovery breadth keeps widening (DigitalOcean, Outscale, AWS refinements). Security handling, from plaintext-secret leaks to XSS to credential forwarding on redirect, is treated as first-class and fanned out across every supported line.
Expect the experimental PromQL and native-histogram features to graduate toward stable in an upcoming minor, and continued rapid security patching across the 3.5, 3.11, and 3.13 LTS lines.
