 ## Changes:
 
+###### Build 145
+2022-06-26
+Possibly last round of weapon additions!
+@Pecusx added 
+- working White Flag -- it is a way to give up while not making opponents richer!
+- Battery - a must for every tank with low energy.
+- Strong Parachute - like a normal parachute, but stronger (it has energy and can work more than once)
+- Nuclear Winter - a quick and efficient solution to global worming, err, warning, WARMING!
+@mikerro added new SFX and in-game-tunes.
+- Pressing [S] turns on/off SFX (when aiming). Pressing [M] turns on/off in-game tunes.
+Tickets closed:
+- https://github.com/pkali/scorch_src/issues/54 - holding joystick up or down longer speeds up force change. It makes playing with joystick much nicer.
+- https://github.com/pkali/scorch_src/issues/76 - a beginning of visual tweaks by Adam
+- infinite defensive weapons purchase bug fixed, to chagrin of some...
+
+###### Build 144
+2022-06-19
+Father's day release comes with the most anticipated new feature: defensive weapons. Thanks to @Pecus we have 5 completely new weapons and a more reasonably working parachute. The stub of the instruction manual describing these weapons is available here: https://github.com/pkali/scorch_src/wiki/Instruction-manual.
+
+The new inventory system has been added. Call it by pressing the "I" key or short-pressing fire. Select the weapon to use by moving the joystick or cursor keys right. Switch between offensive and defensive weapons by moving the joystick left. Fire/escape to quit inventory.
+
+Another significant playability change is #54 - it is not finished yet, but keeping the joystick up or down makes force increase/decrease faster. Also - short press of fire calls Inventory, long press fires the shell. The timings are experimental, please let me know if this needs a modification/improvement.
+
+Tickets closed:
+* https://github.com/pkali/scorch_src/issues/92 - less unnecessary cleaning of the offensive texts
+* https://github.com/pkali/scorch_src/issues/89 - improved collisions with tank
+* https://github.com/pkali/scorch_src/issues/71 - ditto
+* https://github.com/pkali/scorch_src/issues/11, https://github.com/pkali/scorch_src/issues/26, https://github.com/pkali/scorch_src/issues/8, https://github.com/pkali/scorch_src/issues/20 - new inventory system
+
+###### Build 143
+2022-06-05
+Rewrite build. We redone several important parts of the game to allow for bug fixes and requested features. Generally it was a great success, but some new bugs appeared. This build is nice for the eye, but beware, no mercy for testers again :)
+Only visible changes listed, because you are possibly not as excited as we are for the new Flight routine and ground collisions by @Pecusx.
+- https://github.com/pkali/scorch_src/issues/84, https://github.com/pkali/scorch_src/issues/63 - tanks now say good bye properly!
+- https://github.com/pkali/scorch_src/issues/74 - Press [ESC] to quit the game at any point, with a confirmation when the round has already started. Please note the keyboard is not checked all the time, so press it for a while, especially when AI tanks are ru(i/n)ning the show.
+- https://github.com/pkali/scorch_src/issues/56 - there should be no occurrences of frivolous weapon purchases. Please report all tanks getting their munitions from uncertified sources!
+- https://github.com/pkali/scorch_src/issues/47 - It seems that the bad sequence of turns has been ameliorated. Fix is trivial, finding the culprit - far from it. Please pay special attention to fairness of shooting in case the fix is still longing for the fjords.
+- ATTRACT mode works how it should - screensaver saves screen only when HUMAN should input something.
+
+###### Build 142
+2022-05-30
+Late build. The bugs we tried to squelch turned out to be more difficult than usual. Some progress has been made though even if it is not yet visible.
+- 4x4 font rewritten by @Pecusx as a prep for Y standarization. It makes the messages to appear faster. This is a good change.
+- https://github.com/pkali/scorch_src/issues/5 and #80 fixed (again) - no funkybomb traces staying on the screen
+- https://github.com/pkali/scorch_src/issues/70 too strong Shooters fixed
+- https://github.com/pkali/scorch_src/issues/63 - tank say goodbye when (mostly) visible
+- several other small changes and improvements that will pay off in the following releases.
+
 ###### Build 141
 2022-05-22
 Debug build. Thanks to all testers for finding numerous bugs. We tried to fix some of them and we have introduced some new for your enjoyment.
-- #73 Fast forward. Press [START] to speed up the game where it can be sped up. Not in many places, mind you.
-- #72 Screen glitches improved
-- #70 AI shoot with more force than their energy allows. We might still have to revise this one
-- #69 Explosions wrapping around the screen
-- #67 Screen glitches after intro
-- #65 Saved ~90 bytes by removing cosinus table
-- #62 Empty list of defensive weapons gets corrupted. Plunged it with a new defensive weapon - "White Flag". Honor of the tank crew prohibits them from buying it (yet)
-- #61 [SHIFT] was repeating the last key
-- #57 Fire too sensitive on a real machine. Switched to shadow registers. First recorded use of Atari OS :O
-- #55 Glitches in the status bar. This one was surprisingly tough.

-TODO and BUGS file
-
----------------------------------------------------------
-Known bugs (+ means bug is fixed)
-004. when parachute is on and the tank dies (e.g. hit by a powerful
-     weapon) the dead (invisible) tank falls on parachute
-     (and uses one parachute more than necessary)
-005. tank stands still on a one pixel spike - it should fall
-     (possibly all that is necessary is adjust of WhereToSlideTable)
-017: Observed MIRV loops - it shoots and shoots MIRV all over the screen. Very rare.
-020: sometimes leftmost or rightmost remains of the funkybomb smoke do not get cleared
-     I think it happens when one of the bombs goes out of the screen
-023: NEW BUG. After the last change (bug 007) now the last shell of any weapon gets removed and 
-     the game switches to Baby missile.
-
-Fixed:
-+001. when bullet goes straight down very fast it misses the tank
-     it happens only when tank is standing on the bottom of
-     the screen (no ground below)
-+002. points after the round are not calculated correctly
-+003. if death's head explodes low, the lowest explosion wraps
-     and appears on the top of the screen
-+006. After some attacks (like MIRV and leapfrog the OffensiveText 
-     stays on the screen (and becomes a static decoration)
-     It possibly happens when a tank kills itself with mirv or leapfrog.
-+008. After a round the last tank sprite stays on the screen. 
-     This hurts only when the last tank is under the table with results!
-+010. Even MORONS shoot their feet too often - increase min. randomised energy.
-+011. High flying bullets sometimes cause brief screen garbage - like a DL damaged
-     for a fraction of a frame.
-     Update - these are NOT high flying bullets - it just happens during bullet flight
-+012. (newly introduced) Death explosions are offset right and possibly up.
-+013. sometimes demo mode does not work (it stops on results display)
-+014: FunkyBomb shoots with too high angle
-+015: Only first shoot of FunkyBomb is correct (with smoke and fast), 
-     the next are like missiles
-+016: Additional explosions after Frogger do not have falling soil (?)
--018: MINOR: ydraw, yhit, ybyte variable is sometimes treated as WORD, sometimes as BYTE. 
-     Making it consistent would save both time and space (not much)
-     REJECTED: too much work - different routines depend on checking high byte. 
-+019: AI menu does not recognize keyboard up (prints "-" in tank name)
-+021: check MWA, ADW, SBW macros - bad modifications of bytes found!!!
-+009. When result in points is >99 then only 2 first digits are displayed
--022: shooting funkybomb decreases number of bombs too much! (2 instead of 1?)
-+007. Decreasing of number of bullets after a shoot does not work correctly
-     (e.g. 2 bullets are deducted instead of 1) FUNKYBOMB!!!
-     it looks like it is fixed, although what I did was moving decreasing before jsr shoot
-+000, Game crashes from time to time, code and/or screen gets corrupted
-
-
----------------------------------------------------------
-To do
-*004. The game has no end!!! Add ending!!!
-     A good idea for an ending - a TIP pic - Red Army taking Berlin :)
-	 Another - vector tanks like in BattleZone
-	 Another - stickman tankmen
-006. Add sound effects (maybe sampled? or mp0 (sound based on fft))
-007. There is no defensive weapon handling (only parachute works,
-     but also provisionally
-009. Make AI in the existing framework (ongoing)
-010. It is impossible to look up a number of parachutes left.
-018. Speed up soil down after soil eating weapons - correctly calculate 
-     ranges as now range is very broad even when very little soil is eaten.
-019. Purchase impossible with joystick only. Add buy on e.g. joystick right.
-020. Not a bug per se, but ydraw variable is word, possibly it can be switched to byte
-021. Add player colors to purchase screen
-022. Make colors more contrasting
-024. no visual indication of using defensive weapons
-
-Done:
-
-+001. Start each round with a)worst tank or b)random tank
-      (Worst tank starts first)
-+002. Start each round with random angles (not always 45 degrees left)
-+003. Add colour of the given tank to the screen
-     E.g. when a given tank is shooting it's colour could be behind
-     tank name on the text screen
-+005. Add number of rounds to the options menu
-+008. No computer operated opponents - make a framework for AI!!!
-+011. Colouring the top status lines in a colour of the active tank.
-+014. Demo mode - when all tanks are CPUs let them play non-stop!
-     (replace waiting for a key-press after a round with a small delay)
-+015. Switch to mads for easier development (mads speeds it up, no doubt)
-+016. Speed up death's head (e.g.: draw each second circle)
--017. Wide screen mode (with scroll?)
-+012. Decreased number of bullets should be displayed just after the shoot.
-+013. Check LineTable - possibly it is unnecessarily long. Checked. It is OK
-+023. Make not implemented weapons raise NotImplementedError :] Done by making it impossible to purchase free weapons (price == $0)
