This address some minor bug fixes, and it reduces some of the writing we do to the terminal when changing attributes and using color.

Most of the rest of the commits in this release are related to improving test coverage, and enhancing the mock terminal backend. Note that the very useless SimScreen has been removed, as the MockBackend is far more functional.

Also some demos have moved from _demos to demos -- and they are now verified in the CI/CD. We will be doing this with the rest of the demos over time.

Full Changelog: https://github.com/gdamore/tcell/compare/v3.0.5...v3.0.6

This release is principally a bug fix release, but we also took this opportunity to remove the views sub-package.

This is technically a breaking change, but we don't think anyone has converted to v3 and is using the views package, and we meant to to do this as part of v3 originally.

The content that was in the views package might be introduced in another repository later, if desired. (If you were using the views package and miss it, please let us know! We'd be happy to resurrect it in another sub package.)

This fixes a regression where Control-J was being reported as KeyEnter.

Full Changelog: https://github.com/gdamore/tcell/compare/v2.13.4...v2.13.5

This release contains one important bug fix (for Control-J reporting on legacy terminals), and some refactoring intended to make feature detection and reporting better. There is a breaking change here in the TTY API, but we don't think anyone has adopted the v3 version of this yet, which is why we felt we could make this change.

• Fix various keyboard handling issues found in version 2 by @gdamore in https://github.com/gdamore/tcell/pull/904

(Note that v2.13.3 was accidentally tagged on the wrong branch -- it had the same content, but the git history was wrong -- we've deleted the tag.)

Note that folks relying on KeyBacktab will find that the regression where on some terminals it became KeyTab+ModShift is now fixed.

Full Changelog: https://github.com/gdamore/tcell/compare/v3.0.1...v3.0.2

One very unfortunate bug with key handling (capital letters not working) was found just after we released 3.0.0.

This release also adds some accessors which should have been in 3.0.0 but weren't. Technically this probably should have been a minor release, but we don't think anyone is likely to have started using 3.0.0 for real (particularly with the nasty bug we fixed), so we decided not to make it a minor release.

With this direct Attributes use is no longer recommended. Use the accessors on Style instead.

Version 3 is a major new release. It introduces improvements in the event handling, richer support for more keys and modifier reports, more functionality out of the box, desktop notification support, simpler APIs for emitting strings directly to the screen, and numerous bug fixes.

Every Tcell version 2 application will need some modifications to work with Tcell version 3. See the CHANGESv3.md document for more information.
