 ### I can and will only support e-paper panels I have!
-- I can accept panel donations to add support to GxEPD2.
-- But only few panels at any time, and only panels from known sources. 
-- Adding support will take as much time as needed.
+- I accept panel donations to add support to GxEPD2 only on exception.
+- I support only panels from known sources that are well documented.
+- Let me know about interesting panels that fall into this category.
+- I occasionally buy new panels, but adding support will take as much time as needed.
 
-### Version 1.6.2
+### Version 1.6.3
+- updated GxEPD2_4C.h with WIDTH_VISIBLE (for GDEY0213F51)
+- updated GxEPD2_154_Z90c.cpp powerOff() handling
+- updated powerOff() handling for other 3-color displays
+#### Version 1.6.2
 - fixed support for GDEY029T71H 2.9" b/w 168x384, SSD1685
 - GxEPD2_WiFi_Example: added direct (non-buffered) BMP download to 7-color displays
 - some minor fixes
