GI numbers will be removed from sequence record presentations

As announced in March 2016, NCBI is now in the process of removing GI numbers from the presentations of nucleotide and protein sequence records. The affected presentations are the (default) flat file (GenBank and GenPept) views, along with FASTA views. NCBI will be releasing these changes on or soon after October 17, 2016.
