 ## Changes:
 
-###### Build 138
+###### Build 144
+2022-06-19
+Juneteenth release is coming with the most anticipated new feature: defensive weapons. Thanks to @Pecusx we have 5 completely new weapons and more reasonably working parachute. The stub of 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 "I" key or short-pressing fire. Select weapon to use by moving joystick or cursor keys right. Switch between offensive and deffensive weapons by moving joystick left. Fire/escape to quit inventory.
+
+Other significant playability change is https://github.com/pkali/scorch_src/issues/54 - it is not finished yet, but keeping joystick up or down makes force to increase / decrease faster.
+Also - short press of fire calls Inventory, long press fires the shell. The timings are experimental, please let me know it 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.
+- https://github.com/pkali/scorch_src/issues/73 Fast forward. Press [START] to speed up the game where it can be sped up. Not in many places, mind you.
+- https://github.com/pkali/scorch_src/issues/72 Screen glitches improved
+- https://github.com/pkali/scorch_src/issues/70 AI shoot with more force than their energy allows. We might still have to revise this one
+- https://github.com/pkali/scorch_src/issues/69 Explosions wrapping around the screen
+- https://github.com/pkali/scorch_src/issues/67 Screen glitches after intro
+- https://github.com/pkali/scorch_src/issues/65 Saved ~90 bytes by removing cosinus table
+- https://github.com/pkali/scorch_src/issues/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)
+- https://github.com/pkali/scorch_src/issues/61 [SHIFT] was repeating the last key
+- https://github.com/pkali/scorch_src/issues/57 Fire too sensitive on a real machine. Switched to shadow registers. First recorded use of Atari OS :O
+- https://github.com/pkali/scorch_src/issues/55 Glitches in the status bar. This one was surprisingly tough.
+
+###### Build 140
+2022-05-15
+Huge internal changes by @Pecusx. The whole game screen has been inverted - ground is now background color, "sky" and empty areas are in fact pixels. This allowed for introducing better tank colorization, fully devised and lead by Adam. The process started and results are already promising - the colors of tanks and the status bar are closer. We might get even better ones in the next builds.
+- few new sfx added (end of round, weapon change, soil eating weapons)
+- added colors to tank name and level selection screen
+- Bug https://github.com/pkali/scorch_src/issues/57 possibly alleviated by using TRIG0S instead of TRIG0. Please test - it did not show for me.
+Other unlisted minor bugs and typos fixed.
+"Nightly" version moved to `develop` branch. `master` will be updated with stablish and playablish builds only.

----------------------------------------------------------
-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)
