In gui.run, allow any existing interaction to terminate first. - -- Change 'The program' to 'Your program' in an IDLE 'kill program?' message - to make it clearer that the program referred to is the currently running - user program, not IDLE itself. - -- Issue #24750: Improve the appearance of the IDLE editor window status bar. - Patch by Mark Roseman. - -- Issue #25313: Change the handling of new built-in text color themes to better - address the compatibility problem introduced by the addition of IDLE Dark. - Consistently use the revised idleConf.CurrentTheme everywhere in idlelib. - -- Issue #24782: Extension configuration is now a tab in the IDLE Preferences - dialog rather than a separate dialog.

The custom theme will work with any IDLE - release, and can be modified. - -- Issue #25224: README.txt is now an idlelib index for IDLE developers and - curious users.
