    scrolling functions.

  - Savehandler: Avoid reading config more than once per game

  - Corrupt zip files now appear as "incompatible" on game loading/saving

  - Fixed bug #1724073: AI crashes when some AI slots are empty

### Gameplay

  - New Frisian tribe

  - New "Village" starting condition

  - New "Barracks" (casern) building for recruiting soldiers. Soldiers are no

    longer created by warehouses. Production sites can now have workers as input

    to consume.

    when depleted

  - Balancing: Improvements to various production sites' logic

  - The worker program "plant" no longer takes "tribe:" as a parameter;

    immovables are now identified via their attributes only, and both world and

    tribe immovables are searched. As a side effect, tribe immovables can now

    have terrain affinity.

  - Forester/Ranger now prefers good soil, and is thus more efficient

  - Make the scout aware of nearby military sites. The scout now switches

    between random walking and doing an excursion to enemy military sites

  - When a Fish Breeder's fishing grounds are full, display a special tooltip

    instead of sending an "Out of Resources" message

  - When a warehouse is destroyed, the maximum number of fleeing units is now

    points. Also, no longer calculate score for a defeated player.

  - Fixed a bug where higher-level workers wouldn't occupy lower-level workers'

    working position slots in productionsites

  - The port now conquers every location where its military influence is higher

    than the influence of other players. This fixes a segfault when all

    potential portdock fields are owned by another player, but there is a

    portdock location available where the player owning the port has highest

    influence.

  - Fixed bug in collectors script where a broken message was sent after the

    game ended

                        after all fish is caught

### User Interface

  - Maps can now be zoomed using the mouse wheel or keyboard keys: CTRL+, CTRL-

    to in-/decrease, and CTRL+0 to reset. This also removes 0 as a possible

    landmark number.

  - All map transitions like jumping in messages and in the buildings menu are

    now animated. New commandline option "animate_map_panning".

                        enemy conquers it by sending a notification.

### Internationalization

  - Removed building names from confirmation messages, as they cause grammar

    problems in some languages.

  - Production program descnames can now be fetched by pgettext as well as plain

    gettext.

  - Deleted unused networking messages and unified the "Something went wrong"

    message.

  - Added a Python script to do automated glossary checks for translations. It

    enlists the help of Hunspell and 'misuses' the Transifex note field in order

    to reduce noise.

  - Implemented glossary generation for the Transifex glossary with help from

    the Translate Toolkit (http://toolkit.translatehouse.org/).

  - Show translation stats next to the language selection menu and invite

    translators if a translation is incomplete, with the help of the Translate

    Toolkit. New utils script "update_translation_stats.py" that will write

    translation statistics to data/i18n/translation_stats.conf and is called

    on every translation pull.

### Graphics Engine

  - Renamed "sub" tag to "div" in new font renderer.

  - The new font renderer now sets the width properly and supports player color

    for images. Added width property to img tag

  - The new font renderer now creates a set of textures that will be blitted

    separately by the new class RenderedText. This avoids issues with texture

    sizes exceeding the maximum size supported by graphics drivers when

    MultilineTextareas get arbitrarily long.

  - Fixed incorrect layout of divs with width=fill when the previous div is

    wider than 50%

  - Fixed superfluous space characters at beginning and end of lines

  - Implemented text floating around images

  - Messages try to render with the new font renderer first, then fall back to

    the old font renderer for layouting messages that haven't been converted yet

    (and from savegames).

  - All images with player color now receive their color by a common

    playercolor_image function. Available player colors are kept in an array.

  - Replaced raw pointers in the font renderer with shared_ptr

  - Split graphics into multiple Cmake libraries.

  - Got rid of EdgeOverlayManager and FieldOverlayManager and shifted their

    functionality to local draw() functions in individual classes. Gave the

    Interactive* classes their own draw() functions.

  - Refactored Tcoords, Fcoords and TriangleIndex

  - Fixed bug #1674243: Assign owners to neighbors in Player::rediscover_node.

                        The lack of owners was causing crashes with the road

                        program, which no longer knew which texture to pick.

  - Fixed bug #1711816: Black terrains on fullscreen switch.

### Networking

  - Replaced SDL-Net with Boost.Asio

  - Added IPv6 support

  - Implemented a relay server. Opening a router port is no longer necessary

    for the host of internet games

  - Improved the online login code by adding semi-constant user ids that are

    valid for 12 hours, allowing to reclaim a username after a disconnect

  - Increasing password security by no longer storing and transmitting it in

    plaintext

  - Fixed bug #1691335: Multiplayer client crashes when the host hasn't selected

                        a map yet

### Build System

  - Windows builds now have a unique app id for every build. This allows

    parallel installation of several versions.

  - Modernized how Mac OS X releases are done.

  - Added support for gcc7.

  - Removed "redundant-decls" flag for Windows builds due to conflict between

    SDL and MinGW.

  - New Macro FALLS_THROUGH; for use in switch statements.

    clang-format and pyformat.

  - Fixed a series of compiler warnings for clang and Windows.

  - The ProductionSiteDescr constructor still contained some checks from the

    time when they used to inherit from MilitarysiteDescr. Removed this obsolete

    code and made working_positions and programs mandatory.

  - Used the Notification system to reduce some code interdependency.

  - Various code cleanups to make the code more readable.

  - Fixed diverse crashes and memory leaks with the help of AddressSanitizer

  - Diverse refactorings to use composition over inheritance and to get rid of

    multiple inheritance

  - Replaced SyncCallback through a std::function<void()>.

  - More widespread use of smart pointers

  - Detangled MapView and InteractiveBase.

### Help and Documentation:

  - Generic in-game and in-editor help system driven by Lua scripts. All values

    except for performance are now read from the current Lua configuration

    files.

  - Added some performance values for the buildings help text

  - Improved documentation: Started adding Tribe and World information to our

    online Widelands Scripting Reference.

  - Created a new executable 'wl_map_object_info' that will generate JSON files

    for updating the encyclopedia on the website.

### Graphics Engine

  - Fixed line drawing by replacing the broken use of GL_LINES with a

    tessellation algorithm for drawing lines.

  - Decoupled UI update frequency from game update frequency (which is now 15

    times per second).

  - Removed graphic::update() and Panel::update() and always redraw at maxfps.

  - Changed default maxfps to 30 (instead of 25).

  - Filter all textures linearly instead of near. This looks nicer and texture

    bleeding has been taken care of.

  - Added a new undocumented command line argument --debug_gl_trace which will

    log every OpenGL call that is made, together with arguments, return values

    and glError status. This requires that Widelands is build using

    -DOPTION_USE_GLBINDING:BOOL=ON. It is a NoOp for GLEW. This will help

    debugging non-reproducible OpenGL errors that are reported. Tested with

    glbinding 1.1.0.

  - More logging when OpenGL is initialized.

  - Correctly crop destination and source rectangle while blitting.

  - Fixed memory leaks in UI::Table::draw and around code found using the Leaks

    tool in Apple's Instruments.

                        transparency.
