 This guide details the changes and how to change your code to migrate to Cypress
 version 13.0.

+### Cypress Cloud Test Replay
+
+[Test Replay](https://docs.cypress.io/guides/overview/why-cypress) is enabled by default in `v13.0` of the Cypress App.
+
+You may need to allowlist `capture.cypress.io` if you work with a strict VPN. See our FAQ section about [VPN subdomain allowlisting](/faq/questions/cloud-faq#Im-working-with-a-restrictive-VPN-Which-subdomains-do-I-have-to-allow-on-my-VPN-for-Cypress-Cloud-to-work-properly).
+
+You can [opt out](https://docs.cypress.io/guides/overview/why-cypress) of this feature in Cloud project-level settings.

+### Video updates
+
+#### `video` is set to `false` by default
+
+You can continue recording video, by passing `video: true`, if you want video locally or you want video for some other reason, like in non-Chromium browsers where [Test Replay](https://docs.cypress.io/guides/overview/why-cypress) is not available.
+
+:::cypress-config-example
+
+```ts
+{
+  video: true
+}
+```
+
+:::
+
+#### `videoUploadOnPasses` configuration option has been removed
+
+Most users used `videoUploadOnPasses` as a way to skip the time to compress and upload videos to the Cloud. Since we're turning off `videoCompression` by default, this configuration option does not offer the time saving value that it once would.
+
+If you want to prevent a passing test from uploading to the Cloud, we recommend deleting the video using our [guide with code examples to discard captured video of passing tests](/guides/guides/screenshots-and-videos#Control-which-videos-to-keep-and-upload-to-Cypress-Cloud).
+
+#### `videoCompression` is set to `false` by default
+
+Cypress has the capability to compress recorded videos after a run to reduce the video file size. By default, compression is now turned off. This results in a reduced run time by removing the time to compress the video, a larger video file size and better video quality.
+
+You can enable this with the `videoCompression` [configuration](/guides/references/configuration#Videos) option if you'd like to reduce the video file size for any reason. This will also reduce the video quality and take slightly longer to process and complete the run.
+
+:::cypress-config-example
+
+```ts
+{
+  // value can be true/false -or- an integer between 0 and 51
+  videoCompression: true,
+}
+```
+
