# Derive the choice of resolutions/statuses from the -All- data file
|

# Removed hardcoded order of resolutions/statuses when reading from
|
|
# daily stats file, so now works independently of collectstats.pl
|
|
# version
|
|
# Added image caching by date and datasets
|
|
# Myk Melez <myk@mozilla.org):
|
|
# Implemented form field validation and reorganized code.
