Today, we are issuing the thirteenth [Preview release](https://github.com/prisma/prisma2/blob/master/docs/releases.md#preview): `2.0.0-preview-13` (short: `preview-13`).
> **Note**: Due to a German holiday, there won't be a Prisma 2 release next week. The next release `2.0.0-preview-14` will happen in two weeks, on Thursday (October 10th).
A special shoutout to wardpeet whose PR fixed Photon's query engine on Windows 🙏
Breaking changes
This version contains a breaking change in the `_Migrations` table that Lift uses to store the migration history of a project.
Due to that change, you might encounter an error looking similar to this:
thread 'tokio-runtime-worker-0' panicked at 'Deserializing the database migration failed.:
Error("missing field `original_steps`", line: 0, column: 0)', src/libcore/result.rs:999:5
If you see that error, you need to **manually delete the `_Migration` table** from your database as a workaround.
Major changes
Prisma Studio is getting more stable! We were able to fix a number of bugs that impacted the experience when using Studio. Be sure to try the new Studio version out by entering Prisma's development mode with `prisma2 dev` and open the provided Studio endpoint in your browser. You can report Studio bugs [here](https://github.com/prisma/studio/issues).
Another improvement that comes with this release enables you to directly submit detailed error reports whenever the Lift CLI crashes. There won't be any cryptic Rust stracktraces any more in the terminal, instead you'll be shown a dialogue where you can confirm the error report submission.
