ActiveTcl 8.6.6 Released

ActiveTcl 8.6.6

UPDATE Apr 13, 2017: ActiveTcl 8.6.6 is now available on macOS.
UPDATE Feb 7, 2017: ActiveTcl 8.6.6 is now available on Windows.


The Tcl Core Team has done an outstanding job with the 8.6 series, with 8.6.6 being the latest version. This version contains some enhancements, but the bulk of the release are bug fixes and improvements to items started earlier in the 8.6 lineage.

Today we are announcing general availability of ActiveTcl 8.6.6 on Linux, continuing the ActiveState tradition of providing binary distributions of the latest features in the Tcl language both to the community and enterprise customers. In this release we have greatly expanded the scope of the packages in the distribution by providing 21 popular Tcl packages (see below) by default on installation, and adding a large number of extensions to tclib that were previously only available via Teapot. Additionally, the ActiveTcl core now includes sqlite3 and the tdbc connectors for mysql, odbc, postgres and sqlite3.

The binary distributions for ActiveTcl on Windows and MacOS are ongoing and will be released shortly.

What's New in Tcl 8.6.6 (and ActiveTcl 8.6.6)

This new release of Tcl 8.6.6 includes the modifications from three Tcl Improvement Proposals (http://wiki.tcl.tk/983) which include:

There were also upgrades made to improve support for Unicode 9.0. The file command has improved support for Windows file conventions, and there were improvements made to Tk and Aqua appearance on MacOS.
