+## Version 1.50
+
+### Breaking
+
+* [`method: LocatorAssertions.toBeEditable`] and [`method: Locator.isEditable`] now throw if the target element is not `<input>`, `<select>`, or a number of other editable elements.
+* Option [`property: TestConfig.updateSnapshots`] now updates all snapshots when set to `all`, rather than only the failed/changed snapshots. Use the new enum `changed` to keep the old functionality of only updating the changed snapshots.
+
+### Test runner
+
+* New option [`option: Test.step.timeout`] allows specifying a maximum run time for an individual test step. A timed-out step will fail the execution of the test.
+* New method [`method: Test.step.skip`] to disable execution of a test step.
+* Expanded [`method: LocatorAssertions.toMatchAriaSnapshot#2`] to allow storing of aria snapshots in separate YAML files.
+* Added method [`method: LocatorAssertions.toHaveAccessibleErrorMessage`] to assert the Locator points to an element with a given [aria errormessage](https://w3c.github.io/aria/#aria-errormessage).
+* Option [`property: TestConfig.updateSnapshots`] added the configuration enum `changed`. `changed` updates only the snapshots that have changed, whereas `all` now updates all snapshots, regardless of whether there are any differences.
+* New option [`property: TestConfig.updateSourceMethod`] defines the way source code is updated when [`property: TestConfig.updateSnapshots`] is configured.
+* Option [`property: TestConfig.webServer`] added a `gracefulShutdown` field for specifying a process kill signal other than the default `SIGKILL`.
+
+### Reporter
+
+* Exposed [`property: TestStep.attachments`] from the reporter API to allow retrieval of all attachments created by that step.
+* Updated default HTML reporter to improve display of attachments.
+
+### UI updates
+
+* New button for picking elements to produce aria snapshots.
+* Additional details (such as keys pressed) are now displayed alongside action API calls in traces.
+* Display of `canvas` content in traces is error-prone. Display is now disabled by default, and can be enabled via the `Display canvas content` UI setting.
+* `Call` and `Network` panels now display additional time information.
