Some game definitions using the Remarkable Rookies army (which
uses a range-4 Rook) have been added as sub-variants of fairy.
+8/9/2014 Version 4.8T. Three bug fixes, some enhancements, two new variants:
+ * mark Rook non-virgin after castling, so it cannot gate in Seirawan
+ * Fix printing of variants feature in MaxQi
+ * Sending the setup command now also works with 3rd-rank Pawns
+ * Allow sending a parent variant with 'setup'
+ * Implement new method for indicating promo-zone width = 3
+ * Implement new variant nocastle
+ * Implement new variant ASEAN Chess
+ * Add option to play Makruk with Ai-Wok in stead of Met
+17/10/2014 Version 4.8U. Four new variants were added:
+ * Charge of the Light Brigade
+ * King of the Hill
+ * Bifurcator Chess
+ * Team-Mate Chess
+ General game-playing enhancements:
+ * Hoppers can now be specified as hopping over friendly pieces
+ only, and the point where the second move leg starts can be
+ moved to the step just before hitting the platform.
+ * Sliders will now toggle to their secondary move only once,
+ allowing bent riders at the expense of crooked ones.
+ * Code is added to recognize the situation 'bare King', and
+ give higher award for cornering it in that case, to make mating
+ with many weak pieces (as regularly occurs in Makruk) easier.
+ * When a mate of the bare King in one corner cannot be found,
+ points will be awarded to drive the King out of that corner to
+ another one, allowing it to successfully perform KBNK-like mates.
+ * Make it possible to mark pieces as invalid promotion choice
+ Embracement of new standards:
+ * Add logo, and install it according to new 'plugin standard'
+ * Install a (new) .eng file to comply with the plugin standard
+ * Issue the (new) XBoard 'piece' command for all non-standard pieces
+ New options:
+ * Fifty-move claiming can be adapted to the need of the variant
+ * A comment line can now be displayed with each variant through
+ an 'Info' button in the engine options
+ Bugfixes, two of fatal bugs:
+ * Fix printing of Seirawan gating moves
+ * Correct the moves of the Marshal in the Rookies army of CWDA
+ * suppress emission of a spurious (garbled) setup command at startup
+ * Fix positioning of Pawns in ASEAN Chess in setup command
+
+22/10/2014 Version 4.8V. Bugfix release for 4.8U:
+ * Fixes null move, which was broken by the bare King patch, as that
+ always set material (R) to 4, not just when bare King was detected.
+
+26/1/2016 Version 5.0a
+ A rather drastic enhancement of the general capabilities:
+ * Analyze mode is supported, meaning arrival of input is tested
+ during search. Both Linux and Windows code was added for this
+ * Move exclusion during analysis is supported (feature exclude=1)
+ * The number of board ranks is no longer fixed at 8, but can have
+ any value up to 16. This required the promotion 'upgrade' to come
+ from a table pt[], rather than being derived from rank number
+ through a hard-coded expression
+ * The promotion code now uses the true value of promotion pieces in
+ the search, rather than assuming Q and correcting it at game level
+ * Pawns can start on other ranks than the 2nd, and would normally
+ start at the edge of the promotion zone as indicated by the =N
+ suffix to the board size in the ini file
+ * A negative N in the =N suffix now does affect on which rank the
+ Pawns are placed, but leaved the promotion zone depth at 1 rank
+ * A spin-off of the table-driven promotion is that the promotion
+ piece can be made file-dependent. This is currently used to set
+ the choice to the piece that starts on that square, as a side
+ effect of starting the Pawns on 4th rank
+ * Initial triple pushes of Pawns can be e.p. captured on both
+ skipped squares on 10-rank boards, when they are specified as
+ first move on the white Pawn
+ * It is possible to define on Pawns a move that is both an
+ initial triple push as well as a double push when advanced only
+ one square. This uses the code that normally would be a 5-push
+ * Any pair of royals will now be subject to the procedure of
+ bare-King detection, and increase of its centralization weight,
+ rather than just piece 3 and 4. This makes it easier to order
+ the Kings last, for better LVA move sorting
+ * Stalemate can be configured as a win, currently triggered by
+ defining value -2 for the 9th piece (which then is a royal)
+ * The castling-through-check test now can test more than the
+ 3 squares starting at the King from-square, and really tests
+ upto the square next to the King destination. This would work
+ for castlings of any King stride >= 2
+ * The castling emptiness test now works for strides up to 4,
+ on boards of any width (was 3, and flaky for K-side 10-wide)
+ * Repetition detection now also is done inside the tree,
+ making it possible to plan for sacrificial perpetuals
+ * Bare-King checkmating is improved, by clearing the hash
+ table after every move (except mate scores and game history).
+ * The case with color-bound pieces is now handled by changing
+ the centralization table as soon as the bare King visits
+ a corner square into one that penalizes only the adjacent
+ two corners
+ * Against bare King all reductions are switched off, and a new
+ 2-ply extension is granted on a bare King leaving a corner.
+ This speeds up finding corner mates.
+ * A variant-specific file is used to pre-charge the hash table
+ with positions that are protected from overwrite. A file for
+ Makruk to help recognizing some difficult mates is included
+ in the install
+ * New engine-defined options 'Save in hash file' (button) and
+ 'Automatic persistent-hash dialog' (checkbox) can be used to
+ add positions to this persistent hash file.
+ * moves with bent trajectories can now be defined in the ini
+ file by adding the desired secondary step as third parameter
+ * clear hash on null-move switch, rather than spoiling the key
+
+ These enhancements have made it possible to add many new
+ variants, all out of reach before:
+ * Los-Alamos Chess (6x6 without Bishops)
+ * Janus Chess (10x8 with two Archbishops, stride-4 castling)
+ * Roman Chess (10x10, with two Commoners)
+ * Mexican Chess (10x10 with 2 Camels and Pawn triple-push)
+ * Ciccolini's Chess (10x10 with Adjutants (BDD) and Zebras)
+ * Grande Acedrex (12x12, game from 1283AD with bent sliders)
+ * almost-Wildebeest (11x10, with Gnu and 2 Camels)
+
+17/2/2016 Version 5.0b
+ Mostly bug-fixes, and some small interface improvements:
+ * Input of Makruk promotion moves (broken by 5.0a) fixed
+ * Fix false game repetitions from undo messing up game history
+ * Fix dropping out of analysis mode in checkmate position
+ * Improve game-phase definition to prevent King chasing
+ * Grand Acedrex piece values set to encourage Zebra promotion
+ * Randomization obeys 'random' command, suppressed in analysis
+ * Print mate scores according to new CECP standard
+ * pieceToChar strings adapted to new XBoard piece order

-and 10 (hex) = 16. So the piece zig-zags over the board, right, forward, right,
-forward, etc. Had the move attributes been 11032, captures would only
-be allowed on the odd steps (after moving right), while the even steps could
-only be non-captures (both the 1 and 2 bit are toggled). With 11030 the
-odd steps can only be skipped (if empty), and the even steps can both capture
-and non-capture, meaning the piece moves like a Bishop that can be blocked
-by a piece just next to the diagonal.
-
If the first step is a slider, a second step is made (if the square was
empty), but if the mode toggles to leaper, the move stops there (e.g. Horse).
