Here is Chronos 1.4 Software V0.3.2-RC2. Do not use this software version if you are capturing something that is not easily replicated.

Notable Changes:
 - Automatic ADC calibration during black calibration, which should reduce column banding across a wider temperature range.
 - Add a storage tab to the util menu to view, eject and format the attached storage devices.
 - Speed boost at most resolutions, with a top speed of 1069fps at 1280x1024, and 40420fps at 320x96.
 - Configurable automated power-on and off depending on the AC adaptor status.
 - Option to disable the ring buffer when in segmented recording mode.

 - Factory black calibration is now user accessible from the Factory tab of the util window.
 - The software update button has been moved to the storage tab of the util window.
 - Shipping mode to disable power-on by battery until an AC adaptor is attached.
 - Add a watchdog to reboot the camera in case of a power-on boot failure.
 - Display descriptive error strings instead of number on failure.
Minutiae (relative to RC1):
 - End of recording from lack of free space generates a warning dialog.
 - Revert to a valid resolution when focus is lost while editing the H/V resolution widgets.

Fixed Bugs:
 - Gated burst record mode may lock up after several trigger edges.
 - Gated burst record mode unreliable when trigger debounce is enabled
 - Memory leak in the M3 video coprocessors which could lead to a crash after lots of H.264 encoding.
 - Ignore video which was recorded during zero-time black calibration (which happens after changing resolution).
 - Stuttering issue on the playback window on new production LCD modules.
 - Fixed deadlock in camera when restoring user settings from external media.

Fixed Bugs (relative to RC1):
 - Corrupted overlay text at narrow resolutions.
 - Video stream would remain in playback when starting recording via auto-record.
 - Opening and closing the white balance menu can lead to an unexpected change of the custom preset.
 - Bug in calculating the trigger delay on boot (segmented mode only).
 - Ensure a minimum of 0.25 bits/pixel when encoding h.264 video.
 - Crash can occur when saving extremely short videos.
 - Lag when focus peaking or zebra stripes (focus and exposure aids) are enabled
 - On the save file settings window, the bitrate as listed above the resolution may be lower than the actual bitrate, if Saved File Framerate is lower than 60fps

Fixed since V0.3.2-beta-6:
 - Changes to focus aid or exposure aid (zebra stripes) would have no effect until resolution is changed.
 - Changes to exposure may be overwritten during black calibration.
 - Bad image quality at 336x120 resolution
 - Util window, storage tab - bottom of text cut off if device has multiple partitions
 - Factory black cal (black cal all resolutions) would get overridden by old user black cal, if a user had done their own black cal, even before.

Known bugs still in V0.3.2-RC2:
 - Video system may crash after about 200-300 saves, on average. (bug present in RC1 and RC2)

Updating Your Camera
 - Extract the `.zip` file into the root directory of a FAT32 formatted USB drive.
 - Turn on your camera and insert the USB drive into the USB/eSATA combo port, not the one labeled 'OTG'.
 - From the main window, tap the `Util` button to open the utility window.
 - As a precaution, tap the `Backup Calibration Data` button on the utility window before starting the update.
    - When the backup is completed, a pop-up window will be displayed.
    - Tap the `Done` button to close the pop-up window.
 - From the utility window, tap the `Apply Software Update` button to begin the software update.
    - A warning message will be displayed, tap the `Yes` button to confirm and begin the update.
    - If a pop-up that says 'No software update found' is displayed, even when a USB stick containing the update in the correct location is connected, reboot the camera and try again.
 - During the update, the screen will go blank and an `Applying Update` message will be displayed.
 - After approximately 60 seconds, the update will be complete and the camera will restart.

Great News!

Do we have to factory calibrate after applying this update or just use it as is?  Will test this weekend. Thank you!

No, it's not necessary to factory calibrate after the update.  That feature really just does black cal for all of the standard resolutions.

Ok did some testing...

Everything works as expected with what seems improved column noise pattern reduction after calibration. It still requires camera warming up to get to a point where the calibration works pretty well, that is about 26 minutes warm up.
Fan goes faster when using AC power vs the battery, that is to be expected.

1 Bug Found: when using HDMI monitoring, you activate the focus asist function (peaking) on the camera and it slows to a crawl then image locks up and no motion is attained. Only fix is unplug the HDMI cable and things return to normal.  Camera refreshes signal and regular operation resumes.

It seems the cpu is overwhelmed when peaking is activated and HDMI is operating. Tried with a field monitor and an LCD viewfinder both showed the same problem,

Great job on the nice features like improved fps and storage info + format options, much appreciated!  :D

Hi all
I upgraded to this latest release as well and have experienced the same freezing/lack of response issue. In my case though I was messing around with a new lens which was heavy. I did not have an external monitor connected however the screen was rubbing against me as I messed around with the back focus adjustment. I didn't spot a pattern to it but it was doing it regularly. I tried one short recording whilst it was stuttering and that seemed to record ok. I have gone back to the beta in the mean time.
