Welcome to Freeciv 2.3
======================

The most important changes between major releases are shown below.
Not all changes are shown here. To see detailed changes in the 2.3
series, check NEWS-2.3. Those who are interested in seeing more
detailed changes should check the ChangeLog file.


MAJOR CHANGES FROM 2.2.x to 2.3.0
---------------------------------

   (from <http://www.freeciv.org/wiki/NEWS-2.3.0>)

   As well as many new features, many features from Longturn and some from
   Warclient have been merged into the main codebase for this release.

   A new program has been added to the Freeciv suite: 'freeciv-modpack'.
   This makes it easier to download and install add-ons ('modpacks':
   rulesets, tilesets, etc) to the right place; you can enter a URL,
   choose an add-on from the list, and the tool will install it to the
   correct place for this version of Freeciv to use it. Modpack authors
   should see this page for details of how to publish modpacks for
   installation by this program. GNAPATCH#1822

   As is usual for major releases, 2.3 clients cannot interoperate with
   pre-2.3 servers, and vice versa. Pre-2.3 savegames can however be
   loaded into 2.3, and in most cases, the supplied rulesets have not
   changed so much as to make it difficult to complete a game started with
   2.2.x's rules.

Server / General

Gameplay

     * Various limits have been lifted, including:
          + Maximum number of simultaneous players increased from 30 to
            126 GNAPATCH#1731
          + Map size
               o Maximum map size increased from 30,000 to 128,000 tiles;
                 maximum linear map dimensions increased from 254 to 512
                 GNAPATCH#1733
               o Minimum map size reduced to 16x16(!) GNA#17031
          + Allow goto paths that take more than 99 turns GNA#16792
     * There are now more ways of specifying the map size. Instead of
       specifying the size in thousands of tiles (via the 'size' option),
       you can specify the number of tiles per player ('tilesperplayer'),
       or the exact X and Y sizes ('xsize' and 'ysize'). The method is
       selected with the 'mapsize' option. GNAPATCH#1720
     * A number of new server settings have been added to customise
       gameplay:
          + 'killunhomed': units without a home city (such as starting
            units) can be configured to lose hitpoints each turn until
            they die. GNAPATCH#1501
          + 'unreachableprotects' controls whether 'unreachable' units
            (such as Bombers) protect the whole stack on their tile as in
            previous versions. If this is unset, a mixed stack is
            vulnerable to attack (including normally-unreachable units).
            GNAPATCH#1850
          + 'unitwaittime' allows a minimum time to be enforced between
            actions of a given unit on successive turns, to mitigate the
            'double-move problem'. GNAPATCH#1500
          + 'restrictinfra' allows enemy use of infrastructure such as
            roads and rails to be restricted. GNAPATCH#1266
          + 'airliftingstyle' allows airlifts between allied cities, and
            unlimited airlifts per turn. GNAPATCH#1189
          + 'techlost_recv'/'techlost_donor' allow introduction of a risk
            of technology loss when technologies are transferred between
            civilizations (via diplomacy, espionage, conquest etc).
            GNAPATCH#1263
          + 'trading_tech'/'trading_gold'/'trading_city' allow certain
            types of diplomatic agreements to be selectively disabled.
            GNAPATCH#1504, GNAPATCH#1506
          + 'globalwarming'/'nuclearwinter' allow these global
            catastrophes to be disabled. GNAPATCH#1505
          + 'team_pooled_research' allows pooled research to be disabled.
            GNAPATCH#1868
          + 'alliedvictory': all players in an alliance can share victory.
            This new behaviour is enabled by default. GNA#14278
     * (as of rc1) Changes to the 'timeout' setting now always have
       immediate effect, as in 2.0.x; previously, changes between non-zero
       values would not take effect until the next turn. GNA#18079
     * Improvements to observing:
          + The demographic report is now available to global observers.
            GNA#16486
          + Global observers can now view the city report (it shows cities
            from all nations). GNA#16699 GNAPATCH#2571
          + Global observers can now access the buildable target list in
            the city dialog. GNA#16487
     * The number of units built, killed, etc now contributes to the final
       score, and appears in the endgame report. GNAPATCH#1870
     * Changing a unit's activity is now more forgiving: if you
       accidentally stop an activity such as irrigation, but restart it
       without doing anything else, progress is no longer lost. GNA#15510

Clerical

     * Settings configuration on the client and server has been reworked.
       The most notable change is that enumerated and bitwise options are
       now set with strings instead of numbers (for instance, '/set
       barbarians hordes' instead of 4, '/set topology wrapx|wrapy'
       instead of 3). GNAPATCH#1301
     * The FREECIV_PATH environment variable can be overridden by three
       new variables: FREECIV_DATA_PATH, FREECIV_SAVE_PATH, and
       FREECIV_SCENARIO_PATH. GNA#14624
     * Add-ons are now loaded from a sub-path ~/.freeciv/<version>/ (e.g.,
       ~/.freeciv/2.3/), since they tend to be specific to a version of
       Freeciv. GNA#14624
     * Servers send more information to the metaserver:
          + The 'timeout' and 'aifill' options (GNAPATCH#2092);
          + (as of beta2) the number of human players (as opposed to AIs)
            (GNAPATCH#2312); as of beta3 this is displayed in the client
            (GNAPATCH#2411)
     * New server command '/kick' and associated option 'kicktime' to lock
       out troublesome users. GNA#16933
     * New server commands '/ignore', '/unignore', and '/list ignored
       users', allowing players to suppress chat messages from specific
       users. GNAPATCH#1910
     * The '/create' command can now create a new player even in a running
       game. GNAPATCH#1574
     * New command '/lua' to execute a line of Lua script on the server
       command line. GNA#15644
     * More options have been added to the '/reset' command. GNAPATCH#1284
     * The name of the scorelog file is configurable with the new
       'scorefile' option. GNAPATCH#1750
     * The current ruleset can be shown by '/show rulesetdir' instead of
       '/rulesetdir' (this allows less privileged users to do so).
       GNA#16636
     * Observers can see the current votes in progress with the new
       command '/list votes'. GNA#16635
     * The server uses a new format for savegames. It can load savegames
       generated by old versions of Freeciv, but old versions will not be
       able to load new savegames. GNAPATCH#1541
          + Support has been added for future versions of Freeciv to save
            backward-compatible savegames (back to 2.3.0) via the
            'saveversion' server option.

Clients

     * Various report screens have been reworked so as not to redraw and
       lose their selections after a few seconds. GNA#16439
     * The total revenue from trade routes is now visible in the city
       report. GNA#16812
     * The chat log file name is now configurable. GNAPATCH#1749
     * (GTK) Some rework of the pregame connection screen and menus
       (GNA#16685). Buttons on this screen now adapt to selected
       player/user (GNA#15300).
     * (GTK) Tab completion of user and player names on the chatline.
       GNAPATCH#1867
     * (GTK) The goto/airlift dialog now shows which nation each city
       belongs to, and more detail on airlift capacity. GNA#15313
       GNAPATCH#2588
     * The research report is now updated when tax rates or city science
       output change. GNA#16776
     * (as of beta2) Improve handling of (non-default) rulesets which
       restrict reachability of technologies (via root_req in the ruleset)
       in the science report. You can now choose whether unreachable
       technologies are displayed. GNA#16852, GNA#16855, etc
     * (as of beta2) (Xaw) The Take Player command is implemented.
       GNAPATCH#2253
     * (as of rc1) In 2.2.x, the "Sell Obsolete" button in the Economy
       report could never be pressed. It has been renamed to "Sell
       Redundant", and now lets 'redundant' buildings be sold en masse
       (redundant buildings are those whose effects are entirely
       superseded by another, for which you may still be paying upkeep --
       for instance, Power Plants are redundant in cities with a
       Hydro/Nuclear/Solar Plants). In the Gtk client, the "Obsolete"
       column in the Economy report has been replaced with a "Redundant"
       column showing how many of each building in your empire are
       redundant. GNA#17937

Gameplay / Rules

Changes affecting supplied rulesets

     * Two new rulesets are included in the distribution:
          + multiplayer: a ruleset based on the default but tuned for
            multiplayer games, based on Madeline Book's "rewonder" ruleset
            for 2.1.
          + experimental: a ruleset showcasing new features of the Freeciv
            "engine", without strict regard for game balance and
            playability. It enables some of the new features mentioned
            below, such as variable city radii.
     * More than doubled the number of playable nations (from 187 to 387).
       Many improvements to existing nations, such as using native
       spellings for cities and leaders.
     * The interaction of promotions and diplomat-vs-diplomat contests has
       changed:
          + Attacking diplomats can now gain experience; previously, only
            defending diplomats gained experience. GNA#17265
          + The effect of veterancy on the outcome of these contests has
            been reduced; it can change the odds by at most 20%
            (previously, elite diplomats could become practically
            invincible). GNA#17264
     * The terrain effects of global warming and nuclear winter are now
       more severe: land can be lost to ocean (and vice versa), and
       glaciers can melt. GNA#17105
     * If migration occurs, citizens take half the food in the granary
       with them. GNAPATCH#1232
     * (as of rc1) In rulesets with Fundamentalism, it now has a happiness
       penalty for empire size (as it did in 2.0.x). GNA#18133
     * (as of rc2) The civ2 ruleset now uses a restricted set of 25
       nations, to better resemble the original game. Loading civ2
       savegames from older versions of Freeciv may cause nations to be
       reassigned; it will not be possible to load a civ2 savegame with
       more than 23 (non-barbarian) players. GNA#18419

New features for ruleset/modpack/scenario authors

   These features have been added to the Freeciv "engine", but aren't
   enabled in standard rulesets (except the experimental ruleset, in some
   cases).
     * Variable city radius: the circle of tiles able to be worked by a
       city is no longer fixed but can vary (radii from 1 to 5 possible)
       depending on requirements defined by the ruleset. GNAPATCH#1235
          + Accordingly, the maximum value for the 'citymindist' server
            option has been increased from 5 to 9. GNAPATCH#2262
     * Build slots: in ruleset-defined circumstances, cities with large
       production surpluses can now produce more than one of a given type
       of unit per turn. GNAPATCH#1234
     * Tech upkeep: rulesets can cause some research output to be diverted
       to maintaining expertise in existing technology rather than
       discovering new technology, with the risk of losing advances if the
       upkeep is not met (similar to gold upkeep for city improvements).
       GNAPATCH#1264
     * Rulesets can define units that can be converted into another type
       of unit on the player's command. GNA#13890
     * Rulesets can define "Capturable" units that can be captured by
       certain other "Capturer" units. (There is an associated server
       option 'homecaughtunits'.) GNAPATCH#1851
     * Rulesets can suggest or mandate server settings. GNA#13873,
       GNAPATCH#1200
     * A start position in a scenario can now be restricted to a set of
       nations rather than a single nation. The built-in editor now
       supports editing this set. GNA#13803
     * Various improvements to Lua scripting. See Events Reference Manual
       for some more detail.

Tilesets / Art

     * New default tileset with redrawn terrain graphics: "Amplio 2". The
       original Amplio tileset is available for 2.3 as an add-on (it can
       be found with the freeciv-modpack utility). GNAPATCH#1777
     * Larger versions of flags and shields are now included in the
       Freeciv distribution for use by larger tilesets; they are used in
       Amplio2 (as of beta4). GNAPATCH#2202

Translations

     * (as of rc2) New Scottish Gaelic localization (complete).
     * (as of beta3) New Irish Gaelic localization (not yet complete:
       55%).
     * Updated translations:
          + Complete translations: Polish, French, Spanish, Catalan, and
            British English.
          + Incomplete translations: Danish (95.8%), Finnish (85%),
            Ukrainian (81%), Italian (74%), Japanese (70%), Brazilian
            Portuguese (70%), Russian (69%), Swedish (60%), Lithuanian
            (43%), and Simplified Chinese (40%).

KNOWN ISSUES

     * There are some regressions in the SDL client relative to 2.2.x:
          + The city dialog has not been redesigned to accommodate the
            larger city map required by variable city radius support. As a
            result, the city map display is scaled down and difficult to
            read. GNA#15804
          + Not all setting types can now be modified; bitwise and color
            settings are not yet supported. GNAPATCH#1631 GNAPATCH#1957

                 a certain size is generated as Lake)
          + Triremes are not restricted to tiles next to land, but to
            (shallow) Ocean tiles; they now cannot even attempt to enter
            unsafe tiles
          + Triremes no longer get the +1 movement bonus from Nuclear
            Power that other sea units get
          + Triremes and Carriers can no longer attack land units
          + Submarine attack strength reduced from 15 to 12 (to make it

          + New advance Environmentalism and Solar Plant improvement,
            which can eliminate pollution from production
          + Trade route value now depends on size of cities, not on trade
            generated in them
          + New national borders system

            instead of 100%
          + New nations

     * AI difficulty level: Cheating
     * New server options:

          + foggedborders: visibility of borders is subject to fog of war
          + borders gains new modes where player can see all tiles inside

               o City Report: F1 to F4
               o Go/Airlift to City: Shift+L to T
               o Wake up Others (Shift+W) becomes Unsentry all on tile
                 (Shift+S)
               o Orders menu split into Select, Unit, Work, and Combat;

   at 50% before being divided).
 - Glacier terrain is now unsafe for land units (15% chance per turn of
   being lost). Also doesn't count as coastline for Trireme safety or Fish
   and Whale generation. Roads/railroads can be built but all units (worker
   too) get 15% chance per turn of being lost any way!

   maps.
 - You can load savegames from the server prompt.
 - You can save client commandline defaults.
 - Specialists are taken from content citizens first, instead of from

   correspond with what they mean.
 - Improved players dialog shows sortable and colored information,
   including the players' flags.
 - Server no longer takes the --server command line option,
   instead you can use the --info option to set the metaserver
   announcement text to whatever you like. The -a option when given
   to the client skips the connection dialog entirely.

 - A new flexible timeout set through "timeoutinc" server option.
 - Leftover research bulbs will carry over to next advance.

 - Server option "tinyisles" allow 1x1 size islands and 
   "separatepoles" allow continents connected to the poles
 - "citymindist" specify minimum distance between cities, while 
   "notradesize" and "fulltradesize" regulate the trade generated 
   by smaller cities.
 - You can turn on angry citizens with "angrycitizens" option.

   isometric tiles are still available by giving a --tiles argument to
   the client, fx "civclient --tiles trident".
 - While planning a goto (after hitting "g") a line will be displayed
   showing the route from the selected unit to the mouse pointer.
   Hitting "g" will insert a waypoint at the mouse pointer.

   fx "cu<TAB>" completes to "cut", and if there exist a player named
   "paulz" "cut pau<TAB>" will complete to "cut paulz".
 - Players can agree to give shared vision, which means that you
   automatically see everything the other player sees.

 - Settlers can only be added to cities less than size 8, as in civ 2.
 - If you paradrop a unit into unknown terrain and the terrain contains
   an enemy unit the paradropping unit is lost. If you drop into terrain
   you thought was land, but which has changed to water, the unit is
   also lost.
 - diplomats/spies can't take action from a ship.
 - Refueling air units at turn update will refuel units with only 1 fuel
   first. Secundary criteria is unit cost.
 - Trireme loss percentage depends upon known technologies.
 - Leonardo's workshop will upgrade a random unit each turn, and not
   just the next one.
 - Allied cities count as friendly when determining whether a unit is
   being agressive. (gives unhappyness under some govs.)
 - Deserts are created primarily 15 to 35 degrees off the equator.
 - Only arctic tiles generated at poles.
 - The server will report when a new government becomes available.

 - Now requires a minimum number of ocean tiles to be adjacent to a land
   tile wished to be transformed into ocean.  Default is 1.
 - Added Nuclear Fallout.  Industrialization and population still
   generate Pollution.  Dropping a Nuke generates Nuclear Fallout, which
   is distinct from Pollution.  There is a new command to clean Fallout
   vs. cleaning Pollution.  Fallout contributes to Nuclear Winter --
   which also changes terrain, but tends to Desert, Tundra and Glacier.
   Added a new "cooling" icon to the info area to indicate the progress
   towards Nuclear Winter, and also an icon for Fallout on the main map.
   AIs are now more aggressive at cleaning up Pollution, but not Fallout.

 - Lots of bug fixes, code cleanups, and help-text improvements.

WHAT'S CHANGED SINCE 1.8.1:

 - Internationalization added.  Some aspects still need improvement,
   and in particular currently only works well if client and server
   both use the same language.  Initial (partial) translations
   included are: de es fr hu pl pt pt_BR.
 - Improvements to "trident" tileset, and this set is now the default.
 - New ruleset support for NATIONS, and many new nations added --
   there are now 32 nations in the default nations file.  Also allow
   multiple leaders choices for each nation, allow longer player

 - From Civ2, added Paratroopers unit and Airbase infrastructure.
 - Initial window size of Gtk+ client is smaller, to fit better on
   smaller screens, and can now resize detached chat/output window.
 - City report enhancements: New "Change All" dialog to convert all
   production of a given item to some other item (both clients); can
   select multiple cities and issue commands (Gtk+ client only); can
   sort by different columns (Gtk+ client only).  Can also select
   multiple items in the Trade Report (Gtk+ client only).
 - In Civ2 style, can select which infrastructure item to pillage, and
   multiple units can pillage together.  Can now pillage fortresses,
   as well as new farmland and airbase infrastructure items.
 - More fields added to Demographics Report, and now configurable from
   a server option.
 - Added more information to "Active Units Report", and renamed to
   "Military Report".
 - New cursors added for Goto, Nuke and Paradrop modes; <Escape> key
   cancels Go-To/Paradrop/nuke mode; pollution on city squares is now
   always clearly visible; improvements to refresh method for pixmaps
   in Gtk+ client; various other improvements to both clients.
 - Autosettlers no longer convert Plains/Grasslands to Forests, but
   will now Transform terrain.
 - AI can build spaceships, although does not do so very aggressively
   or intelligently yet.
 - Server and client may specify a different metaserver to use.  There
   is now a metaserver running on www.freeciv.org, and that is now the

   modpacks to give modified help to correspond to modified items.
 - Format of ruleset files is changed, no longer compatible with
   those for 1.8.0 and 1.8.1.
 - Removed science bonus of +1 per city per turn.
 - In Civ2 mode, overflight of a hut causes it to disappear, and can't
   build cities next to each other.
 - Rapture_size now 3, to conform to Civ2.
 - Settlers and Engineers now cost shield upkeep as well as food
   upkeep (depending on government type) as in both Civ1 and Civ2.
 - Helicopters do not lose hitpoints when over an airbase.
 - The amount of food required for a city grow is now ((citysize+1) *
   foodbox), instead of (citysize * foodbox); new behavior matches
   both Civ1 and Civ2.
 - Some re-organization of data directory, in adding data/scenario,
   and graphics now in data/trident, data/engels and data/misc.
 - Preliminary support for compiling the server on Mac (but networking
   code not yet ported).

 - Lots of bug fixes, code cleanups, and help-text improvements.

WHAT'S CHANGED SINCE 1.8.0:

 - The biggest change is a new client which uses the popular Gtk+
   toolkit.  The old Xaw client is still included as well.
 - A new alternate (30x30) tileset: the "trident" tileset.
   Start the client with "--tiles trident" to try it out.
   (This replaces the "classic/brunus" tileset, which is still
   available separately from the Freeciv ftp site.)
 - In the Gtk+ client, parts of the main window can be detached.
   Detaching them all allows a full-screen map window!
 - The data directory can now be specified as a "path" ($FREECIV_PATH),
   instead of a single directory.  By default, ~/.freeciv is now in
   the path, so if you download new tiles, modpacks, etc, you can now
   simply put them in ~/.freeciv
 - Server console improvements: can abbreviate server command names,
   and server option names.  Better prompt handling - eg, server no
   longer prints an unnecessary prompt each turn.

 - As always: lots of bug fixes, code cleanups, and help-text
   improvements.

WHAT'S CHANGED SINCE 1.7.2:

 - Space race!  Be the first player to build a space ship and colonize
   Alpha Centauri.
 - Civil war!  Capturing the enemy capital may split his empire.  Half
   of his towns will join a new AI leader!
 - Two tile sets in this release! The "big" ones are from Ralph Engels.
   I hope you will enjoy them.  The second set is an enhancement of the
   classic ones.  The server option -tiles allows to choose a subdirectory
   of the data directory to use different tiles.  (The data directory can
   be set with the DATADIR environment variable.)  Also, diagonal roads
   and railroads are now drawn.  Changed some of the national flags
   (especially changed Soviet flag to the Russian flag for Russians).
 - Rulesets can be used to customise units, advances, wonders, and
   improvements without recompiling -- see README.rulesets.
 - Units in a town can be put in auto-attack mode.  In this mode, they
   will attack any enemy units which come nearby.
 - New city options for each city, controlling whether new citizens are
   workers or specialists, whether to allow disbanding a size 1 city by
   building a settler, and options for units on auto-attack mode in the
   city.
 - Mapgen 4 (selected with the server command "set generator 4") is a new
   map generator which generates a map with 2 players on each island.
 - Cities can be a traded in diplomatic treaties.  This effectively
   allows you to exchange, sell or buy cities.
 - The AI now builds diplomats to defend against enemy diplomats.
 - Settlers and engineers can do teamwork.  With enough manpower, all
   terrain improvements can be done fast!
 - With engineers, the terrain type can be changed using the new Transform
   command ('O').  For example, hills can be turned into plains.
 - Units only regenerate hit points if they have not moved at all for a
   full turn.
 - Gamelog option.  The whole history of a game can be stored in the
   gamelog file.
 - One can select a unit with 0 moves left from the main map.
 - City workers can be adjusted from the main map, with shift+button1.
 - Changed the order of libraries to fix problems on IRIX and Cygwin.
 - Changed the client-server protocol to use network byte order.

 - Clearer Yes/No toggle buttons in various places in the client.
 - Reduced color usage (but looks almost identical), so the client should
   now work fine on systems with 8 bit color displays.
 - Ability to use "scenarios", that is, pre-designed maps.  Scenarios
   for Earth and Europe games are included in the data directory.
   (Use them with the server command-line option -f, like savegames.)
 - More city names, so you're less likely to see "City 41" etc.
 - Saving large games is now much faster, and the savefile is smaller.
 - Improvements to the documentation and online help system, including
   a new help section on the "Zones of Control" game concept.
 - Detect repeated log messages and print repeat counts.
 - New server options randseed and aqueductloss.
 - Many other enhancements and bug fixes.

   Also, they can modified by clicking on the rate status icons.
 - The behaviour of spies and diplomats has been greatly improved.
 - Freeciv now needs to transmit a lot less data (<25%!) when playing
   over the Internet.  This will greatly speed up games.

 - From now on, it will be possible for different Freeciv versions to
   talk to each other if they're able.

   getting over 6,000 hits per month.  He was quoted as saying "Cool!
   Now my computer is doing something!"
 - Lots, and Lots, and Lots of donated patches. Thanks guys, keep 'em
   coming!
