1. It's no need to modify LTE-RRC's ASN.1 file for enabling option group feature in generate_asn1. 2. It's no need to patch the C header files generated from LTE-RRC/S1AP/X2AP's ASN.1 in fix_asn1. 3. It's no need to pre-process S1AP/X2AP's ASN.1 for enabling information object class feature by asn1tostruct.py. This commit requires an un-official version of asn1c which are collaboration of asn1c community members and `build_helper` is modified in this commit accordingly : https://github.com/brchiu/asn1c/tree/velichkov_s1ap_plus_option_group This asn1c can also convert ASN.1 of 5G NR RRC (38.331, v15.1.0) and generate C files with -findirect-choice command line option without tweaking ASN.1 file. Examples for how to use this asn1c for S1AP are in S1AP files, e.g. s1ap_eNB_nas_procedures.c and s1ap_eNB_handler.c. There is an modified openair-cn (based on tag 0.5.0) with this new asn1c at : https://github.com/brchiu/openair-cn/tree/new-asn1c Basic S1AP interaction and data transfer operation between OAI eNB and this modified openair-cn has been tested. Note: Community version of asn1c is keeping evolved to provide better usage.

RELEASE NOTES:
v0.1 -> Last stable commit on develop branch before enhancement-10-harmony
v0.2 -> Merge of enhancement-10-harmony to include NGFI RRH + New Interface for RF/BBU
v0.3 -> Last stable commit on develop branch before the merge of feature-131-new-license. This is the last commit with GPL License
v0.4 -> Merge of feature-131-new-license. It closes issue#131 and changes the license to OAI Public License V1.0
v0.5 -> Merge of enhancement-10-harmony-lts. It includes fixes for Ubuntu 16.04 support
v0.5.1 -> Merge of bugfix-137-uplink-fixes. It includes stablity fixes for eNB
v0.5.2 -> Last version with old code for oaisim (abstraction mode works)
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.
v0.6.1 -> Mostly bugfixes. This is the last version without NFAPI.
