Today we have release v4.1.2 of lux.js, immediately followed by v4.1.3. These updates are intended to reduce beacon payload sizes for a small number of RUM customers.
Improvements
- Added
LUX.maxAttributionEntriesto control how many attribution entries are sent in the beacon. The default value has been reduced from 50 to 25 to reduce payload size. - Long animation frame attribution is sorted by total duration, so the slowest scripts are prioritised in the payload.
- Minification optimizations have reduced the output size.
Other
- Invoker and source function name have been removed from LoAF entries to reduce payload size.
