Change Log for Releases
=======================
## 21.04
* Rename project from srsLTE to srsRAN
* Add initial 5G NSA support to srsUE (including x86-optimized FEC and PHY layer)
* Add PDCP discard support
* Add UL power control, measurement gaps and a new proportional fair scheduler to srsENB
* Extend GTP-U tunneling to support tunnel forwarding over S1
* Optimize many data structures, remove dynamic memory allocations in data plane
* Improved S1AP error handling and enhanced event reporting
* Update ASN.1 packing/unpacking, RRC to Rel 15.11, S1AP to Rel 16.1
* Update PCAP writer to use UDP framing
* Other bug-fixes and improved stability and performance in all parts
## 20.10.1
* Fix bug in srsENB that effectively disabled UL HARQ

See the srsRAN project pages (www.srsran.com) for documentation, guides and project news.
It includes:
* srsUE - a complete SDR LTE UE application featuring all layers from PHY to IP
* srsUE - a complete SDR 4G/5G UE application featuring all layers from PHY to IP
* srsENB - a complete SDR LTE eNodeB application
* srsEPC - a light-weight LTE core network implementation with MME, HSS and S/P-GW
* a highly modular set of common libraries for PHY, MAC, RLC, PDCP, RRC, NAS, S1AP and GW layers.
