New Asia-Pacific location hints: apac-ne and apac-se
Durable Objects now supports two new location hints for Northeast and Southeast Asia-Pacific, giving you finer-grained control within the `apac` region.
Outbound connections keep Durable Objects alive
Active outbound TCP sockets and outbound WebSocket connections now prevent a Durable Object from being evicted while the connection is open.
Temporary accounts for AI agent deployments
Deploy Workers from AI agents with `wrangler deploy --temporary`, then claim the temporary account within 60 minutes.
Cloudflare identity provider is now the default for new accounts
New Zero Trust organizations get the Cloudflare identity provider as their default login method instead of one-time PIN.
Create PlanetScale Postgres and MySQL databases, billed to your Cloudflare account
Cloudflare partners with PlanetScale to provide Postgres and MySQL databases for Workers applications with unified billing through your Cloudflare account.
