Hi,

It's been a while since I gave you an update on Ostinato.

We've been working hard for the upcoming 2.0 release later this year!

Here's a sneak preview.

✨ New Features

Port/Stream Configuration

Save port configuration to file - includes port settings, devices and streams
Vary packet fields every 'n' packets (instead of every packet)
ARP/NDP Resolve is faster for scaled streams
Delete streams is now blazingly fast!

UI/UX

Auto save sessions
Drag 'n drop stream, port and session files into the GUI
Auto expanding docks - utilize the full app window space
Monitor transmit duration in real-time and transmit for a fixed duration
Improved Stream Stats UI

Protocols

RARP
IGMP/MLD now automatically set the required IP header fields - DstIP, TTL, IP Options
Support for trailer protocols like PRP with custom user-scripts

PCAP

Reduce time taken to import large PCAP files
Fixes for PCAP import failures and diffs from original
Save as PCAP uses current time instead of epoch
Retain original PCAP timestamps for import-edit-export PCAP use case

Python API

Save as python now generates code to configure port settings, device groups in addition to streams
New convenience APIs: clearPort(), waitForTransmitFinish()

plus a bunch of bugfixes!

Checkout the changelog for the full list.

We've also spent some significant time improving our continuous build and testing infra so that we can make more frequent releases going forward.
