WHAT'S CHANGED SINCE 2.6.0-BETA2[]

Beta3 is mainly a bugfix release. Notably, it should fix crashes in the Windows Gtk clients when moving or resizing dialogs, and the default Gtk3 client now draws animations in a new way which is less laggy.

Server / General[]

Changes affecting players (supplied rulesets)[]

Units were prevented from moving between transports on different tiles in some circumstances. HRM#693380
In the Gtk3.x and Qt clients, it's now possible to move a unit between transports on the same tile. HRM#732489
Stealing a future technology was accidentally yielding two of them. HRM#736836
Units can no longer help to build small wonders such as the Palace. (However, this is likely to be reverted before 2.6.0; see known issues.) HRM#705580
Fix a cause of error messages like "Team 0 had invalid technology goal" when loading savegames with AI players. HRM#695971
Put a message about nuclear attack in a more appropriate category. HRM#735934
The tutorial scenario was not displaying messages about technology if you acquired them by means other than research (for instance, from a hut). HRM#657359
Changes to the civ1 ruleset to improve its fidelity:
- It's no longer possible to know a tech without its prerequisites. HRM#729171
- Adjusted the progress of years to be more like the original. HRM#731631

Changes affecting other rulesets / modders[]

More checking (and documentation) of the relationship between extra and base/road sections in the ruleset. HRM#736838 HRM#736837
Fix a crash with a malformed tileset. HRM#729532
Remove any special handling of terrain name "unused" (which hasn't done anything useful for some time). HRM#707585
The new help system for extras works best if their main effect clause is simplified and any special cases moved to subsidiary clauses; this particularly affects the standard pattern of irrigation and farmland effects. 2.6 ruleset authors may wish to compare their effects.ruleset to the changes in supplied rulesets; without these changes, the terrain help may not show the bonuses of your extras.
The onus is now on rulesets to describe the effects of irrigation, mining, and pollution if relevant. 2.6 ruleset authors may wish to change their help in line with the changes to supplied rulesets.

General[]

Fix an erroneous diagnostic for a malformed savegame. HRM#729275
Fix a minor server memory leak. HRM#735637
Various internal changes which should only affect developers. HRM#715161 HRM#730564 HRM#696674 HRM#729900 HRM#733792 HRM#735850 HRM#735940 HRM#740444

Clients[]

The Windows builds of the Gtk clients tended to crash when certain dialogs were moved or resized. This was a regression since beta1. (This fix unfortunately leads to the rubber-band selection rectangle in the Windows Gtk3 client becoming uglier.) HRM#735238
Less laggy animations in the Gtk3 client (these were already in Gtk3.22). However, map scrolling animation is still absent. HRM#726552
In the city dialog, clicking on the middle tile to rearrange workers could fail to update the city dialog map display. HRM#736822
Music system: in-game music could be played even after leaving a game. HRM#730597
Give error messages when the tileset specified with the --tiles command-line option, or suggested by the ruleset, can't be loaded. HRM#730777 HRM#657414
Gtk3.22: when a unit died while the client was still showing its earlier movement (for instance when attacking), the animation of its movement was not shown fully. HRM#737277
Gtk3.22: remove some spurious underscores from UI element names. HRM#719507
SDL2: fix "Unable to create Sprite" errors on console when city dialog is opened. HRM#684183

Tools[]

The ruleset editor statistics now include the number of multipliers. HRM#735246

Tilesets / Art[]

Updates for the Hexemplio/Toonhex tilesets: hex-shaped forts/fortresses and city walls, less obtrusive ruins, and improved water. HRM#729151 HRM#729137 HRM#731454
Less obtrusive ruins in Amplio2. HRM#697692
Other very minor tileset tweaks. HRM#692596 HRM#729141

Help / Documentation[]

The built-in help now fully covers the updated 2.6 terrain improvement and conversion system and corresponding ruleset features. Some errors in the already existing help were also fixed. HRM#732512 HRM#733895 HRM#733989 HRM#657410 HRM#732507 HRM#733863 HRM#733865 HRM#733902 HRM#736795 HRM#736830 HRM#736833
The help for the 'sandbox' ruleset now notes that savegames may not be portable even between minor releases. HRM#732480
Miscellaneous improvements to in-game text and user documentation. HRM#699164 HRM#696673 HRM#691877 HRM#660409 HRM#733864 HRM#733913 HRM#733929 HRM#730586
Miscellaneous changes to developer/ruleset docs. HRM#732479 HRM#699149 HRM#736837 HRM#738322 HRM#738321 HRM#738908 HRM#740593

Translations[]

Updated translations:
- Complete translations: Russian.
- Incomplete translations: Catalan (100% core, 100% nations, 98.2% ruledit), Polish (99.6% core, 100% nations, 98.2% ruledit), Finnish (98.5% core, 91% nations, 98.2% ruledit), British English (95.1% core, 100% nations, 100% ruledit).

Build/portability[]

Fix a possible failure to build the Qt client (undefined reference to SDL_main), observed on Mac OS X Sierra. HRM#734798
We now recommend that packagers favor the Gtk3.22 client over the Gtk3 one. HRM#726799
The supplied appdata .xml files have been updated to a more modern format. HRM#690231
The appdata .xml file for the Gtk3.22 client referred to the wrong .desktop file. HRM#738290
Fix some compiler warnings with Clang 6.0 HRM#733013 and GCC 8 HRM#731162.

Known issues[]

The rule change which disallows caravans/freight from helping build small wonders breaks the multiplayer ruleset, where most wonders are small wonders. We may revert it from 2.6 and postpone to 3.0. HRM#745360
The Gtk3 clients currently don't have animation for moving the map view. HRM#735217
The right-click map selection rectangle in the supplied Windows Gtk3 package is ugly and leaves trails behind on the map view. HRM#736230
