For whatever reason I wrote 3.1.0-x up to now, it was v3.0.1-x actually.

New features:
<ul>
<li> 2D-view in OpenGL
- mouse wheel for zoom, left mb pressed to pitch, left mb plus ctrl key to move
- ctrl+ins (resp. 0 at number pad) resets view
<li> UI configuration
- completely new
<li> UI new game
- revamped (preliminary, I don't like this solution)
<li> Configuration is saved in XML format
</ul>
Unfortunately there are still a lot of bugs in the code. For instance you may experience flickers at 2D view on Windows. You can try one of this versions:
Windows, 32bit
Linux, Gtk2, 32bit
Linux, Qt, 64bit

* bugs in AI fixed
* optional auto pause on local games (useful to hide bank for mates)
* letter set can be assigned to dictionary (useful for exotic dictionaries like english_phonetic that do not have preset fix implemented)
* variable bonus for scrabbles

* improved visualization: antialiasing works with Windows (no "steps" in case of lines), pieces have an (optional) reflection, bonus fields are (optional) transparent, forced redraw after each move
* improve presentation of options
* a couple of minor bugs fixed

* Complete repaint before computer calculation
* Graphics considerably faster

It would be interesting if someone still experiences low framerate. The fps value is shown in the header of the 2d view.

* Designs are fully implemented now (samples Earthgems and Afghan made by @Apollonius are available, however without different model data i.e. board appearence)
* some bugs fixed, some improvements on performance

* Bugs in calculation of moves fixed (the number of found words was not equal for running game and post-hoc analysis, probably leading to some other errors)
* Bugs in 3d visualization fixed (2d design and letters in 3d broke when on changed settings)
* Bug during dragging of letters fixes
* CPU consumption reduced (views are not painted on idle anymore but on demand)

* Own display settings for translation and rotation are not destroyed anymore when the options dialog is opened
* The first node is now selected by default in configuration tree
* Bugs in calculation of moves fixed (the number of computed words was not equal between running game and post-hoc analysis, probably leading to some other errors)
* Bugs in 3d visualization fixed (broken 2d design and 3d letters on change of settings)
* Minor changes in main menu (word search is located at file now)
* Fast access to word search added to toolbar
* Original hints revised
* Selection of past move (game history) is now possible during network games as well (not only at game end)
* Default distance of scrabble cube is adjusted according board size
* Running games are loaded automatically after invitions (no explicit refresh necessary anymore)
* Rack adjusts its height according tiles (wrapping does not lead to hidden tiles anymore)
* Chat input is focused on enter only now
* Improved placement of main form panels (bug with wrong cursor symbol removed, easy resizing with splitters, but only 3d view can be used as separate form)
* Donation option via Gittip added (https://www.gittip.com/Scrabble3D/)
* In network mode, the dialog on new game is auto closed with cancel result after 30s (as for polls)

* Color for chat messages is not misapplied to any information on Linux
* Crash on program end fixed
* Flicker at 2d board under Windows on mouse actions fixed
* Issue about confirmation on next move for time per move fixed
* Anagram feature added to word search
* File default.lang is not shown in selection anymore (empty translation strings are still not applied)

* minor compilation change that prevented app from running with >XP

* Old newgame dialog resurrected
* Exception safe formatting arguments (%s vs. %d)
* Computer 'trusts' placed words in challenge mode with an adjustable percentage
* Final calculation will be shown always after loading the stored game; including zero points for joker
* What-If-Only variant (letters on rack can be jokerized by ctrl+right click; but move has to score with at least 50 points)

Its better to stay in the 3.1 line. So this release will be 3.1.1 (and not 3.0.2).

* Bug fixes
* Internal processing of network messages changed

* some minor fixes
