System Information
Operating system and graphics card

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)
Worked: (optional)

Short description of error

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

BoolTool 0.2 and BoolTool 0.3.5 is nothing wrong.
Focus solve problem on Blender 2.77a is fine.
Blender 2.78 and Blender 2.78a problem on BoolTool.
Please fix come from 2.77a to 2.78xx and BoolTool 0.3.5 is fine.

I has been test on Blender 2.77a within BoolTool 0.3.5 is fine.
I has been test on Blender 2.78 within BoolTool 0.3.5 is problem.

Please follow our submission template and guidelines and make a complete, valid bug report, with required info, precise description of the issue, precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.
Videos and/or links to external sites etc. are not acceptable as bug report (they can be provided as additional information only).

Also, differences between both solvers are known and expected, especially in limit cases (coplanar faces etc.), where there is no real “good” solution. BoolTool should probably just update its code to keep using Carver solver if it wants to keep exact same behavior as in previous versions.

Like it was said, this is currently a limitation of the BMesh Boolean solver (library) and not the add-on itself.

The solver produces different results in certain cases compared to Carve (which was the only one available in previous releases). Furthermore, either or both of them can produce unsatisfactory results.
That's the reason for having the option for choosing it in the Booltool Add-on preferences. Gives users more options for handling different cases.

To make things a bit more clear, I've updated the Booltool Wiki page with a small explanation about the rationale for having both options available.
https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Object/BoolTool

@Kent-Davis to have Booltool behave like in the previous releases, set the Boolean Solver option to Carve in the add-on preferences and Save User Settings.

Developer info:

For the future developer reference about this specific limitation of BMesh Solver, I'll post the image comparison here:

To check some of the current problems look at the parent task blender/blender#47030 or Modifiers tag.
