[srslte-users] srsRAN 21.04 Release Announcement

[Andre Puschmann]

Dear SDR hackers,

this is just to let you know that we've just tagged the final version of
srsRAN 21.04 [1]. This version fixes a few issues that have been
identified in the past two weeks. Those include:
* Fixed E-RAB to DRB mapping, especially handling for E-RAB IDs > 12
(thanks to Supreeth Herle)
* Fixed crash when UL info transfer is received for invalid S1AP ID
(thanks to Roberto Riggio for reporting)
* Fixed compilation on some 32bit machines, e.g. RPi2 and above (thanks
to Ralph A Schmid for reporting)

Enjoy the release.

Thanks again

srsRAN team
