General
NEW - Roxie compatibility check missing (Fixed in 5.4.6)
The code for checking whether a WU was compiled with too old a version of the compiler is missing in versions 5.2.0 – 5.4.4, though the check is still performed when loading the slave queries. If an incompatible workunit is loaded you may therefore see "Query suspended on slave" errors even though it appears to load successfully on the server. In more severe cases the server may crash when attempting to load the incompatible workunit on the server.
Any deployed workunit created with a compiler OLDER than 5.2.0 needs to be deleted before starting a 5.2.0 or later Roxie.

Support for VWware Player and server withdrawn after HPCC Systems 5.4.2
From HPCC Systems 5.4.4, VMware® Player or Server will no longer be supported due to licensing issues and users should migrate to Oracle VM VirtualBox® instead.

Upgrading from previous versions of HPCC Systems
The HPCC platform package naming convention was changed at version 5.2.0. This can cause issues with upgrade installs (e.g., rpm -Uvh or dpkg -i) by leaving multiple packages installed which can prevent the platform from functioning properly.
If you have an installed version prior to 5.2.0, you must uninstall before installing any version after 5.2.0.
For details about the name change, see:

HPCC Systems ECL Plugin for Eclipse requires authorization of the self signed certificate
This plugin does not automatically authenticate with self signed certificates, since doing this would circumvent obvious security safeguards. As with other self signed certificates, you must specifically authorise the certficate on your own computer. On installing the ECL Plugin for Eclipse, a Java error may be produced in the Server Version field when you get to the point when you are trying to establish a server connection:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Highlighting that you need to set up an exception.

hpccsystems-nagios monitoring package may require a force install on RPM based system
This issue is caused by the way CMake creates the package. For more information, see this ticket: https://public.kitware.com/Bug/view.php?id=13609
System monitoring icon does not respond when launching ECL Watch for the first time (Fixed in 5.4.4)
On launching ECL Watch for the first time, the Monitoring icon does not respond the first time it is clicked. Simply click a second time and the monitoring page will be displayed as requested. This was reported against HPCC Systems 5.4.0 but was resolved in version 5.4.4-1

Restart needed for ECL IDE after downloading GraphViewer in ECL Watch
When installing a clean version of the platform, you may find that graphs are not displaying in ECL IDE and you need to install the new Graph Viewer. To do this, go to ECL Watch and you will be prompted to confirm that you want to use the new Graph Viewer. After confirming in ECL Watch, restart the ECL IDE and your graphs will be displayed.
