This is not a full changelog. Only most recent versions are listed.
Many features stopped working after switching IL-2 versions, and had to be reimplemented again, thus they appear in more than one version.

############ WarBirds FreeHost version 3.33 (IL-2 4.12.2+HSFX7) ############
- squad functionality is back
- implemented a squad channel in chat
- added colors to chat for squad and server messages
- fixed dropping of cargo - now it drops one by one as all other loads
- reimplemented "changed bomb and rocket ballistics back to 4.09m version; bombs and rockets have greater accuracy, level bombing is now possible with good precision, rockets will fly with more straight trajectory"
- reimplemented "changed bomb explosion logic back to 4.09m version; bombs can destroy targets even if they hit a few meters from them, it is no longer required to hit a building directly to destroy it (using a big bomb)"
- reimplemented "changed (increased) firepower and radius of MGunM4_75 (B25H) and MGunBK75 (HS129) guns to values of a 30kg bomb. This makes these guns more useful when attacking ground targets."
- fixed a bug introduced with AutoTrim, which disabled the "rudder left" key setting
- disabled recording of quick tracks and making screenshots in game; this should help against on demand warping
- implemented the Transferring Mission Bug fix
- added this changelog ;)

############ WarBirds FreeHost version 2.20.5a (IL-2 4.11.1+HSFX6) ############
- fix for bug appearing after map reset (losing side had aircraft of both sides available)


############ WarBirds FreeHost version 2.20.5 (IL-2 4.11.1+HSFX6) ############
- changed bomb and rocket ballistics back to 4.09m version; bombs and rockets have greater accuracy, level bombing is now possible with good precision, rockets will fly with more straight trajectory
- changed bomb explosion logic back to 4.09m version; bombs can destroy targets even if they hit a few meters from them, it is no longer required to hit a building directly to destroy it (using a big bomb)
- implemented AutoTrim feature; this is like Level Stabiliser, but it keeps the plane in constant, sustained climb (requires setting up a new key); NOTE: this also introduced a bug, which removed "rudder left" key setting. This was fixed in version 3.33.


############ WarBirds FreeHost version 2.20.4a (IL-2 4.11.1+HSFX6) ############
- fix for on-line score not being displayed after previous release


############ WarBirds FreeHost version 2.20.4 (IL-2 4.11.1+HSFX6) ############
- reimplemented Cargo
- fix for HSFX6 109 cockpit bug (bouncing after hitting ground)
- ReFly is automatically done 10s after being killed (prevents viewing map after death)
- reimplemented "removed plane markings from on-line score"
- take-off restrict is now applied only after death, is not applied after being damaged (time limit to take off from a field, where pilot was killed shortly after take-off)
- available plane markings can now be configured for each map, for Red and Blue sides separately. Maps only include proper markings - Luftwaffe/RAF, USA/Japan, Luftwaffe/USSR etc. No longer possible to fly with wrong markings.
- new paratrooper counting logic when capturing fields (fix for improper counting sometimes)
- different number of paras needed to capture each field type:
   - small field: 9 paras
   - medium field: 15 paras
   - big field: 30 paras
Now every taxi can capture at least 2 small fields in one sortie. Also big fields require two taxis.
- improved mission loading times
- several changes on server side: support for new maps, improved stability
- added support for proper separate bomber and fighter scores


############ WarBirds FreeHost version 2.20.3 (IL-2 4.11.1+HSFX6) ############
- enabled outside views for bombers
- made bombers impossible to ram (attacker dies, bomber is unharmed)
- disabled collisions on take-off (altitude < 100m and speed < 100km/h)
- modified inflight mini map to show field names and proper field icons
- all radar circles on the map are now white all the time - it is not possible to see when radar is destroyed by looking at the map
- possible to drop bombs, rockets, cargo and paratroopers one by one
- changed (increased) firepower and radius of MGunM4_75 (B25H) and MGunBK75 (HS129) guns to values of a 30kg bomb. This makes these guns more useful when attacking ground targets.
- fix for <field command, now it shows destroyed targets and the time in which they will 'reup'
- landing with an undamaged plane on an enemy field now properly counts as being captured


############ WarBirds FreeHost version 2.20.2 (IL-2 4.11.1+HSFX6) ############
- small bug fixing update (difficulty settings)


############ WarBirds FreeHost version 2.20.1 (IL-2 4.11.1+HSFX6) ############
