+# v1.0.2
+
+This release fixes a runtime/package drift that could make local Stagehand startup fail after installing the Laravel package.
+
+The Laravel package had learned to launch Stagehand with newer navigation and request-limit flags, but the default installer could still fetch the older `v1.0.1` Stagehand binary. That binary did not know those flags, so it exited before serving. `v1.0.2` aligns the package and runtime surfaces and adds a compatibility guard so this class of mismatch fails early with a clear installer error instead of reaching end users as a broken local runtime.
+
+## Fixed
+
+- The Laravel installer now validates downloaded Stagehand binaries before accepting them.
+- Stale Stagehand binaries that do not expose required serve flags are rejected and removed.
+- The default Stagehand runtime release now points at `v1.0.2`, matching the package command surface.
+- Windows binary resolution now handles absolute drive-letter paths and runnable `.exe`, `.cmd`, and `.bat` files correctly.
+- Stagehand Chromium profiles are namespaced per runtime process, so stale browser children from a crashed or force-stopped runtime cannot lock the next process out of local PDF rendering.
+- Browser-pool startup no longer returns a fresh lease with a cancelled browser context after acquire-timeout cleanup races.
+
+## For Laravel Users
+
+If you use embedded local rendering, run the installer again after upgrading:
+
+```bash
+php artisan canio:runtime:install
+```
+
+The installer will fetch the `v1.0.2` Stagehand binary for your platform and verify that it supports the flags required by this package.
+
+## Release Assets
+
+This release publishes Stagehand binaries for Linux, macOS, and Windows on amd64 and arm64, plus `checksums.txt`.
