NEWS-3.2.0

Edit

This list is still in preparation; 3.2.0 has not yet been released.

Welcome to Freeciv 3.2.0[]

Thanks again to all our developers, who continue to work so hard.

This release includes lots of changes relative to 3.1.x; the significant ones are outlined below. Bug fixes also included in the 3.1 line are not listed. Those who are interested in seeing the detailed changes should check the ChangeLog file, linked above.

This release is still in a beta stage, so there are some known issues (see below).

WHAT'S CHANGED SINCE 3.1[]

The major changes in 3.2 are gtk4-client as default, new sdl3-client, meson based build system as default, and a whole lot of extra flexibility to create custom rulesets.

As is usual for major releases, 3.2 clients cannot interoperate with pre-3.2 servers, and vice versa. Most pre-3.2 savegames can however be loaded into 3.2, and in most cases, the supplied rulesets have not changed so much as to make it difficult to complete a game started with 3.1.x's rules.

Server / General[]

  • gtk4-client is now the default osdn#47782
  • gtk3-client has been discontinued. gtk3.22-client still exist. osdn#41531
  • New sdl3-client osdn#48820
