It was written shortly after the BCD was invented with Vista, and the MS supplied utility proved so inadequate (and difficult to use).
It obviously changed rapidly early on, as bugs and wrinkles were sorted, then developments in other Neosmart software were incorporated to turn it from a simple shell for BCDedit in version 1, to a largely automated version 2.
Beta testing of that version generated multiple builds to handle the complexities of multiple user configuration/hw possibilities which it gradually encountered with increasing use, but it progressively became more stable, whilst the BCD became the MS booting standard all the way through to W10, essentially unchanged since Vista.
Only the gradual spread of UEFI replacing the old IBM PC MBR/BIOS standard has thrown a spanner into the works, but since MS has opted to prohibit many boot options under UEFI, EasyBCD has, if anything, had even less to do and become even more stable.
I can't recall anyone reporting a (genuine) bug in the code for a very long time, and the "ideas and wishes" forum is not exactly buzzing with activity, so until MS takes a major sidestep in the way it boots a future OS, I don't anticipate a lot of activity in the Beta testing thread any time soon.
