[TCLCORE] Tk 9.0.3 RELEASED

[Jan N. <jan...@gm...>]

Tk 9.0.3 Release Announcement
==============================

Nov 13, 2025

The Tcl Core Team is pleased to announce the release of Tk 9.0.3.
This is the third patch release of Tk 9.0.

The Tk Toolkit is an extension to Tcl, providing commands and support
for the creation of graphical user interfaces.  Tk originates with John
Ousterhout and his team at U.C. Berkeley in the late 1980s.  Its development
is continued by the efforts of a global network of volunteers guided by
the Tcl Core Team.

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. Such reports can be submitted here.

Where to get the new releases
=============================

Tk 9.0.3 sources are freely available as open source from the Tcl
SourceForge project's file distribution area:

 > [Tcl Source Distribution](https://sourceforge.net/projects/tcl/files/)

The Tk 9.0.3 distribution is source code only.  We keep links to some
third parties offering pre-built binaries for various systems here:

 > [Tcl Binary Distribution](https://www.tcl-lang.org/software/tcltk/bindist.html)

Tcl Improvement Proposals (TIPs)
================================

Each new user-visible feature in Tk should find its origins in a Tcl
Improvement Proposal (TIP).  TIPs are published, edited, considered and
voted in public, and should contain valuable information about how a
feature came to be the way it is.  See the full collection here:

Tk 9.0.3 Changes Summary
========================

(from changes.md in the source code distribution)

The source code for Tk is managed by fossil.  Tk developers coordinate all
changes to the Tk source code at

 > [Tk Source Code](https://core.tcl-lang.org/tk/)

Release Tk 9.0.3 arises from the check-in with tag `core-9-0-3`.

Tk 9.0.3 continues the Tk 9.0 series of releases.  The Tk 9.0 series
does not support Tcl 8.6.  The Tk 9.0 series extends the Tcl 9.0 series.
To make use of Tk 9.0.3, first a Tcl 9.0 release must be present.
As new Tk features are developed, expect them to appear in Tk 9, but not
necessarily in Tk 8.

Tk patch releases have the primary purpose of delivering bug fixes
to the userbase.
