Introducing iceberg-js: A JavaScript Client for Apache Iceberg
Supabase introduced iceberg-js, a vendor-agnostic JavaScript client for the Apache Iceberg REST Catalog API, enabling type-safe catalog management.
Workers - Python cold start improvements
Python Workers now feature improved cold start performance, reducing initialization time for new Worker instances. This improvement is particularly noticeable for Workers with larger dependency sets or complex initialization logic. Every time you deploy a Python Worker, a memory snapshot is captured after the top level of the Worker is executed.
Workers - Easy Python package management with Pywrangler
We are introducing a brand new tool called Pywrangler, which simplifies package management in Python Workers by automatically installing Workers-compatible Python packages into your project.
Workers - Wrangler config is optional when using Vite plugin
When using the Cloudflare Vite plugin to build and deploy Workers, a Wrangler configuration file is now optional for assets-only (static) sites. If no wrangler.toml , wrangler.json , or wrangler.jsonc file is found, the plugin generates sensible defaults for an assets-only site.
Workers - Configure Workers programmatically using the Vite plugin
The Cloudflare Vite plugin now supports programmatic configuration of Workers without a Wrangler configuration file. You can use the config option to define Worker settings directly in your Vite configuration, or to modify existing configuration loaded from a Wrangler config file.
View predictions in Cloud Provider Observability
You can now view machine learning predictions for drilldown instances of preconfigured dashboards in Cloud Provider Observability using the Predict button. Predictions help you ensure resources are available during spikes in usage, as well as help you decrease the amount of resources due to over provisioning.
