This section describes how to update/upgrade DATAFLOW Runtime packages. Updates are received as new zip packages containing all of the required files. There are no patches or incremental updates that are provided.
Replace the current Imt.Base directory in your project with the version that should be used instead. The current version can be found in Imt.Base/Imt.Base.Core.Platform/version.h.
For binary releases, also replace all binary files (*.lib, *.a) with the files from the ZIP package of the correct version.
An update/upgrade of the DATAFLOW Runtime might cause the embedded software to behave differently and requires a re-evaluation of the system.
This can be automated when the DATAFLOW Frames Project generator module in DATAFLOW Designer is used. In that case, just select the new package version and generate code.
If only the third digit of the version number changes, for example from 22.214.171.124 to 126.96.36.199, the changes are only bugfixes and are backwards compatible. Always use the lasted bugfix release of your runtime version if available.
Consult the Release Notes  for a list of bugfixes.
If the second digit of the version number changes, for example from 188.8.131.52 to 184.108.40.206, the changes are backwards compatible feature changes. Minor changes to your project source code may be required.
It is also strongly recommended to perform a complete validation of your software after a minor update of the DATAFLOW Runtime.
Consult the Release Notes  for important changes between minor releases.
If the first digit of the version number changes, for example from 220.127.116.11 to 18.104.22.168, the changes are major breaking changes. These changes will require major changes to your project source code.
It is also mandatory to perform a complete validation of your software after a major update of the DATAFLOW Runtime.
Consult the Release Notes  for important changes between major releases.
