r21085 Implement rmgen SlopeConstraint? which is met if the elevation difference is within the given range.
r21182 Implement ElevationBlendingPainter? which interpolates the height of the given area with the desired height.
r21224 Area getClosestPointTo helper function that allows dock placement on random maps without preknowledge about the water location.
r21225 Implement a DiskPlacer? to enable random map scripts chosing all points inside a circle without using a special case of the other placers.
r21289 Separate object-oriented random map generation core library "rmgen" from miscellaneous helper procedures which are moved to a new library "rmgen-common".
r21485 CityPainter? for random map scripts that fills the given area randomly with the given templates.

Tutorial Maps

r20084, r20085, r20086 Convert the Introductory Tutorial to a tutorial map
r19998 Fix tuturial being stuck (#4696, #4697)
r20778 Replace the hardcoded keynames of the Introductory Tutorial strings with the sprintf solution from. Remove hardcoded default batch training size and GUI row count hint (which could have become invalidated too easily).

Renderer

r20001 Shadow map quality option (#4351, #743)
r20378 Adds a wireframe mode to the water rendering.
r20583 Reload water shaders too when changing shader settings.
r20622 Render the range visualization of auras, heal and attack component in a separate RangeOverlayRenderer? component instead of abusing Selectable for that. This also allows non-selectable entities like building previews to cast range visualizations.
r21291 Added multiples UVs to animated model.

Preparation for Isometric view

r20377 Adds a perspective matrix, refracts a matrix projection setup to prepare for an isometric view.

Lobby

r20776 Support both DateTime? formats of XEP-0082 in the lobby.
r20868 Don't crash while in the lobby when receiving an error IQ stanza without an error payload.
r20886 Enable players to open the lobby as a dialog in the gamesetup, running games and the summary screen.
r20958 Implement an auto-scroll setting for GUI lists.This allows the replay menu and lobby to focus the selected element if, but only if it is expected by the user.
r20960 Only initially focus the chat input in multiplayer gamesetup, so that the Tab hotkeys new in are immediately available in singleplayer. Also, focus the chat after having clicked the Send button.
r20967 Add civ settings in lobby for the selected game.
r21003 Unify Gamesetup/Lobby? Chat Design.
r21263 Add the lobby button to the summary screen.
r21301 Check lobby games for incompatible mods.
r21311 Adds remember password checkbox.
r21718 Lobby Bot Optimizations and Upgrade to recent SleekXMPP/ejabberd versions.
r21719 Send rating related requests directly to EcheLOn.
r21720 Update mod_ipstamp for current ejabberd versions and update lobby setup instructions.
r21742 Allow lobby players to watch the replay of the game just played without disconnecting them from the lobby, because they can open the lobby as a dialog while replaying the game in this release.
r21761 Ask the lobby player to open the mod selection page if the mods don't match the ones from the lobby host.

Network

r20321 Add id for IQ stanzas
r20341 The server should choose the guid
r20557 Don't display a timestamp when an invalid command is sent
r21023 Don't trigger a NetServerTurnManager? debug breakpoint if a modified or unmodified client sends a non-sequential turnnumber. Disconnect that client.
r21520 Secure lobby authentication - prevent joins as a different player.

Engine/Modding

r19951 (and a few more later) Allow the AI to load custom templates (follow-up to #2951)
r19952 Allow using {civ} in builder lists when some civs don't have those templates without errors
r20035 Fix an assertion failure when closing the game in the map loading screen (#4154)
r20067 Add a window icon (#4363)
r20120 Allow specifying the gravity affecting projectiles

This allows for different flight paths (eg mortars, magical projectiles).

To keep the same behavior as previous iterations of the game add <Gravity>9.81</Gravity> to the <Attack> tags of your templates.

r20141 Add -unique-logs parameter to make debugging of OOS issues locally easier
r20181 Move placeable templates out of special/.

Specifically special/territory_pull is now other/territory_pull, and special/trigger_point_[A-K] are trigger/trigger_point_[A-K], update your map xml files and trigger scripts accordingly.

This is part of a change from a placeable filter approach (where one has to explicitly list all folders/templates that can be placed in the atlas) to an unplaceable filter approach. This should make it easier for modders to use a different folder structure than the public mod, and have it work without any changes. We assume that adding unplaceable templates happens less often and that modders will notice if they can suddenly place something they added that shouldn't be placeable.

r20196 Add FloatDepth property to Position.

This allows to have amphibious units that swim at a certain depth.

To keep the current behavior add <FloatDepth>0.0</FloatDepth> to all <Position> tags of your templates (probably as high up in the inheritance hierarchy as possible).

r20203 Move damage types definition to a helper similar to how resources are handled.

This should make it somewhat easier to add new damage types. (See #4801 for more improvements.)

r20204 Delayed damage. Can be used for grenades or similar. (#1911)

To keep the current behaviour for ranged attacks add <Delay>0</Delay> to the <Ranged> tag of your <Attack> tags.

r20215 Remove special_units/ by using inheritance.
r20241 Move formation templates from formations/ to special/formations.

Part of the placeable/unplaceable restructuring.

Make the same moves for your mods, also update all templates specifying formations (<Formations> tag within <Identity> tags).

Update your civ.json files. Prefix special/ for all entries in the "Formations" property array.

r20242 Move special_filter/ templates to special/filter/.

Move any filters you have in your mod to the new folder.

r20244, r20252 Make rubble non-decaying by default.

If your mod specifies rubble in <SpawnEntityOnDeath> (within <Health>), or elsewhere you should prefix those occurrences with decay|. Specify different decay settings in the individual rubble templates, the decay| filter just activates the decay.

See the commit for a *nix one-liner to make this change for you. (As always check the end result, and use a version control system.)

r20246 Switch back to an unplaceable filter for templates.

This makes rubble/ placeable.

The only unplaceable templates from now on start with template_ or special/. All other templates now show up in Atlas, and in code queries for all templates.

Allows using different template organization schemes (subfolders, different folders, etc).

r20249 Command line options can now start with - or --.
r20589 Amend wallpiece lengths. (#2944)
r20575 Deprecate type property of mods. Such a property should be well defined, but currently, it contains arbitrary text and is redundant with the description. (#4890)
r20614 Support translation of mod labels and description.
r20625 Remove civ-specific hardcoding in rmgen wall-placement script. (#2944)
r20729 Delete Savegame format version, refs rP10454. It is unneeded because we won't add backward compatibility for previous formats and because the engine version check from rP16906 is sufficient and more accurate in testing the compatibility of savegames of different releases. The simpler code allows unifying the savegame version check with the check used by the replay menu (to be used in multiplayer gamesetups).
r20899 add a protection for mods without the expected metadata.
r20939 Garrisoned units are lost after an upgrade towards a non-garrison holder.
r20952 Move domestic animal Cost to the trainable templates.
r21093 Move ruins templates to a new gaia/ruins/ subfolder.
r21094 Move ruins templates from other/ to gaia/ruins/.
r21095 Move gaia/special_treasure_* to gaia/treasure/.
r21239 Check for and save mod version for savegames and replays.
r21723 Define and associate .pyromod filetype with pyrogenesis on Linux and Windows.
r21726 pyrogenesis can now take a zip file (rename it to .pyromod for direct file association following r21723) and install it. It then starts the mod selector.
r21759 mod.io support. mod.io is a new platform for sharing mods, that 0 A.D. can make use of in order to download mods and install them.

Performance Optimizations

r20256 Fix lag from moving to the edge of the map
r20438 Fix lag from sinking ships (#4713)
r19936 Stop copying the territory grid when recomputing the texture.
r20311 Some performance optimizations.
r20438 Use the rangeManager's subdivisions in the obstruction manager shape tests Completes an existing TODO. This is a large speedup in some cases for those test functions, particularly the "sunken ship lag" issue.(#4713)
r20571 Change gathering rally points to use gather instead of gather-near-position when possible.
r20630 Improve Hierarchical Pathfinder Update, somewhat substantially on larger map sizes
r20634 Long range pathfinder cleanup Remove ACCEPT_DIAGONAL_GAPS as it was unused and will not be used in the future. Use PASSABLE macro everywhere. Simplify considerable OnTheWay? as MakeGoalReachable? returns a point goal. This doubles as a very slight optimisation, on the order of microseconds per call.
r20876 Gather near dropsite rather than current position after finishing construction.
r20878 Consider that the point could be inside the goal area in some PathGoal? functions.
r20950 Use correct distance for determining nearest dropsite Use the distance to the nearest point on the dropsite's obstruction rather than the center of the dropsite.
r21019 The gui shouldn't load again needed templates on each turn.
r21088 Accelerate Danubius map generation performance, from 90 seconds to 15 seconds.
r21092 Performance improvement on Kerala.
r21418 Performance improvement for the StaticConstraint? by not initializing the cache upon construction but filling it just-in-time.
r21425 Improve random map script performance by using squared distance where possible.

Libraries Updates

r20340 Update the bundled gloox wrapper for Windows.
r20407 Update Boost to 1.65.1 and provide static libs (built with XP toolset) for upcoming VS 2015 support.(#3004)
r21501 Update libcurl for OSX, in order to fix the build. Use the opportunity to update libxml2 which had vulnerabilities.
r21583 Update some OS X libraries with security fixes and hopefully low regression risks.
r21674 Use libsodium for cryptography.
r21683 Update libcurl to 7.59.0 on Windows and enable SSL support on Windows and macOS.

Profiling

r21602 Simulation replay profiling graph overhaul.
r21694 Ease comparison of two replay profile graphs by typing the filename in the browser instead of renaming the data.json files.

Building scripts and linting

r20364 Linting with Coala. This new script and the associated configuration files lint our source code (JS and C++). This will be extended in the future.(#4833 )
r20365 Add our script for building patches with Jenkins to version control.(#4419)
r20366 Alpha 12 version of Premake 5, including prebuilt binary for Windows .(#3729)
r20381 Migrate to premake5, Make pyrogenesis and tests depend on Collada, This commit includes custom modules for CxxTest? and pkg-config support that can be improved upon in the future. It also includes all necessary changes to the build scripts, but the new premake5 features are not fully exploited yet. With this change, premake5 becomes the default, but CI scripts on Unix will continue using premake4 for a while, in order to avoid regressions.(#3729, #404 )
r20561 Use default Unicode encoding in source code on Windows.
r20562 Support Visual Studio 2015 (MSVC 14.0), VS 2013 stays the default Windows compiler, but support for it will be dropped as soon as possible.(#3439)
r20563 Go back to the legacy syntax for detecting premake actions.
r21389 Enable multi-processor compilation on Windows with premake5.
r21480 Fix compiler warnings on VS 2015.
