This is the first 64 bit version of B4A IDE, which means that it will handle better large projects.
It will be installed by default under Program Files\Anywhere Software\B4A.
It will not run on 32 bit Windows. Note that the CPU architecture doesn't affect the compiled apps.
RUNTIME conditional symbol - an automatic symbol that is added during compilation. It can be used to exclude code from the IDE case-corrector.
New DesignerUtils (DDD) library with a new designer script framework.
Bug fixes and other minor improvements.
Note that the UI Cloud has been removed. It was in quite a bad state for a while. Newer devices misbehave when running for a long time as servers and it became impossible to maintain it.
