The direct download link should be here (this is the first time I am trying the direct download links from the google drive, I hope it will work).

Despite the fact that there is a minimal amount of changes in this beta 5, I still decided to upload it just because I did not refresh the software status for a looong time. What is new is that an expression cannot be touched (highlighted) any more by pointing the mouse pointer just above it (it can still be touched by pointing the mouse pointer just below it). Hopefully this will reduce touchiness of the user interface… Other than that, I just did some minimal optimizations and that’s all.
