Bun 1.2.19 Adds Isolated Installs for Better Monorepo Support
Bun 1.2.19 introduces isolated installs for smoother monorepo workflows, along with performance boosts, new tooling, and key compatibility fixes.
CKEditor 4 was launched in 2012 and reached its End of Life (EOL) on June 30, 2023.
A special edition, CKEditor 4 LTS ("Long Term Support"), is available under commercial terms ("Extended Support Model") for anyone looking to extend the coverage of security updates and critical bug fixes.
With CKEditor 4 LTS, security updates and critical bug fixes are guaranteed until December 2028.
After June 30, 2023 the master
version of the LICENSE.md file changed to reflect the license of CKEditor 4 LTS available under the Extended Support Model.
All future versions of CKEditor 4 (4.23.0-lts and above) are released as CKEditor 4 LTS distributions and require a license key.
The CKEditor 4 Nuget packages are tagged as 4.23.* without the -lts
suffix, to keep it consistent with NPM versioning guidelines. Note that the version 4.23.0 and above are the LTS versions of the editor.
You may continue using CKEditor 4.22.* and below under the open source license terms. Please note, however, that the open source version no longer comes with any security updates, so your application will be at risk.
In order to install the open source version of CKEditor 4, use versions 4.22.1 and below. CKEditor 4.22.1 was the last version of CKEditor 4 available under the open source license terms.
CKEditor 5 is a great new editor with lots of exciting features.
Before upgrading, please be aware of the following changes:
You may continue using CKEditor 4.22.* (or below). The license terms of the older CKEditor 4 versions have not changed. However, please note that by using software that is no longer maintained, you are introducing a security risk to your application.
If you are not ready to replace CKEditor 4 in your application yet, you may continue using CKEditor 4 until December 2028. CKEditor 4 LTS, available under the "Extended Support Model", will ship all important security updates and critical bug fixes, providing an interrupted editing experience for your end users. Please note that this version of CKEditor 4 is available only under a special agreement and requires a license key.
