Drupal 10 will be supported until the release of Drupal 12 in mid-late 2026
Beginning with Drupal 10, a new Drupal major version will be released every two years in even years (2022, 2024, etc.). 

The fifth and final feature release of Drupal 9 brings a stable CKEditor 5 module, a command line theme generator, and helps prepare for your update to Drupal 10. 
Bugfixes will be provided for Drupal 9.5 until June 2023 and security fixes will be provided until November 2023.

Drupal 10 will be a refined version of Drupal 9 including all the goodies from all initiatives. It will include Olivero, Claro, all the work from the Automated Updates Initiative, Bug Smash, Easy Out-of-the-box, Decoupled Menus, and the Project Browser if we have one in time.

I always wonder, does Drupal integrate only with CKEditor for its long text editing needs...

so, I just found a few text editors that should be tested and checked

I will try to give some overview on them, please feel free to comment and give to community of your own experience

In 2023, IRONSTAR received 829 responses from 96 different countries. They had responses from places like Ethiopia, Albania, Costa Rica, Vietnam, and Cuba, as well as many of the countries you’d expect to see.

A Digital Experience Platform (DXP) is simply a platform for providing rich cross-channel personalized digital experiences.

In Drupal 10.1, completely rewritten aggregation generation logic solves both of these issues.

Aggregates are now built by a dedicated route, with the main request only responsible for generating the aggregate URL based on libraries, theme, language, and grouping logic.
