What is Flux?

Flux 2.10 swaps static secrets for SPIFFE identity across GitOps controllers and cloud access.

Flux 2.10 is the project's most significant release since the plugin system. It brings SPIFFE workload identity to the GitOps Toolkit, so controllers can authenticate each other with mutual TLS and Flux objects can present short-lived credentials to registries, secret stores and remote clusters. The Event, Alert and Provider APIs also reach stable v1. Around it, the plugin ecosystem keeps filling out with Flux Mirror, while flux9s reached 1.0.

What is Sanity?

Sanity's MCP server now explains failed validations and stops skipping them.

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

Flux 2.10 swaps static secrets for SPIFFE identity across GitOps controllers and cloud access.

◆ Current state

Flux 2.10 is the project's most significant release since the plugin system. It brings SPIFFE workload identity to the GitOps Toolkit, so controllers can authenticate each other with mutual TLS and Flux objects can present short-lived credentials to registries, secret stores and remote clusters. The Event, Alert and Provider APIs also reach stable v1. Around it, the plugin ecosystem keeps filling out with Flux Mirror, while flux9s reached 1.0.

◆ Where it's heading

The arc since 2.9 has two tracks: an extensible CLI that picks up plugins for schema and mirroring, and a steady removal of long-lived credentials. The OpenBao work dropped the bootstrap token, and 2.10 extends that idea to internal traffic and external access. Together they point to a CD layer that owns less configuration and fewer secrets.

◆ Prediction

Expect more SPIFFE integrations and further promotion of object identity into default setups, though the Workload API requirement will slow adoption. The Flux MCP Server is also gaining tools through Flux Operator, so that surface should keep growing.

Sanity's MCP server now explains failed validations and stops skipping them.

◆ Current state

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

◆ Where it's heading

Sanity is making the agent-facing parts dependable: the MCP server is getting the error codes and validation rules a production client needs. Access visibility for tokens and members follows the same push to let teams audit what automated clients do.

◆ Prediction

Expect more MCP server point releases around validation and Knowledge Base commands, and more usage data on tokens and agents in the console.
