Hey <!everyone> :v: :prisma-cool: We just release...
# prisma-whats-new
Hey <!everyone> ✌️ prisma cool We just released Prisma v2.12.0 with lots of improvements! prisma rainbow  In this version, we also took some time to clean up our codebase and the Prisma Client API a little bit, partially resulting in breaking changes  🧹 🖥️ Standalone Prisma Studio app for macOS We have repackaged Prisma Studio to work also as a standalone macOS application, this enables you to run Studio with just a double click and without opening your terminal. You can download the 
 from the Studio release page. Support for more platforms (Windows and Linux) will follow soon! 🦿 Prisma codemods help upgrading your codebase With today's release, we took the opportunity to cleanup some rough edges in the Prisma Client API which partially results in breaking changes. To help you with upgrading your codebase to 2.12.0, we're introducing `@prisma/codemods`. The 
 package provides a powerful CLI that scans your codebase and automatically updates the code to the new API calls from the provided version. The upgrade workflow looks like this:
Copy code
cd my-app
npm install @prisma/cli --save-dev
npm install @prisma/client
npx @prisma/codemods update-2.12 ./
🤓 Microsoft SQL Server now supports native database types (Preview) Hot off the presses: You can now use native database types with Microsoft SQL Server by specifying both the 
 feature flags in your Prisma schema:
Copy code
generator js {
  provider        = "prisma-client-js"
  previewFeatures = ["microsoftSqlServer", "nativeTypes"]

datasource ms {
  provider = "sqlserver"
  url      = env("DATABASE_URL")

model User {
  id   BigInt  @id @default(autoincrement()) @ms.BigInt
  name String? @ms.VarChar(255)
⚠️ Breaking changes and deprecations The cleanup in this release comes with a number of breaking changes: • Removal of deprecated non-
 methods: Some top-level Prisma Client methods have been prefixed with a 
 a few releases ago. While the non-
 versions of these methods still continued to work, we're finally removing them in this release, meaning you now need to make sure you're adfding the 
 (e.g. for calls like 
). • 1-1-relations must now have an optional side: The Prisma schema used to allow 1-1-relations that were required on both sides. This is not allowed any more as of this release. The fastest way to update your existing 1-1-relations to this new requirement is by running 
npx prisma introspect
. • Fix how data for 
 fields is stored: The way how fields of type 
 have been stored in previous releases had a number of issues. This release fixes these issues: Previously, JSON arrays were stored as a string inside a your database's 
 column. Now, they are properly encoded JSON arrays in the database. The following changes are not yet breaking, but indicate a future breaking change via deprecation: • 
 is renamed to 
 to give more clarity about the behaviour of the method • Exported types from 
 are now under a 
 namespace Learn all about the breaking changes in the release notes. 🤩 Upcoming Prisma Migrate Preview Release We’ve got a Preview release of Prisma Migrate nearing up with a large set of changes.
