Updates since last Meeting:

2020AUG + 2020OCT Release
ACS Python 3 Porting
- Python 3 made official in 2020AUG
ACS Changes
- Compatibility and new capabilities for the new Makefile being developed
- Increased speed of ACS initialization script helper
- Thread-safe improvements
- ACS now compatible with gcc 8.3.1 and C++14, C++17 and C++2a (Draft of C++20 as of gcc version 8.3.1 20191121)
- Components de/re-activation improvements
- Obsolescence Management Roadmap
  - Boost (1.66.0) + Xerces-c (3.2.2)
  - Corrected Python package version (Open version, duplicates w/different versions, etc.)
  - Java Dependencies now installed with Maven as part of ExtProds
- Code to allow random delay when starting monitoring in a component to prevent too much simultaneous hardware demand from components sharing hardware resources (Network, CAN channel, etc.)
- Python imports no longer require ACS to be running. The code that was implemented in this way, was changed to be used as a singleton instead
- ComponentCaller now supports simple asynchronous calls that depend on basic callbacks (CBvoid, CBfloat, ...)
  - Future releases will increase the functionality to support custom callbacks
- Improvements to properly support Octet sequence in Python simulator and objexp (Problems seen in ACS workshop!)
CentOS / RHEL 8
- ACS compatibility finished and test cases working normally
Monotonic Clock tests done
