ChangeLog

version 0.8.4
	Added the triggered-regexp script
	Added the logtail utility and CLI

version 0.8.3
	Added explicit error message when --format is missing to AccessLog log parser
	Added uWSGIParser. Can now be used with logparse --parser uWSGIParser.
	Field names (for key-based -f lookup): 'ip', 'timestamp', 'method',
	'path', 'bytes', 'processing_time'.
	Added unit-test for the uWSGIParser
	Better exception handling for the logparse utility, now reports failure to match 
	used-specified --fields in more accurate manner, separate from failures in actual parsing of the logline.

version 0.8.2
	Updated dependecy on sqlsoup (separated out of sqlalchemy). Thanks to
	Robert Churchill for pointing it out.
	Update SqlAlchemy dependency version to latest stable release

version 0.8.1
    Fixes to logfilter to properly support --parser -based filtering
    Updated documentation and examples in README
    Cleanup and error checking to percentiles utility, fixed to work with osx
    mktemp

version 0.8
	Added the 'logfilter' utility with support for regexp/aho-corasick based matching. See README/documentation for examples
	Added the 'percentiles' utility for quickly computing percentiles out of input data
	Added unit-tests for the logfilter functionality
	Added dependency on the acora string matching library (Implements Aho-Corasick in CPython)
    Minor fixes to qps utility (formatting and parameter naming in README
    example)
    Updated README to be markdown based, cleaned up and edited
	
version 0.7.2
	Added missing -d and -f parameters to logsample for enabling weighted reservoir sampling
	Bugfix to geoip --filter default value triggering a filtering by default (regression introduced in in 0.7.1)

version 0.7.1
	Small fix with geoip --filter default value

version 0.7
	Added -q flag to urlparse (See README/documentation for examples)
	Added -f flag to geoip, allowing one to filter inplace for a specific country (e.g -f 'United States')
	Added --decode options to urlparse that allows one to url-decode (unquote) input stream
	Added sumstat utility/API for generating some common summary statistics for a given histogram-like logfile. See README for examples
	Added 'colsum' script utility that does an arithmetic summation over a column of data
	Added stripping of leading whitespace from output of 'aggregate' script
	Updated documentation, Added more examples for new utilities in README
	Updated unit-tests to reflect additions/changes to tools
	Unicode encoding in logplot line-plot using matplotlib backend (would crash with encoding problems in some cases)
	Unicode encoding for the logparse, fixes some cases of errors, e.g when using JSONParser for a JSON that has non-string types (e.g integers)
	Fixed bug in use of --ignore for logparse
	Default value for --delimiter is now ' ' across commands (logjoin etc.)
	
version 0.6
	Added --header flag to logparse, will prepend output with field names. useful e.g for dumping to CSV file
	Added --parser and --ip-ua-fields options to filterbots, allows routing input through a parser for filtering bots
	Updated logmerge to support indexed/named field-based merge-sorting when using --parser. See README for examples
	Added Histogram plot type support to logplot (--type hist)
	Added urlparse utility/API. See README for details
	Added logjoin utility/API. See README for details
	Added logtools.join_backends module with SQLAlchemy backend implementation (added sqlalchemy to install_requires)
	
version 0.5
	Added qps utility - Parse timestamps from log stream and calculate qps over sliding time window		
	Added Prefix/Suffix matching to filterbots - Specify p'<prefix>' or s'<suffix>' in useragents file to use this feature
	Added comment support for filterbots useragents/ips files - use '#' in start of line
	Added JSONParser to parsing module, can now use JSON-formatted logs e.g for logmerge, logparse etc.
	Added --ignore flag to logparse, surpresses missing field errors and skips those lines
	Added the 'timeseries' plot type for plotting timeseries data
	Added the matplotlib plotting backend supporting pie/line/timeseries charting
	Added data/examples subdirectory, included example bots_useragents.txt files	
	Can now specify fields by field name in -f parameter for the logparse method/console script
	Can now specify multiple comma-separated field names/indices in logparse method	
	Fixed memory bug resulting from un-needed use of readlines() on file descriptors
	Changed programmatic interface for most methods to use explicit parameter naming instead of generic (opts, args)
	Updated unit-tests, examples and README to reflect most of latest functionality	
	
version 0.4
	Added unit-testing for logtools.parsers module
	Fixed small bug in GeoIP unit-testing
	Fixed small bug in logplot option parsing from configuration file
