# RELEASE NOTES: # ## [v1.2.1](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.2.1) -> February 2020. ## * Bug fix for mutex lock for wake-up signal ## [v1.2.0](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.2.0) -> January 2020. ## This version adds the following implemented features: * LTE-M : eNB support for Mode A repetitions - PUSCH CE - 8 Repetitions * Improved CDRX implementation for monolithic eNB * Experimental eMBMS support (now also on eNB side) * Experimental MCE - Multicast Coordination Entity * Bug fixes This version also has an improved code quality: * Better Test Coverage in Continuous Integration: - Initial framework to do long-run testing at R2LAB ## [v1.1.1](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.1.1) -> November 2019. ## - Bug fix in the TDD Fair Round-Robin scheduler ## [v1.1.0](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.1.0) -> July 2019. ## This version adds the following implemented features: * Experimental support of LTE-M - Single LTE-M UE attachment, legacy-LTE UE attachment is disabled * X2 interface and handover (also X2-U interface) - In FDD and TDD * CU/DU split (F1 interface) - Tested only in FDD * CDRX - Tested only in FDD * Experimental eMBMS support (only on UE side) * Experimental multi-RRU support - Tested only in TDD This version has an improved code quality: * Simplification of the Build System - A single build includes all full-stack simulators, S1/noS1 modes and one HW platform (such as USRP, BladeRF, ...) * TUN interface is now used as default for the data plane - for UE, eNB-noS1 and UE-noS1 * Code Cleanup * Better Static Code Analysis: - Limited number of errors in cppcheck - Important Decrease on high Impact errors in CoverityScan * Better Test Coverage in Continuous Integration: - TM2, CDRX, IF4.5, F1 - OAI UE is tested in S1 and noS1 modes with USRP board - Multi-RRU TDD mode - X2 Handover in FDD mode ## [v1.0.3](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.0.3) -> June 2019. ## - Bug fix for LimeSuite v19.04.0 API ## [v1.0.2](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.0.2) -> February 2019. ## - Full OAI support for 3.13.1 UHD ## [v1.0.1](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.0.1) -> February 2019. ## - Bug fix for the UE L1 simulator. ## [v1.0.0](https://gitlab.eurecom.fr/oai/openairinterface5g/-/tags/v1.0.0) -> January 2019. ## This version first implements the architectural split described in the following picture. ![Block Diagram](./doc/images/oai_lte_enb_func_split_arch.png) * Only FAPI, nFAPI and IF4.5 interfaces are implemented. * Repository tree structure prepares future integrations of features such as LTE-M, nbIOT or 5G-NR. * Preliminary X2 support has been implemented. * S1-flex has been introduced. * New tools: config library, telnet server, ... * A lot of bugfixes and a proper automated Continuous Integration process validates contributions. Old Releases: * v0.6.1 -> Mostly bugfixes. This is the last version without NFAPI. * v0.6 -> RRH functionality, UE greatly improved, better TDD support, a lot of bugs fixed. - WARNING: oaisim in PHY abstraction mode does not work, you need to use v0.5.2 for that. * v0.5.2 -> Last version with old code for oaisim (abstraction mode works) * v0.5.1 -> Merge of bugfix-137-uplink-fixes. It includes stablity fixes for eNB * v0.5 -> Merge of enhancement-10-harmony-lts. It includes fixes for Ubuntu 16.04 support * v0.4 -> Merge of feature-131-new-license. It closes issue#131 and changes the license to OAI Public License V1.0 * v0.3 -> Last stable commit on develop branch before the merge of feature-131-new-license. This is the last commit with GPL License * v0.2 -> Merge of enhancement-10-harmony to include NGFI RRH + New Interface for RF/BBU * v0.1 -> Last stable commit on develop branch before enhancement-10-harmony
