30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Full Changelog: https://github.com/jestjs/jest/blob/main/CHANGELOG.md

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Full Changelog: https://github.com/jestjs/jest/blob/main/CHANGELOG.md

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Full Changelog: https://github.com/jestjs/jest/blob/main/CHANGELOG.md

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Security Advisories 🚨

🚨 Inefficient Regular Expression Complexity in chalk/ansi-regex

ansi-regex is vulnerable to Inefficient Regular Expression Complexity which could lead to a denial of service when parsing invalid ANSI escape codes.

Proof of Concept

import ansiRegex from 'ansi-regex';
for(var i = 1; i <= 50000; i++) {
    var time = Date.now();
    var attack_str = "\u001B["+";".repeat(i*10000);
    ansiRegex().test(attack_str)
    var time_cost = Date.now() - time;
    console.log("attack_str.length: " + attack_str.length + ": " + time_cost+" ms")
}

The ReDOS is mainly due to the sub-patterns [[\\]()#;?]* and (?:;[-a-zA-Z\\d\\/#&.:=?%@~_]*)*

Release Notes

6.2.2

6.2.0

  • Support colon separated parameters to control sequences (#62) df7d75f

v6.1.0...v6.2.0

6.1.0

  • Match cursorSave and cursorRestore escape codes (#45) 02fa893
  • Fix: Handle all valid ST characters (#58) 9cba40d

v6.0.1...v6.1.0

6.0.1

Fixes

  • Fix ReDoS in certain cases (#37)
    You are only really affected if you run the regex on untrusted user input in a server context, which it's very unlikely anyone is doing, since this regex is mainly used in command-line tools.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Security Advisories 🚨

🚨 error-ex@1.3.3 contains malware after npm account takeover

Impact

On 8 September 2025, an npm publishing account for error-ex was taken over after a phishing attack. Version 1.3.3 was published, functionally identical to the previous patch version, but with a malware payload added attempting to redirect cryptocurrency transactions to the attacker's own addresses from within browser environments.

Local environments, server environments, command line applications, etc. are not affected. If the package was used in a browser context (e.g. a direct <script> inclusion, or via a bundling tool such as Babel, Rollup, Vite, Next.js, etc.) there is a chance the malware still exists and such bundles will need to be rebuilt.

The malware seemingly only targets cryptocurrency transactions and wallets such as MetaMask. See references below for more information on the payload.

Patches

npm removed the offending package from the registry over the course of the day on 8 September, preventing further downloads from npm proper.

On 13 September, the package owner published new patch versions to help cache-bust those using private registries who might still have the compromised version cached. This version is functionally identical to the previously known-good version, published as a patch version bump above the compromised version.

Users should update to the latest patch version, completely remove their node_modules directory, clean their package manager's global cache, and rebuild any browser bundles from scratch.

Those operating private registries or registry mirrors should purge the offending versions from any caches.

Point of Contact

In the event suspicious behavior is still observed for the package listed in this security advisory after performing all of the above cleaning operations (see Patches above), please reach out via one of the following channels of communication:

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Full Changelog: https://github.com/jestjs/jest/blob/main/CHANGELOG.md

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Full Changelog: https://github.com/jestjs/jest/blob/main/CHANGELOG.md

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Full Changelog: https://github.com/jestjs/jest/blob/main/CHANGELOG.md

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.
