 ## Changelog:
 
+###### Version 1.27
+2023-02-07
+
+Late evening edition. It is 2:11 am and I am writing this instead of dreaming of electric sheep.
+Our Senior Executive Art Director @+Adam+ ordered us to stop procrastinating and finally release the version with colorized mountains. So here it is. Enjoy :)
+Please note you can still press [Tab] or [5] in the main menu and revert to the classic or classy look of the "Polish rainbow" (it's a reference to a strangely accurate Wulffmorgenthaler comic strip: https://i.imgur.com/HMctP.jpg)
+Other changes:
+- nicer Lazy targeting and "visual Debug" for Lazy Boys
+- extreme memory optimizations to fit 2 new texts from @RB5200 based on "Sandford and Son"
+- fix for [G] key bug when turn wind changes were selected
+- fix for Lazy Boys deactivation bug
+- PAL mode now has got the full-color table, so it is possible to adjust colors better
+- the x-position of tanks was always adjusted to even X values, this is no more, which saves some hassle and unnecessary tank shakes left and right. As tanks are painted with sprites of a lower resolution, a rare artifact might appear here and there.
+- improved tank shapes
+
+###### 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, the versions 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 distance measurement bug fixed (rarely a tank survived a direct hit)
+- 5200: second fire (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 the screen, but it does not impair the game, just makes it a bit harder.
+

 ###### Version 1.25
 2023-01-17
 
@@ -58,8 +85,9 @@ 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, what makes aiming arguably more challenging! It is indicated by "?" next to the "Wind" in the main menu.
-- all these changes were made possible because of the extensive code size optimization by @Pecus

 ###### Version 1.23
@@ -658,4 +686,5 @@ For the first time Scorched Earth for Atari XL/XE (build 103) published.
 Together with Pecus we were working on this piece of code for four years and it does not look like it is accelerating so we decided to publish what we have. Last few weeks I was translating source code comments and labels to English to let other people work on this project with us. In other words Scorched Earth becomes an open source project :)
 Now it's your turn to help this idea happen!
