Release 4.8.0

[4.8.0] - November 29, 2021

New Features

• Added a Lite bundle which does not include Data file manager and Event Processor packages. This reduces the bundle size up to 20% and is helpful for some platforms (such as edge service providers) that do not need extended functionality offered by these packages.
• Removed Client engine validation in the SDK to allow tracking events from new clients without modifying SDK code.

Performance Improvements

• Reduced SDK client initialization time by removing OptimizelyConfig creation from initialization. The OptimizelyConfig object is now created on the first call to getOptimizelyConfig API.
• Made Improvements to logging mechanism. The SDK no longer concatenates and formats messages which do not qualify for the log level set by the user.

Changed

• Updated json-schema package version to 0.4.0 to fix a high-severity vulnerability (Prototype Pollution).
