Abstract
This TIP serves to coordinate Tcl/Tk 8.6 development releases and the features they deliver.
Introduction
Following up on a message to the 'tcl-core@lists.sourceforge.net' mailing list, [http://aspn.activestate.com/ASPN/Mail/Message/tcl-core/3594952], a draft release calendar for Tcl/Tk 8.6 alpha and beta releases is presented below.
The intent is for developers working on Tcl and Tk to add under each release date those features they intend to make part of that release. For features which already are described by another TIP, a reference to that TIP is sufficient, and the recommended way to update this page. For features which have not yet been TIPped, a brief description and the names of those actively working on it are an acceptable temporary replacement, but should be replaced with a TIP reference as soon as one is ready.
This is meant to be a working document, which gets updated by all stakeholders to reflect ongoing progress and any changes of plan. It's not a contract or a promise, just a place to record the intents of an entire community of developers. Anything in it might be revised, and any intent expressed in it might well not be fulfilled. Due to its nature, there will never be any vote on this TIP. It is more analogous to similar informational TIPs like [31].

[392], Allow Bignums to be Disabled at Runtime on a Per-Interp Basis
