#8 | 26129 | Paul Allen | Move p4python to Main branch | ||
#7 | 23584 | Sven Erik Knop | Updated P4Python to 2017.2 in sync with the internal development version. | ||
#6 | 22483 | Sven Erik Knop | Updated to 2017.1 | ||
#5 | 21667 | Sven Erik Knop |
Update OpenSource version of P4Python to 2016.2 This source drop is virtually identical to the internal release. The source is also available from pypi as a tar ball, here for completeness and to encourage anyone who wants to extend or fix P4Python. |

#4 | 20225 | Sven Erik Knop | Updated P4Python to released version of 2016.1 | ||
#3 | 16835 | Sven Erik Knop |
Updated P4Python to the 2015.2 release. This update contains a lot of whitespace changes as well to get the internal and public codebase in line. New features include: Updated spec map to match 2015.2 server Native C++ interface for P4.clone and P4.init. This change requires P4API 2015.2 Minor signature changes to add kargs for every command |
