README_AGP_FORMAT_CHANGE from ftp://ftp.ncbi.nih.gov/genomes

January 9, 2012

**********************************************************************

NCBI is switching from using the old version of the AGP specification
(version 1.1) to using the new version (version 2.0) because the 
latter can convey valuable information on the nature of the evidence 
linking sequences on either side of a gap. This change will affect 
users who obtain AGP files from the NCBI FTP site.

Timeline:
2012 Feb 10 	AGP files will be written in 2.0 format.

Starting on February 10, 2012, the AGP files that NCBI posts on this 
FTP site will be written in v2.0 format. These v2.0 AGPs can be 
identified by the header line: "##agp-version 2.0". AGP parsers will 
require slight modification to enable them to read v2.0 AGPs (see list
of changes from v1.1 to v2.0 in the AGP v2.0 specification). Existing
AGP files already on the FTP site will not be updated, they will 
remain in v1.1 format.

See the following web pages for more details.
