+# Improvements

+## Updates Zod version from v3 to v4
+
+Upgrades the zod dependency from v3 to v4 while remaining backward compatible with previous versions.
+
+### Deprecated `.strict()` method has been omitted from modernisation steps 
+
+`.strict()` is the only functionality to be skipped when modernising the code utilising zod. This is because the rewrite 
+of drizzle-kit in #4439 may mean this work is discarded in later releases. `.strict()` requires quite a bit of work to
+align it with the v4 API and doing so will also void backward compatibility.

+# Improvements
+
+## Migrates zod to v4
+
+The following impacts have been addressed to support the migration to zod v4 for the packages: drizzle-zod and drizzle-kit
+
+### Changes
+
+**drizzle-zod** (v0.8.0)
+ - peerDependencies: `"zod": ">=4.0.0"`
+ - devDependencies: `"zod": "^4.1.1"`
+ - Files: drizzle-zod/package.json:68,79
+
+**drizzle-kit** (v0.32.0)
+ - devDependencies: `"zod": "^4.1.12"`
+ - Files: drizzle-kit/package.json:116
+ - Heavy internal usage in validation and serialization modules
+
+**drizzle-orm** (v0.40.0)
+ - devDependencies: `"zod": "^4.0.0"`
+ - Files: drizzle-orm/package.json:204
+
+**integration-tests**
+ - dependencies: `"zod": "^4.1.1"`
+ - Files: integration-tests/package.json:79
+
+**examples/libsql**
+ - dependencies: `"zod": "^4.1.1"`
+ - Files: examples/libsql/package.json:22
+ - Updated Dependencies: `@hono/zod-validator: ^0.4.1`, `znv: ^0.5.0`
+
+### Out of date package-lock.json regeneration
+
+These examples had zod 3.x references in their package-lock.json files from transitive dependencies. All lock files have been regenerated.
+
+Note: These examples don't directly depend on zod. The old zod 3.x references were from transitive dependencies through drizzle-kit. After regenerating lock files, they now pull the latest drizzle-kit which uses Zod 4.x.
+
+**examples/pg-proxy**
+ - package-lock.json
+
+**examples/mysql-proxy**
+ - package-lock.json
+
+**examples/better-sqlite3**
+ - package-lock.json
+
+**examples/aws-lambda**
+ - package-lock.json
