Patch Changes

• #16139 2d1d563 Thanks @cpojer! - Update esbuild to 0.28.2

  Align esbuild dependency with tooling using the latest 0.28 patch so package managers can share one installation instead of downloading a second native binary.

• #15939 e6f7663 Thanks @00200200! - Fix local Workflows hitting the timer quota on long runs

  Long local workflows no longer fail from timer exhaustion. Step timeout timers, sleep, waitForEvent, and grace-period waits now cancel their underlying timers when finished or aborted, instead of remaining until their original deadlines.

• #16098 fe607f9 Thanks @dependabot! - Update dependencies of "miniflare", "wrangler"

  The following dependency versions have been updated:

  Dependency	From	To
  sharp	0.35.4	0.35.5

• #15879 8de6b3c Thanks @dawNotPoi! - Stop Hyperdrive proxy listeners from accumulating across local development reloads

  Miniflare now reuses a listener when a Hyperdrive binding keeps the same target and closes listeners no longer used after a configuration update. Changing or removing a binding, including switching to sslmode=disable, no longer leaves stale listening ports in wrangler dev.

• #16106 ae29445 Thanks @Arthur031221! - Fix the local Images binding and cf.image transforms ignoring EXIF orientation. Previously, photos stored with an EXIF orientation flag (e.g. phone portrait photos, stored as landscape pixels plus a rotation flag) came back sideways from local transforms, while the production Images binding auto-orients them. Local dev now bakes the EXIF rotation into the pixels before applying transforms, matching production behavior.

• #16041 cc8e969 Thanks @Shubham-Padkonde! - Support single-object R2 deletion through the Local Explorer API

  Local R2 clients can now delete an object with DELETE /r2/buckets/{bucket_name}/objects/{object_key} instead of having to use the bulk-delete endpoint. The route handles path-like keys and uses the same storage service as other local R2 operations.

• #16144 417b186 Thanks @cpojer! - Honor the source-map setting in release builds

  Omit Miniflare's own source maps when building with SOURCEMAPS=false, reducing the installed package size. Development builds continue to include self-contained source maps, and source maps for user Workers remain supported.
