This file summarizes user visible changes for each release.
Realase 2.6.1 2025/03/30
-------------------------
The Tcl "source" command is no longer redefined to support "-echo" and
"-verbose" arguments and redirecton. Use the "include" command instead.
include [-echo] [-verbose] filename [> filename] [>> filename]
-echo echos commands as they are read
-verbose prints command results as they are evaluated
Unlike the Tcl source command, "include" expands filenames with tilda '~'
and respects sta_continue_on_error.
Release 2.6.0 2024/07/22
