Highlights of Tcl 8.5: * Speed: 8.5 now runs 10% faster than 8.4 with bytecode improvements, object caching and reduced memory usage. * Bignums: Tcl now supports arbitrary-precision integers, which improves math operations on large integers. * Safer interps: Tcl's powerful safe interpreter mechanism now has improved control of time and command limits in slave interpreters. * clock command: More robust implementation of command for specifying time, with significant l10n and i18n improvements. * dict command: New data structure that allows access to data by value rather than a variable name, which is substantially faster. * Additional improvements: Faster list search, new and improved mathematics procedures, anonymous procedures, new ways to package Tcl extensions, Tcl-level custom channel types, file and line location information for each command, and more.
Highlights of Tk 8.5: * New modern theming engine: New and additional widgets that make use of platform-specific theming on Mac OS X and Windows to better fit in with those environments, and feature an improved look and feel under X11. (For screenshots, see http://wiki.tcl.tk/13636.) * Font rendering: Now uses anti-aliased text under X11, and a more modern text engine (ATSUI) on Mac OS X. * Text widget: Smooth scrolling, widget peering, and improved procedures for counting and replacing text. * Additional improvements: Window transparency, new fullscreen option for windows, enhancements to specific widgets and window layout, and more.

2. Does developing with this environment require one to do hacking in C++? (I'm not interested in hacking with C++.)
3. Can anyone point me to applications that already exist that make use of Mozilla as a development deployment platform? I'm already familiar with Firefox, Thunderbird, and Komodo. Are there any others? (i.e. that are standalone apps and don't run as Firefox extensions, say?)
4. What kinds of applications are *not* feasible with this development platform?
