Please lets wait for LVGL 9.2.1 release, we have patches ready to get
in sync, this is quite important and demanded feature to land in a
release, and I am sure this will attract new users/developers to the
NuttX community because this will be also announced to the broad LVGL
community :-)

Also we should fix ESP32 bootloader / esptool building unusable
firmware image, this platform is too popular to have this kind of
problem.

If anyone has a free moment to verify in depth the memory leak that
would be also very good to know why that happens - is it ostest
problem or nsh / os problem coming from recent updates?

I know Alin the release process is time consuming and cost you lots of
effort, and additional problems cost you additional work time, we all
much appreciate that!! <3 :-)

Release quality is far more important than quantity, its not only
about bumping numbers. I know from other projects that rushing the
release with known problems behind may be strongly discouraging and
pushes people away from a project. We all want to create a reliable
solution that works out of the box with no surprises right? :-)

Have a good day folks :-)
Tomek
