 ### Bug fixes
 
+* Certain strain names would be silently renamed by `augur tree [--method iqtree]`. We now avoid such renaming wherever possible and in cases where there are backslashes or single quotes we now raise a fatal error.
+Note that names with spaces in the FASTA header (description line) continue to be modified such that everything after the first space is not used in the resulting tree. [#1750][] (@jameshadfield)
 * Fixed the error that occurred when running `augur curate --help`. [#1755][] (@joverlee521)
