}

• 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.

• compiler: allow isolatedModule: true to have ESM support (#2219) (e101db0), closes #1709
• presets: add 3 new presets to work with ESM (#2207) (c277858)
• allow subclasses of TsJestTransformer to have version checking (#2176) (ca8d7c4)
• support jest 27 (#2171) (9909b9d)

Performance Improvements

• reuse jest file system cache for isolatedModules: false (#2189) (68f446b)

27.0.0-alpha.1 (2020-11-26)

BREAKING CHANGES

• 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.

27.0.0-alpha.0 (2020-11-11)

Code Refactoring

• config: remove support for astTransformers string array (#2129) (1e0b2ce)
• config: remove support for packageJson option (#2128) (05916b9)
• move jest transformer class to package entry (#2122) (5bbfd06)
• config: remove support for tsConfig option (#2127) (3cc9b80)

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
