Minor Changes

• #12649 35b2c56 Thanks @gabivlj! - Add experimental support for containers to workers communication with interceptOutboundHttp

  This feature is experimental and requires adding the "experimental" compatibility flag to your Wrangler configuration.

• #10153 5f7aaf2 Thanks @mglewis! - Add Hosted Images CRUD operations to Images binding.

  This is an experimental API that only works locally for the moment.

• #12622 bf9cb3d Thanks @LuisDuarte1! - Add configurable step limits for Workflows

  You can now set a maximum number of steps for a Workflow instance via the limits.steps configuration in your Wrangler config. When a Workflow instance exceeds this limit, it will fail with an error indicating the limit was reached.

  // wrangler.jsonc
  {
  	"workflows": [
  		{
  			"binding": "MY_WORKFLOW",
  			"name": "my-workflow",
  			"class_name": "MyWorkflow",
  			"limits": {
  				"steps": 5000,
  			},
  		},
  	],
  }

  The steps value must be an integer between 1 and 25,000. If not specified, the default limit of 10,000 steps is used. Step limits are also enforced in local development via wrangler dev.
