+# 4.1.0
+
+Saves from 4.0.0 are compatible with 4.1.0.
+
+## Features/Improvements
+
+* **[Campaign]** Air defense sites now generate a fixed number of launchers per type.
+* **[Campaign]** Added support for Mariana Islands map.
+* **[Campaign AI]** Adjustments to aircraft selection priorities for most mission types.
+* **[Engine]** Support for DCS 2.7.4.9632 and newer, including the Marianas map, F-16 JSOWs, NASAMS, and Tin Shield EWR.
+* **[Flight Planning]** CAP patrol altitudes are now set per-aircraft. By default the altitude will be set based on the aircraft's maximum speed.
+* **[Flight Planning]** CAP patrol speeds are now set per-aircraft to be more suitable/sensible. By default the speed will be set based on the aircraft's maximum speed.
+* **[Mission Generation]** Improvements for better support of the Skynet Plugin and long range SAMs are now acting as EWR
+* **[Mods]** Support for version v1.5.0-Beta of Gripen mod. In-progress campaigns may need to re-plan Gripen flights to pick up updated loadouts.
+* **[Plugins]** Increased time JTAC Autolase messages stay visible on the UI.
+* **[Plugins]** Updated SkynetIADS to 2.2.0 (adds NASAMS support).  
+* **[UI]** Added ability to take notes and have those notes appear as a kneeboard page.
+* **[UI]** Hovering over the weather information now dispalys the cloud base (meters and feet).
+* **[UI]** Google search link added to unit information when there is no information provided.
+* **[UI]** Control point name displayed with ground object group name on map.
+* **[UI]** Buy or Replace will now show the correct price for generated ground objects like sams.
+* **[UI]** Improved logging for frontline movement to be more descriptive about what happened and why.
+* **[UI]** Brought ruler map module into source, which should fix file integrity issues with the module.
+
+## Fixes
+
+* **[Campaign]** Fixed the Silkworm generator to include launchers and not all radars.
+* **[Data]** Fixed Introduction dates for targeting pods (ATFLIR and LITENING were both a few years too early).
+* **[Data]** Removed SA-10 from Syria 2011 faction.
+* **[Economy]** EWRs can now be bought and sold for the correct price and can no longer be used to generate money
+* **[Flight Planning]** Helicopters are now correctly identified, and will fly ingress/CAS/BAI/egress and similar at low altitude.
+* **[Flight Planning]** Fixed potential issue with angles > 360° or < 0° being generated when summing two angles.
+* **[Mission Generation]** The lua data for other plugins is now generated correctly
+* **[Mission Generation]** Fixed problem with opfor planning missions against sold ground objects like SAMs
+* **[Mission Generation]** The legacy always-available tanker option no longer prevents mission creation.
+* **[Mission Generation]** Prevent the creation of a transfer order with 0 units for a rare situtation when a point was captured.
+* **[Mission Generation]** Planned transfers which will be impossible after a base capture will no longer prevent the mission result submit.
+* **[Mission Generation]** Fix occasional KeyError preventing mission generation when all units of the same type in a convoy were killed.
+* **[Mission Generation]** Fix for AAA Flak generator using Opel Blitz preventing the mission from being generated because duplicate unit names were used.
+* **[Campaign AI]** Transport aircraft will now be bought only if necessary at control points which can produce ground units and are capable to operate transport aircraft.
+* **[UI]** Statistics window tick marks are now always integers.
+* **[UI]** Statistics window now shows the correct info for the turn
+* **[UI]** Toggling custom loadout for an aircraft with no preset loadouts no longer breaks the flight.

 # 4.0.0
 
 Saves from 3.x are not compatible with 4.0.
 
 ## Features/Improvements
 
-* **[Campaign]** Squadrons now have a maximum size and killed pilots replenish at a limited rate.
+* **[Engine]** Support for DCS 2.7.2.7910.1 and newer, including Cyprus, F-16 JDAMs, and the Hind.
+* **[Campaign]** Squadrons now (optionally, off by default) have a maximum size and killed pilots replenish at a limited rate.
 * **[Campaign]** Added an option to disable levelling up of AI pilots.
+* **[Campaign]** Added Russian Intervention 2015 campaign on Syria, for a small and somewhat realistic Russian COIN scenario.
+* **[Campaign]** Added Operation Atilla campaign on Syria, for a reasonably large invasion of Cyprus scenario.
 * **[Campaign AI]** AI will plan Tanker flights.
 * **[Campaign AI]** Removed max distance for AEW&C auto planning.
 * **[Economy]** Adjusted prices for aircraft to balance out some price inconsistencies.
 * **[Factions]** Added more tankers to factions.
 * **[Flight Planner]** Added ability to plan Tankers.
+* **[Modding]** Campaign format version is now 7.0 to account for DCS map changes that made scenery strike targets incompatible with existing campaigns.
 * **[Mods]** Added support for the Gripen mod.
+* **[Mods]** Removes MB-339PAN support, as the mod is now deprecated and no longer works with DCS 2.7+.
 * **[Mission Generation]** Added support for "Neutral Dot" label options.
+* **[New Game Wizard]** Mods are now selected via checkboxes in the new game wizard, not as separate factions.
 * **[UI]** Ctrl click and shift click now buy or sell 5 or 10 units respectively.
 * **[UI]** Multiple waypoints can now be deleted simultaneously if multiple waypoints are selected.
 * **[UI]** Carriers and LHAs now match the colour of airfields, and their destination icons are translucent.
 * **[UI]** Updated intel box text for first turn.
+* **[UI]** Base Capture Cheat is now usable at all bases and can also be used to transfer player-owned bases to OPFOR.
+* **[UI]** Pass Turn button is relabled as "Begin Campaign" on Turn 0.  
+* **[UI]** Added a ruler to the map.
+* **[UI]** Liberation now saves games to `<DCS user directory>/Liberation/Saves` by default to declutter the main directory.
 
 ## Fixes

-* **[Campaign AI]** Improved pruning of unplannable missions which should improve turn cycle time and prevent the auto-planner from quitting early.
+* **[Campaign AI]** Fix auto purchase of aircraft for factions that have no transport aircraft.
+* **[Campaign AI]** Fix refunding of pending aircraft purchases when a side has no factory available.  
 * **[Mission Generation]** Fixed problem with mission load when control point name contained an apostrophe.
 * **[Mission Generation]** Fixed EWR group names so they contribute to Skynet again.
 * **[Mission Generation]** Fixed duplicate name error when generating convoys and cargo ships when creating manual transfers after loading a game.
+* **[Mission Generation]** Fixed empty convoys not being disbanded when all units are killed/removed.
+* **[Mission Generation]** Fixed player losing frontline progress when skipping from turn 0 to turn 1.
+* **[Mission Generation]** Fixed issue where frontline would only search to the right for valid locations.
 * **[UI]** Made non-interactive map elements less obstructive.

+
+        Turn initialization performs all of the beginning-of-turn actions. *End-of-turn*
+        processing happens in `pass_turn` (despite the name, it's called both for
+        skipping the turn and ending the turn after combat).
+
+        Special care needs to be taken here because initialization can occur more than
+        once per turn. A number of events can require re-initializing a turn:
+
+        * Cheat capture. Bases changing hands invalidates many missions in both ATOs,
+          purchase orders, threat zones, transit networks, etc. Practically speaking,
+          after a base capture the turn needs to be treated as fully new. The game might
+          even be over after a capture.
+        * Cheat front line position. CAS missions are no longer in the correct location,
+          and the ground planner may also need changes.
+        * Selling/buying units at TGOs. Selling a TGO might leave missions in the ATO
+          with invalid targets. Buying a new SAM (or even replacing some units in a SAM)
+          potentially changes the threat zone and may alter mission priorities and
+          flight planning.
+
+        Most of the work is delegated to initialize_turn_for, which handles the
+        coalition-specific turn initialization. In some cases only one coalition will be
+        (re-) initialized. This is the case when buying or selling TGO units, since we
+        don't want to force the player to redo all their planning just because they
+        repaired a SAM, but should replan opfor when that happens. On the other hand,
+        base captures are significant enough (and likely enough to be the first thing
+        the player does in a turn) that we replan blue as well. Front lines are less
+        impactful but also likely to be early, so they also cause a blue replan.
+
+        Args:
+            for_red: True if opfor should be re-initialized.
