OpenTTD Portable 1.3.2 has been released. OpenTTD is an urban planning and simulation game in which the player aims to earn money through shipping of cargo by land, water, and air. It's packaged in PortableApps.com Format so it can easily integrate with the PortableApps.com Platform. And it's open source and completely free.

OpenTTD Portable is packaged in a PortableApps.com Installer so it will automatically detect an existing PortableApps.com installation when your drive is plugged in. It supports upgrades by installing right over an existing copy, preserving all settings. And it's in PortableApps.com Format, so it automatically works with the PortableApps.com Suite including the Menu and Backup Utility.

Features
OpenTTD is an open source simulation game based upon the popular Microprose game "Transport Tycoon Deluxe", written by Chris Sawyer. It attempts to mimic the original game as closely as possible while extending it with new features.

OpenTTD is licensed under the GNU General Public License version 2.0. For more information, see the file COPYING included with every release and source download of the game.

Significant enhancements from the original game include:
- bigger maps (up to 64 times in size)
- stable multiplayer mode for up to 255 players in 15 companies, or as spectators
- dedicated server mode and an in-game console for administration
- IPv6 and IPv4 support for all communication of the client and server
- in game downloading of AIs, NewGRFs, scenarios and heightmaps
- new pathfinding algorithms that makes vehicles go where you want them to
- autorail/-road build tool, improved terraforming
- canals, shiplifts, aqueducts
- larger, non-uniform stations and the ability to join them together
- mammoth and multi-headed trains
- different configurable models for acceleration of vehicles
- clone, autoreplace and autoupdate vehicles
- the possibility to build on slopes and coasts
- advanced/conditional orders, share and copy orders
- longer and higher bridges including several new designs, plus fully flexible tracks/roads under bridges
- reworked airport system with many more airports/heliports (e.g. international and metropolitan)
- presignals, semaphores, path based signalling
- support for TTDPatch NewGRF features offering many options for graphics and behaviour configuration/modification
- drive-through road stops for articulated road vehicles and trams
- multiple trees on one tile
- bribe the town authority
- many configuration settings to tune the game to your liking
- save games using zlib compression for smaller sizes, while not interrupting gameplay

- dynamically created town names in 18 languages, plus NewGRF support for additional languages
- freely distributable graphics, sounds and music
- framework for custom (user) written AIs
- zooming further out in the normal view and zooming out in the small map

Lots of effort has been put into making OpenTTD easy to use. These include:
- convert rail tool (to electrified rail, monorail, and maglev)
- drag&drop support for almost all tools (demolition, road/rail building/removing, stations, scenario editor, etc)
- sorting of most lists based on various criteria (vehicle, station, town, industries, etc.)
- mouse wheel support (scroll menus, zoom in/out)
- autoscroll when the mouse is near the edge of the screen/window
- sell whole train by dragging it to the dynamite trashcan
- cost estimation with the 'shift' key
- advanced options configuration window, change settings from within the game

Graphical/interface features:
- screenshots can be in BMP, PNG or PCX format (select in game options menu)
- more currencies (including Euro introduction in 2002)
- extra viewports to view more parts of the game world at the same time
- resolution and refresh rate selection for fullscreen mode
- colourful newspaper after a certain date
- colour coded vehicle profits
- game speed increase (through fast forward button or by pressing the TAB key)
- snappy and sticky windows that always stay on top and neatly align themselves to other windows
- more hotkeys for even less mouse-clicking
- support for 32 bit graphics
- support for right-to-left languages
- support for other (sized) fonts where the user interface scales based on the font and translation

Posting a full list would be futile as it would mean updating this page almost daily, and even then some things might be forgotten. Play with the game to experience all the features yourself, or take a look at the Wiki for a more thorough listing and explanation of the features and possibilities available.

OpenTTD 1.3.2 (2013-07-27)
In the middle of your vacation, just back from the OpenTTD and TT parties, so what to do next?
The answer is of course OpenTTD-1.3.2. During the OpenTTD party Belugas released the new stable version, filled with all fixes of the last Release Candidates.
- Fix: [Admin] End-of-rcon data could not be determined reliably for any rcon command [FS#5643] (r25598, r25588, r25587)
- Fix: [Content] When the server closed the connection, the client would for eternity try to read a packet and never timeout making it impossible to reconnect [FS#5635] (r25597)
- Fix: [Script] Changing the script difficulty level in-game would also change the settings using the default even though they were not allowed to change in-game [FS#5644] (r25592)
- Fix: [Admin] Ensure that sent and received length of json strings are the same [FS#5646] (r25590, r25589)
- Fix: [Squirrel] Stack overflow did not show an error, due to the stack to throw the error already being full [FS#5320] (r25585)
- Fix: [Script] Documentation implied that XXList::AddItem has a default for value if it isn't filled in [FS#5638] (r25579, r25577)
- Fix: Layouter caused significant slowdown with text heavy windows, cache it to make it managable (r25574, r25570, r25569, r25567, r25564)
- Fix: Make content list appear faster (r25573)
- Fix: Non-ICU layouter started new lines with the space which triggered the linebreak (r25568)
- Fix: If the next order cannot be resolved, reset the current order property instead of leaving it in an intermediate state [FS#5633] (r25562)
- Fix: [Squirrel] Infinite recursion loop in freeing data via a looping set of references [FS#5568] (r25558)
- Fix: One could build bridges over owned land of another company [FS#5524] (r25557)
- Fix: [Script] Texts from scripts were not validated before they were shown, causing an assertion to trigger [FS#5632] (r25555)
- Fix: Provide a warning when no vehicles are available, and tell what to do in that case [FS#5530] (r25553)
- Fix: Possible reading of uninitialised memory due to undefined execution order (r25551)
- Fix: [Windows] Race condition between two drawing threads could crash OpenTTD [FS#5571] (r25550)
- Fix: ICU returns the width of the visual run as if the trailing space was added (in case a newline was added). This caused the width to be more than the requested width, but it would still be drawn correctly [FS#5626] (r25547)
- Fix: Small memory leaks (r25546)
- Fix: [GS] The checks and validations for setting the extra text in the town window became too stringent [FS#5625] (r25544)
