+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+# 2.4.0
+
+Saves from 2.3 are not compatible with 2.4.
+
+## Highlights
+
+* Improved flight plan generation to avoid loitering in or traveling through threatened areas when practical.
+* Improved AI aircraft purchasing behavior.
+* Era-restricted weapons (work in progress).
+* Tons of UI polish.
+* Rebalanced economy to keep opfor competitive over the course of the game.
+
+## Features/Improvements
+
+* **[Flight Planner]** Air-to-air and SEAD escorts will no longer be automatically planned for packages that are not in range of threats.
+* **[Flight Planner]** Non-custom flight plans will now navigate around threat areas en route to the target area when practical.
+* **[Flight Planner]** Flight plans along front lines now ensure that the race track start is closer to the departure airfield than the race track end.
+* **[Campaign AI]** Auto-purchase now prefers airfields that are not within range of the enemy.
+* **[Campaign AI]** Auto-purchase now prefers the best aircraft for the task, but will attempt to maintain some variety.
+* **[Campaign AI]** Opfor now sells off odd aircraft since they're unlikely to be used.
+* **[Campaign AI]** Multiple rounds of CAP will be planned (roughly 90 minutes of coverage). Default starting budget has increased to account for the increased need for aircraft.
+* **[Mission Generator]** Multiple groups are created for complex SAM sites (SAMs with additional point defense or SHORADS), improving Skynet behavior.
+* **[Mission Generator]** Default start type can now be chosen in the settings. This replaces the non-functional "AI Parking Start" option. **Selecting any type other than cold will break OCA/Aircraft missions.**
+* **[Cheat Menu]** Added ability to toggle base capture and frontline advance/retreat cheats.
+* **[Skynet]** Updated to 2.0.1.
+* **[Skynet]** Point defenses are now configured to remain on to protect the site they accompany.
+* **[Hercules]** Updated the Hercules Cargo list file.
+* **[Balance]** Opfor now gains income using the same rules as the player, significantly increasing their income relative to the player for most campaigns.
+* **[Balance]** Units now retreat from captured bases when able. Units with no retreat path will be captured and sold.
+* **[Economy]** FOBs generate only $10M per turn (previously $20M like airbases).
+* **[Economy]** Carriers and off-map spawns generate no income (previously $20M like airbases).
+* **[Economy]** Sales of aircraft and ground vehicles can now be cancelled before the next turn begins.
+* **[UI]** Multi-SAM objectives now show threat and detection rings per group.
+* **[UI]** New icon for AA sites with no active threat.
+* **[UI]** Unit names are now prettier and more accurate, and can now be set per-country for added historical flavour.
+* **[UI]** Default loadout is now shown for flights with no custom loadout selected.
+* **[UI]** Aircraft for a new flight are now only selectable if they match the task type for that flight.
+* **[UI]** WIP - There is now a unit info button for each unit in the recruitment list, that should help newer players learn what each unit does.
+* **[UI]** Docs for time-on-target and creating new theaters/factions/loadouts are now linked in the UI at the appropriate places.
+* **[UI]** ASAP is now a checkbox rather than a button. Enabling this will disable the TOT selector but changes to the package structure will automatically re-ASAP the package.
+* **[UI]** Arrival airfield is now shown in the flight list if it differs from the departure airfield.
+* **[UI]** Start type can now be selected when creating a flight.
+* **[UI]** Arrival and divert airfields can be edited after the flight is created.
+* **[Factions]** Added option for date-based loadout restriction. Active radar homing missiles are handled, patches welcome for the other thousand weapons.
+* **[Factions]** Added Poland 2010 faction.
+* **[Factions]** Added Greece 2005 faction.
+* **[Factions]** Added Iran 1988 faction.
+* **[Units]** Support for E-2 Hawkeye, SH-60B Seahawk, S-3B Viking (thanks to awinterquest) and SpGH Dana - these are now being used by appropriate factions.
+* **[Culling]** Missile sites are no longer culled.
+* **[Campaigns]** Added campaign "Black Sea Lite" by Starfire
+* **[Campaigns]** Added campaign "Exercise Vegas Nerve" by Starfire 
+* **[New game Wizard]** The theater page is now the first page of the campaign wizard, recommended factions will be selected automatically on the faction selection page
+* **[New game Wizard]** Added information text about the selected campaign performance.
+* **[Mod Support]** Added support for High Digit SAMs mod 1.4.0
+* **[Mod Support]** Added SAMs sites generator : KS19Generator, SA10BGenerator, SA12Generator, SA17Generator, SA20Generator, SA20BGenerator, SA23Generator    
+
+## Fixes
+
+* **[Hercules]** Updated the default Hercules radio frequency.
+* **[Economy]** Pending unit orders at captured bases will be refunded.
+* **[UI]** Carrier group SAM threat rings now move with the carrier.
+* **[UI]** Base intel menu no longer compresses text, and is now scrollable.
+* **[UI]** Edit Flight window is now dynamically sized to adapt to the width of waypoint names, so they no longer get truncated.
+* **[UI]** Budget income display is now rounded to 2 decimal places.
+* **[UI]** Fixed incorrect income per turn displayed for strike target tooltip.
+* **[Factions]** USA with C-130 faction now links to the required mod.
+* **[Campaign]** Fixed issue where destroyed buildings would sometimes not count as destroyed and thus respawn.
+* **[Campaign]** Fixed issue where destroyed runways were not registered.
+* **[Units]** J-11A is no longer spawned with empty loadout.
+* **[Units]** F-14B is no longer spawned with empty loadout for fighter sweep tasks.
+* **[Units]** Pyotr Velikiy cruiser has been removed for now as it's nearly unkillable.
+* **[Units]** Submarines have been removed for now as they aren't wholly functional.
+* **[Units]** Fixed "FACTION ERROR : Unable to find OliverHazardPerryGroupGenerator in pydcs" error at startup.
+* **[Mission Generator]** Fixed a bug where units set to Aggressive stance sometimes did not move.
+* **[Mission Generator]** Flyover points for OCA/Aircraft missions are now generated correctly.
+* **[Flight Planner]** Fixed not being able to create custom waypoints for buildings.
+* **[Flight Planner]** Strike missions will no longer be automatically planned against SAMs.
+* **[Flight Planner]** Strike missions will no longer be automatically planned against FOB structures.
