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) (1fecf7f)
• add exports field to package.json, see https://nodejs.org/api/packages.html#packages_package_entry_points (#​2467) (d3aba3e)
• 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'],
         }
      }

• 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.
