## BREAKING CHANGES
* By default, `ts-jest` will use `sourceMap` option from your `tsconfig`. If users want to have sourcemap on, they need to set `sourceMap: true` in `tsconfig`.
* follow Jest support Node engines ([#2478](https://github.com/kulshekhar/ts-jest/pull/2478)) ([1fecf7f](https://github.com/kulshekhar/ts-jest/commit/1fecf7ff92a5f1a0cc6ea1d27026f9f54a3d5ead))
* add `exports` field to `package.json`, see https://nodejs.org/api/packages.html#packages_package_entry_points ([#2467](https://github.com/kulshekhar/ts-jest/pull/2467)) ([d3aba3e](https://github.com/kulshekhar/ts-jest/commit/d3aba3e103f85b3a42d0e2ecaea9d3457917319e))
* `ts-jest` custom AST transformer function signature has changed to
```
import type { TsCompilerInstance } from 'ts-jest/dist/types'
export function factory(compilerInstance: TsCompilerInstance) {
//...
}
```
* One is currently using `pathRegex` should use `exclude` with `glob` patterns.
* If one currently relies on type check for `js` files, please set `checkJs: true` in your tsconfig.
* Now both `isolatedModules: true` and `isolatedModule: false` codes are in one single class `TsCompiler` which is an instance created in `TsJestCompiler` based on config option `compiler` with value `typescript` or `ttypescript`.
* **config:** `packageJson` config option is not used in internal `ts-jest` so this option is now removed.
* **config:** One is defining ast transformers in `jest.config.js`/`package.json` should change to
```
// jest.config.js
module.exports = {
//...
globals: {
'ts-jest': {
astTransformers: {
before: ['your_before_transformer_path'],
after: ['your_after_transformer_path'],
afterDeclarations: ['your_afterDeclarations_transformer_path'],
}
}
}
}
```
or
```
// package.json
{
"jest": {
"globals": {
"ts-jest": {
"astTransformers": {
"before": ["your_before_transformer_path"],
"after": ["your_after_transformer_path"],
"afterDeclarations": ["your_afterDeclarations_transformer_path"]
}
}
}
}
}
```
* One currently refers type in `jest.config.js`
```
/** @typedef {import('ts-jest')} */
module.exports = {
//...
}
```
should change to
```
/** @typedef {import('ts-jest/dist/types')} */
module.exports = {
//...
}
```
* Remove possibilities to import `mocked`, `createJestPreset`, `pathsToModuleNameMapper` from package entry. One should change to
```
import { mocked, createJestPreset, pathsToModuleNameMapper } from 'ts-jest/utils'
```
* **config:** One currently uses `tsConfig` should change to `tsconfig` in your `jest.config.js` or `package.json`.

### BREAKING CHANGES
* **config:** `packageJson` config option is not used in internal `ts-jest` so this option is now removed
* **config:** One is defining ast transformers in `jest.config.js`/`package.json` should change to
```
// jest.config.js
module.exports = {
//...
globals: {
'ts-jest': {
astTransformers: {
before: ['your_before_transformer_path'],
after: ['your_after_transformer_path'],
afterDeclarations: ['your_afterDeclarations_transformer_path'],
}
}
}
}
```
or
```
// package.json
{
"jest": {
"globals": {
"ts-jest": {
"astTransformers": {
"before": ["your_before_transformer_path"],
"after": ["your_after_transformer_path"],
"afterDeclarations": ["your_afterDeclarations_transformer_path"]
}
}
}
}
}
```
- One currently refers type in `jest.config.js`
```
/** @typedef {import('ts-jest')} */
module.exports = {
//...
}
```
should change to
```
/** @typedef {import('ts-jest/dist/types')} */
module.exports = {
//...
}
```
- Remove possibilities to import `mocked`, `createJestPreset`, `pathsToModuleNameMapper` from package entry. One should change to
```
import { mocked, createJestPreset, pathsToModuleNameMapper` } from 'ts-jest/utils'
```
* **config:** One currently uses `tsConfig` should change to `tsconfig` in your `jest.config.js` or `package.json`
