¶ Summary
The licensing toolkit has been extended to support flexible license distribution allowing for a more efficient use of licenses. The change applies to the use of floating licenses via a license server only. There are no functional changes in the use of node-bound licenses.
The licenses stored on a shared license store are dynamically re-distributed at runtime based on the actual usage. There is no need to pre-allocate a fixed number of licenses on initial loading of UniMRCP Server instances.
