"CV distance tolerance" and "stop CV on angles >" parameters are missing from mach4

Mach 4 is missing "A-rotations enabled" so that rotary toolpaths can be properly backplot in the toolpath viewer.

version 034 has corrected the feed issue. Thank you very much.
My motor max velocity is 850.2mm/min (for some reason the 0.2 gets added when i enter 850.
The machine now jogs and accelerates properly at 849.9mm/min.
Close enough for me. Thanks.

Immediately no, but I don't want to see the bug persist into future versions as I'd like to be able to install newer releases and enjoy the feature additions and bug fixes.
It's odd that I'm the only person experiencing this when I have had it working fine since  early Mach3 1.x versions and now it changes in v0.030.

My spindle is controlled by a potentiometer on the spindle controller not through Mach, so I can not verify that issue.

AMD Athlon 2000+/2100+
FSB 133
1.0GB RAM

The machine is traveling at a faster velocity, I can see and hear it, and the DRO is reading faster.

Some change the occurred in 0.30 caused this.

I downloaded and test all versions of Mach between 0.20 and 0.33 excluding 0.32 as I didn't see it on the server.
The velocity calculation changed began significantly overfeeding in version 0.30. With motor velocity max set to 850mm/min the machine jogs at 1115mm/min. Please look into this. I can reproduce this on 2 machines.

No. I have a 4 axis mill and controller that has gecko 201 drives, charge pump, 3 home switches and a probe, nema23 250oz-in 0.9deg steppers, and a couple 110VAC relays and my computer is more than ample to run mach, using XP pro. I've been through many versions of mach over the past 4 years and all have worked fine for the most part.

 I went back to ver 0.020 and velocity behavior goes back to normal. Tried version 0.033 again after that and overfeed happens so there is definitely a software issue. I do use my own screen set, I'm going to try to use the default install, screen, and xml to see if maybe something from my screen set iis causing this. I have 2 machines so I will also try this on my other machine.

I compensated the motor tuning to get it to run closer to my desired max velocity, but this is a workaround not a fix.

Didn't change any of my settings. Copied myscreen.set, machlic.dat, mach3_4axis.xml, my macro folder, my image folder, my machmill shortcut that loads my profile. Uninstalled mach3 0.020, deleted c:\mach3r, installed mach 0.033, rebooted, copied my files back, started mach.

I've done this 2x now and both times mach overfeeds velocity by about 25% on all jog and feed moves.

Attached is my .xml

Velocity definitely and possibly acceleration too but its hard to perceive if its over accelerating.

Simple test.
My motor tuning is set to 1000mm/min for X.
Jog X and the velocity reaches approx 1250mm/min. It shouldn't go over 1000mm/min and doesn't in older Mach versions such as 0.020.
I upgraded from 0.020 to 0.033 so I don't know what version this bug as introduced.
