@@ -99,6 +99,7 @@ and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.
 - Added a few missing header files in shortlist.h and beam_search.h.
 - Improved handling for receiving SIGTERM during training. By default, SIGTERM triggers 'save (now) and exit'. Prior to this fix, batch pre-fetching did not check for this sigal, potentially delaying exit considerably. It now pays attention to that. Also, the default behaviour of save-and-exit can now be disabled on the command line with --sigterm exit-immediately.
 - Fix the runtime failures for FASTOPT on 32-bit builds (wasm just happens to be 32-bit) because it uses hashing with an inconsistent mix of uint64_t and size_t.
+- fix beam_search ABORT_IF(beamHypIdx >= beam.size(), "Out of bounds beamHypIdx??"); when enable openmp and OMP_NUM_THREADS > 1
 
 ### Changed
 - Remove `--clip-gemm` which is obsolete and was never used anyway
