 * **Auto Defense** - activates the mode of automatic activation of defensive weapons. After its activation, the tank automatically activates the strongest shield it has (consuming it, of course) at any time when there is no shield (also between shots of other players). At the same time, if the tank's energy level drops below 30 units, it automatically activates **Battery** if it has it. This weapon remains active until the end of the round and is indicated by the "computer" symbol before the name of the active defensive weapon in the status line. It is the second defensive weapon that does not deactivate other defensive weapons when used.
 * **Spy Hard** - Help for the forgetful :) . When activated, it shows a preview of information about the next opponents one by one. Left/Right - changes the "spied" tank. Fire/Space/Return/Esc - ends the "spying". This is the last defensive weapon, which does not deactivate other defensive weapons when used.
 
+Due to the different warhead tracking system of **MIRV** weapons, the **Bouncy Castle** and **Mag Deflector** defensive weapons only use the shielding function when hit by these weapons. In addition, **MIRV** warheads do not bounce or fly through sidewalls when falling!
+
 None of the shields protect against **Napalm**. **Bouncy Castle** or **Mag Deflector** on a direct hit will deflect it or carry it past, but just hit very close to a tank and its shield will not save it.
 
 **White Flag**, **Hovercraft** and **Nuclear Winter** weapons, when selected, require activation, this is accomplished by "firing a shot" after the selection of that weapon. Of course, the shot of the offensive weapon is then not fired, but only the selected defensive weapon is activated.

 ## Changelog:
 
+###### Version 1.26
+2023-01-23
+
+Early morning edition. It is 5:11 am and I am writing this instead of dreaming of electric sheep.
+For the last 6 weeks theversions we released had an awful bug - the conversations of tanks were completely invisible. Thanks for pointing this out, RB5200.
+- tanks talk to each other again
+- better stochastic non blocking wait one frame
+- rare dstance measurement bug fixed (rarely a tank survived a direct hit)
+- 5200: second fire works (by RB5200)
+- "visual debug" mode in A800 version, triggered by pressing [CTRL]+[HELP]. It displays distances measured, laser aiming and aiming technique. It leaves a mess on screen, but it does not impair the game, just makes it a bit harder.
+
+
+###### Version 1.25
+2023-01-17
+
+Y2K Compliance Edition
+This version is 5200 SuperSystem focused.
+- the correct production year in the splash screens!!!
+- very rare hangups when accessing the inventory seemingly eliminated, thanks @RB5200 for testing!
+- a new feature - pressing [Tab] (atari800) or [5] (5200) when selecting the wind power switches wind mode to changing with each turn, which makes aiming arguably more challenging! It is indicated by "?" next to the "Wind" in the main menu.
+- pressing [G] during the game changes the color scheme (classic, Polish rainbow, Xmas).
+- all these changes were made possible thanks to the extensive code size optimization by @Pecus
+
+
+###### Version 1.23
+2023-01-01
+
+New year edition! Who could imagine?
+The new feature is that pressing [Tab] in the main menu now changes colors of the small tank area down the screen and makes it clear what color version you are going to run (classic/ Polish rainbow/ Christmas colors).
+Also a small gradient optimization. 
+
+
