When is the July 2019 Subpixel Linearity Improvement coming?

  The Chief Technical Officer of the RealSense Group at Intel (agrunnet) mentioned it yesterday (5 Aug 2019) in the present tense, though it could have been a reference to a firmware that is in internal testing rather than publicly available.

  At the time of writing this, the latest recommended firmware is version 5.11.6.250.  It looks as though the changes may have been added in SDK 2.23.0 on June 10.

  

  There is not currently listed a firmware version 5.11.9 or newer listed for public access on the firmware download page.  It was mentioned 3 weeks ago by an Intel support team member that a 5.11.12 firmware with an auto-exposure bug fix was in the pipeline, so the sub-pixel linearity support may be part of the next firmware.  I do not have any information on when it will be released though.

  Thanks Marty, I didn't see that in the release notes.

  The link mentions the C/C++ API, do you have the Python equivalent?

  The firmwares have their own release notes document, separate from the SDK and API release notes.  

  I could not find any reference to the new instructions outside of the subpixel linearity document.  One of the Intel staff on this forum or the RealSense GitHub site should be able to provide advice on this issue (I am not an Intel employee, so do not have access to information about a Python equivalent for these functions).
