  Bug First ver Fixed ver Description
  9.0.1 9.0 9.0.2130 Serious flaw in cluster_otus chimera detection. Do not use cluster_otus in v9.0.2124!
 
  9.0.2 9.0 9.0.2133 Labels generated by -relabel option of -cluster_otus had  gaps in the numbering, e.g. there might be Otu19 and Otu21 but no Otu20.
 
  9.0.3 9.0 9.0.2159 -annot failed to recognize some database hits that should be classified as "db_perfect", were identified as "other".
 
  9.0.4 9.0  9.0.2161 -unoise failed to include the abundance contribution of error-corrected input sequences with size < minampsize to the correct sequence abundance. The result is that the size= annotations in the output were systematically under-estimated. This should not usually matter much in practice.
 
  9.0.5 9.0 9.1 -cluster_agg command fatal error "Agg needs to be reimplemented".
 
  9.0.6 9.0    malloc.c:2372: sysmalloc: Assertion `(old_top == (((mbinptr) (((char *)... See Malloc bug in version 9 for workaround and discussion.
 
  9.0.7  9.1   unoise2 command produces empty -tabbout file.
 
  9.0.8 9.0    calc_distmx fatal error "SparseDistMx::ToFile not implemented". Workaround is to use v8.1.
