• #12618 d920811 Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  workerd	1.20260219.0	1.20260227.0

• #12637 896734d Thanks @​dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  workerd	1.20260227.0	1.20260302.0

• #12602 58a4020 Thanks @​anonrig! - Optimize filesystem operations by using Node.js's throwIfNoEntry: false option

  This reduces the number of system calls made when checking for file existence by avoiding the overhead of throwing and catching errors for missing paths. This is an internal performance optimization with no user-visible behavioral changes.

miniflare@4.20260301.1

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,

Minor Changes

• #12462 f239077 Thanks @​petebacondarwin! - Add Miniflare#purgeCache() method to clear cache entries programmatically

  This allows developers to clear cached data during local development without restarting the Miniflare instance. Useful when working with Workers Sites or any application that uses the Cache API.

  const mf = new Miniflare({
  	/* options */
  });
  // Purge the default cache
  await mf.purgeCache();
  // Purge a specific named cache
  await mf.purgeCache("my-named-cache");

• #12574 527e4f5 Thanks @​emily-shen! - Local explorer: add /query endpoint to introspect sqlite in DOs
