Het Tcl Core Team heeft een nieuwe en waarschijnlijk laatste onderhoudsversie in de 8.4.x-tak uitgebracht van het Tcl/tk-pakket dat bestaat uit de tcl-scriptingtaal en de bijbehorende toolkit. Tcl is een krachtige scriptingtaal die eenvoudig is opgebouwd en ondersteuning biedt voor verschillende platformen. Tk is een grafische toolkit voor deze scriptingtaal en geeft je de mogelijkheid om grafische applicaties te ontwikkelen. Het versienummer is inmiddels aangekomen bij 8.4.19 en het pakket wordt zoals gewoonlijk als broncode verspreid. De aankondiging van deze versie ziet er als volgt uit:
Tcl/Tk 8.4.19 Release Announcement
The Tcl Core Team is pleased to announce the 8.4.19 releases of the Tcl dynamic language and the Tk toolkit. This is the nineteenth patch release of Tcl/Tk 8.4. More details can be found below. We would like to express our gratitude to all those who submit bug reports and patches. This information is invaluable in enabling us to identify and eliminate problems in the core.
Routine maintenance of Tcl/Tk 8.4 has now come to an end. We intend Tcl/Tk 8.4.19 to be the final 8.4.* releases. The current stable releases of Tcl/Tk are 8.5.2, and development has begun on Tcl/Tk 8.6. It is possible that a bug fix of great enough importance or severity might prompt a release of 8.4.20, but there is no plan for that at the moment. Even that level of support will fade away quickly.
Summary of Changes since Tcl/Tk 8.4.18:
The following were the main changes in Tcl/Tk 8.4.19. A complete list can be found in the changes file at the root of the source tree. The more complete ChangeLog is also included with each source release. This is a patch release, so it primarily included bug fixes and corrections to erratic behavior. Below are only the most notable changes.Tcl Core Team and Maintainers
