Minor Changes

• #​14586 5a56dda Thanks @​emily-shen! - Breaking change: Remove several options from the miniflare override options

  The following options have been removed from the miniflare override options, as they were not intended to be exposed, were not functional, or have been superseded by other options:

  • wrappedBindings
  • cacheWarnUsage
  • fetchMock: you should use outboundService instead
  • containerEngine: containers were not supported in vitest-pool-workers. Consider using createTestHarness() instead if you want to test against actual containers.

  Additionally, cache has been deprecated and renamed to cacheAPI, but cache remains functional.

Patch Changes

• #​14586 5a56dda Thanks @​emily-shen! - Preserve the deprecated Miniflare cache option

  Vitest configurations using cache continue to work after the internal Miniflare v5 upgrade. The option is translated to cacheAPI; new configurations should use cacheAPI directly.

• #​14586 5a56dda Thanks @​emily-shen! - Stop enabling Miniflare's removed unsafeStickyBlobs option

  The pool no longer sets the unsafeStickyBlobs Miniflare option, which has been removed. This option was only needed for the Durable Object isolated storage feature that was dropped in 0.13.0, so there is no change in behaviour.

Minor Changes

• #​14879 e6480e3 Thanks @​dmmulroy! - Add a verbose option to cloudflareTest() and cloudflarePool() configuration

  Set verbose: false to suppress verbose workerd runtime logs, such as caught Durable Object RPC errors. The option defaults to true to preserve existing output.

Patch Changes

• #​14821 edc203e Thanks @​mishushakov! - Ignore workerd's disconnected: peer disconnected without gracefully ending TLS session exception logs

  When tests make real fetch() calls to external TLS endpoints, servers and load balancers routinely close idle keepalive connections without sending a TLS close_notify. No request fails — the connection is idle — but workerd logs a kj/compat/tls.c++ exception with a full stack trace each time, flooding otherwise green test runs. This is the TLS sibling of the disconnected: ... messages already in the ignore list, so filter it the same way.
