Version 2.8.0¶
New minor release, created on 29th January 2021. Milestone: v2.8.0 release
Compatibility with respect to last release (v2.7.9) : API compatible, but ABI incompatible
Backward incompatible changes
We dropped support for SLC6 in this release (since support for the OS itself ceased in 2020).
Since uHAL and the ControlHub are often not used on the same machine in larger systems, we split up the previous YUM group (
ipbus-sw) into three groups:uhal,uhal-debugandcontrolhubSince the YUM repositories now provide Python bindings RPMs for multiple Python versions, we updated the name of the Python bindnings and GUI RPMs to
cactuscore-uhal-pythonXYandcactuscore-uhal-pythonXY-gui(whereXandYare the major and minor Python version numbers).
Major improvements
uHAL: Added Python bindings for newer Python versions to official YUM repositories - specifically for Python 3.4 and 3.6 in CentOS7, and for Python 3.6 and 3.8 in CentOS8 [issues #227 and #235]
Note: Python bindings are now created using a header-only library (rather than boost Python), which allows for more flexibility in building the bindings for different Python versions on other operating systems as well (since boost does not need to be built against the same Python version).
uHAL: Updated source code to use C++11 features and libraries [issue #226]
Minor improvements
uHAL: Added optional
max_payload_sizeattribute toipbusudp,ipbustcpand chtcp` URIs, to enable full use of jumbo Ethernet frames [issue #221]uHAL: Updated code to eliminate warnings encountered when building with stricter (non-default) compiler flags [issue #232]
