Tcl/Tk 8.6 Release Calendar

Following up on a message to the 'tcl-core@lists.sourceforge.net' mailing list, [], 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 .

, Tcl Channel Transformation Reflection API, Object Orientation for Tcl, Script Cancellation with interp cancel and Tcl_CancelEval, Extend binary Ensemble with Binary Encodings , A Standalone chan pipe Primitive for Advanced Child IPCNRE core. This is an internal change that allows infinite recursion and enables new features (like ::tcl::unsupported::tailcall). Official API exposure was in later versions. , A Unique Prefix Handling Command, Absolute Positioning of Canvas Items, A Convenient C-side Command Option Parser for Tcl, Tcl Database Connectivity (TDBC), Inexact Searching in Sorted List, Ensembles with Parameters, Add pathSeparator to tcl_platform Array, Portable Access Functions for Stat Buffers, Extend Default Whitespace in string trim Beyond ASCII, Improved Variable Handling in the Core Object System, Add a tk busy Command, Do Nothing Gracefully, Add -stride Option to lsort, Proper Tailcalls, Coroutines, Eliminate interp->result from the Public Headers, Allow lset to Extend Lists , Moving Vertices of Canvas Items, Angled Text on a Canvas, Unfocussed Text Widget Cursor Control, Add tempfile Subcommand to file, Add Support For Zlib Compression, Make TclTransferResult() Public, Add a tk busy Command, Publish the NRE API, A Standard Dialog For Font Selection, Try/Catch/Finally syntax, Half-Close for Bidirectional Channels, An API for Detecting Active Interpreters, Supported Access To interp->errorline, Make TclBackgroundException() Public, Embedder Access to Startup Scripts of *_Main(), Multiple dict filter Patterns, A Binary Specifier for format/scan , Bundle [incr Tcl] with the Core Tcl distributionNote that this is Itcl-ng (Itcl 4.0), and it is done by the external packages mechanism., Change Default <MouseWheel> Bindings Behavior, PNG Photo Image Support for Tk, Substituted 'errorstack' / 'traceback', NR-enabled Expressions for Extensions, Minor Production-Driven TclOO Revisions, NR-enabled Substitutions for Extensions, Export TclLoadFileEnables bundling of TDBC drivers with Tcl., Extended Window Manager Hint SupportNote that this is also being backported to 8.5 and 8.4; it is in response to a change in expectations in third-party software., Modernize X11 Menus, Simple 32 and 64 bit Registry Support These have been voted in, but not yet implemented. , Threading Support: Configuration and Package These are currently on the schedule to make 8.6, though in some cases only partially. , IPv6 Sockets for Tcl, Windows-Style Open and Save File Dialog on UnixMight only be partial (e.g., the parts that do not require an API change). Depends on how fast we can stabilize Tcl and Tk and fix issues. The more community testing we get (and help with coding too), the better. Note that 8.6b2 is effectively an early Release Candidate for 8.6.0. If too much changes (other than direct bugfixes) after 8.6b2, we will need an 8.6b3, which will add months of delay for the final release... The major constraint is simply developer effort.
