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.
