Updated Eclipse Platform (4.14) & CDT 9.10


2020-04 is based on the updated Eclipse Platform (4.14) & CDT 9.10 which includes new features & performance improvements.

One significant difference is with the Debug perspective layout. This has been improved to give more space to the editor, so it is easier to see your code. As with all perspective changes you are welcome to re-arrange it if it is not to your taste.









Per user data locations

Per user data locations


The latest version of e2 studio now supports per-user data areas rather than saving all files under the e2 studio installation directory.

This should not affect your operation of the tools. However, on occasion you may wish to browse the support files for a device for example.
It is possible to access this information from the Help->About e2 studio dialog, then click “Installation Details”.
If you then click “Support folders” it shows where your user data folders are located on your machine.
