• Remove -e (encoding) and -r (reclen) options, these are autodetected
• Remove the -M and -R options
• Add -m and -r options to match and reject patterns against the Source Identifier of each record, often following this pattern: FDSN:<network>_<station>_<location>_<band>_<source>_<subsource>
• Replace the -y option with -snd and change the default to stop processing if non-miniSEED is encountered.
• Filenames can now contain read range with end: file@start-end
• Added -H option to add HTTP headers
