The company will provide standard MTC issuance at no cost. MTCs batch certificates into an append-only Merkle tree to address the scaling issues of post-quantum cryptography, which can increase log storage requirements by 40 times. Cloudflare successfully tested the technology with Chrome, serving billions of MTCs and finding that median performance was 9% faster than classical signature chains.

                                    AWS has introduced metadata pre-filtering for Amazon S3 Vectors to improve recall on filtered queries. The feature evaluates metadata filters before running a similarity search and supports up to 100 filter constraints per query. On highly selective filters, pre-filtering returns up to five times more matching vectors than previous methods. It is available immediately at no additional cost and works on existing indexes without requiring data re-ingestion.
                                &lt;/span&gt;

                                    Cloudflare has rearchitected its Containers service to handle agent workloads, allowing code to select the image and instance type at runtime. The update introduces a new scheduling policy that starts containers six times faster, with median startup times falling from over four seconds to 648 milliseconds in independent benchmarks. A filesystem snapshots feature is also available in public beta to let workspaces save and restore their state.

                                    Gartner forecasts that 40% of companies will downgrade autonomous AI agents by 2027 due to governance gaps found after production incidents. Google's DORA 2025 research found that 90% of organizations already use an internal platform, and 76% have dedicated teams for them. Broadcom research shows 97% of IT leaders believe some public cloud spending is wasted, with cost now exceeding security as the primary concern.
                                &lt;/span&gt;

The system ran 1,107 attempts across six attack categories and recorded 49 findings that required human review. Cloudflare used these results to release new detections for SSRF attacks and improve an existing cloud metadata rule.

It runs as a native desktop app on macOS, Windows, and Linux, or via Docker and web deployments, without requiring Java, Python, or bundled Chromium. The tool includes an AI assistant that generates SQL from natural language and an MCP server that lets coding agents query databases.

It renders video by seeking frames in headless Chrome to ensure the same input always produces the same output.

Testing across four models showed accuracy gains up to 21.8 points alongside 73% fewer input tokens and 40% fewer tool calls.
