AXIS 8.1

Overview
This release is focused on minor enhancements to the EPG and Live playback APIs in order to support new linear features in the next major releases of the reference apps. It also includes various improvements to monitoring, performance, security or general usability of both AXIS API and Presentation Manager.  
It is a recommended upgrade for all customers on 8.x.
What's New
Enhanced EPG APIs
The API used by apps to load programme schedules was extended with an additional parameter to limit the amount of data returned not only by date, but also by count. Moreover, a brand new API endpoint was introduced to support loading detailed information about a particular schedule entry.
Improved data model for live playback 
Live Channel assets used a simplified media file tracking data model that was insufficient to support live playback in different types of devices. This has been updated to use the richer media file data model of other playable asset types like movies, programs and similar.
Enhanced APM support  
One of key AXIS Platform API components (ISL) was updated to support more granular transaction monitoring in New Relic, making it easier to identify bottlenecks or areas of user experience that may become sub-optimal during traffic spikes.
In a future release we will be migrating to DataDog as the default APM solution for the entire AXIS platform.
