---------------------------

   (from <https://www.freeciv.org/wiki/NEWS-3.0.6>, 2023-02-02)

3.0.6 is a bugfix release in freeciv-3.0 series. The focus has been
in supporting current bleeding edge systems, to make freeciv compatible
with latest releases of other components and tools.

Server / General

    * When the worklist item cannot be currently built, server now detects
      more cases where it will be impossible to ever build it and purges
      the worklist item instead of just postponing osdn#45563
    * Silenced some unused entry warnings when loading saved games osdn#46144
    * Freeciv now uses new libcurl API, instead of one deprecated in
      latest versions, to communicate with the metaserver and,
      in case of modpack installer, to fetch files osdn#46345
    * When starting from a saved game, dead players are no longer
      counted towards ready/unready player counts in pre-game osdn#44621
         + Dead players do not affect whether game can start or not
           (no need to wait for them)
         + Gtk- and Qt-clients' pre-game dialog "Start" button is
           never sensitive when the client is attached to a dead player

CHANGES FROM 3.0.2 to 3.0.3
---------------------------

   (from <https://www.freeciv.org/wiki/NEWS-3.0.3>, 2022-08-05)

3.0.3 is a bugfix release.

There's a vulnerability fixed in modpack installer. All users
of older versions are adviced to upgrade.

Default metaserver connection URL and URL used to fetch default modpack list
have been updated to use https -protocol. This should cause no problems if
https has been working for you all the time. However, if it was already broken
(e.g. you couldn't download modpacks located on https even with earlier freeciv
version), this makes the problem worse for you. The most likely cause for any
problems with https is that root certificates (cacerts) are not set up properly.
From freeciv side, building with the configuration option --with-cacert-path
may help. In case everything else fails, we provide, for now, a .project file
that you can use to build freeciv so that metaserver and modpack list
default URLs still use http:
--with-project-definition=<freeciv srcdir>/bootstrap/http.project
We won't support that on freeciv-3.1.

Server / General
Changes affecting players (supplied rulesets)

    * Ransom is given for each barbarian leader when there's more
      than one in the same tile (but no other units to defend them).
      The old behavior was not to give ransom at all as they were
      considered to be defending each other. osdn#42020
    * Fixed server setting tradeworldrelpct to affect also
      the initial one time bonus of the trade route. osdn#42097

      It used to always claim that load was succesfull to the client

      unit obsoletion loop osdn#42301

         + civ2civ3 only Welcome message points directs user to find
           more information from About Current Ruleset osdn#42329
         + Reworked the way labels get assigned to the map
           when it's generated osdn#42708

         + Clean format by always setting irrigation_time / plant_time
           to zero when the activity in question is disabled by
           relevant _result field. This does not change how
           the ruleset behaves, but is less confusing to read osdn#42211

    * italy scenario
         + Wrap map from the correct point so that leftmost part
           of the map is connected to the rest HRM#691812

    * british isles scenario
         + Scenario now uses nationset all, so the correct nations
           from the isles are available and get placed,
           instead of completely random nations from the core nationset
           osdn#42939

Changes affecting other rulesets / modders
