+2014-02-05 version 5.0
+
+This new major release adds some new features like incremental mode and SQL
+queries times histogram. There is also a hourly graphic representation of the
+count and average duration of top normalized queries. Same for errors or events,
+you will be able to see graphically at which hours they are occuring the most
+often.
+
+The incremental mode is an old request issued at PgCon Ottawa 2012 that concern
+the ability to construct incremental reports with successive runs of pgBadger.
+It is now possible to run pgbadger each days or even more, each hours, and have
+cumulatives reports per day and per week. A top index page allow you to go
+directly to the weekly and daily reports.
+
+This mode have been build with simplicity in mind so running pgbadger by cron
+as follow:
+
+ 0 23 * * * pgbadger -q -I -O /var/www/pgbadger/ /var/log/postgresql.log
+
+is enough to have daily and weelky reports viewable using your browser.
+
+You can take a look at a sample report at http://dalibo.github.io/pgbadger/demov5/index.html
+
+There's also a useful improvement to allow pgBadger to seek directly to the
+last position in the same log file after a successive execution. This feature
+is only available using the incremental mode or the -l option and parsing a
+single log file. Let's say you have a weekly rotated log file and want to run
+pgBadger each days. With 2GB of log per day, pgbadger was spending 5 minutes
+per block of 2 GB to reach the last position in the log, so at the end of the
+week this feature will save you 35 minutes. Now pgBadger will start parsing
+new log entries immediatly. This feature is compatible with the multiprocess
+mode using -j option (n processes for one log file).
+
+Histogram of query times is a new report in top queries slide that shows the
+query times distribution during the analyzed period. For example:
+
+ Range Count Percentage
+ --------------------------------------------
+ 0-1ms 10,367,313 53.52%
+ 1-5ms 799,883 4.13%
+ 5-10ms 451,646 2.33%
+ 10-25ms 2,965,883 15.31%
+ 25-50ms 4,510,258 23.28%
+ 50-100ms 180,975 0.93%
+ 100-500ms 87,613 0.45%
+ 500-1000ms 5,856 0.03%
+ 1000-10000ms 2,697 0.01%
+ > 10000ms 74 0.00%
+
+
+There is also some graphic and report improvements, like the mouse tracker
+formatting that have been reviewed. It now shows a vertical crosshair and
+all dataset values at a time when mouse pointer moves over series. Automatic
+queries formatting has also been changed, it is now done on double click
+event as simple click was painful when you want to copy some part of the
+queries.
+
+The report "Simultaneous Connections" has been relabeled into "Established
+Connections", it is less confusing as many people think that this is the number
+of simultaneous sessions, which is not the case. It only count the number of
+connections established at same time.
+
+Autovacuum reports now associate database name to the autovacuum and autoanalyze
+entries. Statistics now refer to "dbname.schema.table", previous versions was only
+showing the pair "schema.table".
+
+This release also adds Session peak information and a report about Simultaneous
+sessions. Parameters log_connections and log_disconnections must be enabled in
+postgresql.conf.
+
+Complete ChangeLog:
+
+ - Fix size of SQL queries columns to prevent exceeding screen width.
+ - Add new histogram reports on top normalized queries and top errors
+ or event. It shows at what hours and in which quantity the queries
+ or errors appears.
+ - Add seeking to last parser position in log file in incremental mode.
+ This prevent parsing all the file to find the last line parse from
+ previous run. This only works when parsing a single flat file, -j
+ option is permitted. Thanks to ioguix for the kick.
+ - Rewrite reloading of last log time from binary files.
+ - Fix missing statistics of last parsed queries in incremental mode.
+ - Fix bug in incremental mode that prevent reindexing a previous day.
+ Thanks to Martin Prochazka for the great help.
+ - Fix missing label "Avg duration" on column header in details of Most
+ frequent queries (N).
+ - Add vertical crosshair on graph.
+ - Fix case where queries and events was not updated when using -b and
+ -e command line. Thanks to Nicolas Thauvin for the report.
+ - Fix week sorting on incremental report main index page. Thanks to
+ Martin Prochazka for the report.
+ - Add "Histogram of query times" report to show statistics like
+ 0-100ms : 80%, 100-500ms :14%, 500-1000ms : 3%, > 1000ms : 1%.
+ Thanks to tmihail for the feature request.
+ - Format mouse tracker on graphs to show all dataset value at a time.
+ - Add control of -o vs -O option with incremental mode to prevent
+ wrong use.
+ - Change log level of missing LAST_PARSED.tmp file to WARNING and
+ add a HINT.
+ - Update copyright date to 2014
+ - Fix empty reports of connections. Thanks to Reeshna Ramakrishnan
+ for the report.
+ - Fix display of connections peak when no connection was reported.
+ - Fix warning on META_MERGE for ExtUtils::MakeMaker < 6.46. Thanks
+ to Julien Rouhaud for the patch.
+ - Add documentation about automatic incremental mode.
+ - Add incremental mode to pgBadger. This mode will build a report
+ per day and a cumulative report per week. It also create an index
+ interface to easiest access to the different report. Must be run,
+ for example, as:
+ pgbadger /var/log/postgresql.log.1 -I -O /var/www/pgbadger/
+ after a daily PostgreSQL log file rotation.
+ - Add -O | --outdir path to specify the directory where out file
+ must be saved.
+ - Automatic queries formatting is now done on double click event,
+ simple click was painful when you want to copy some part of the
+ queries. Thanks to Guillaume Smet for the feature request.
+ - Remove calls of binmode to force html file output to be utf8 as
+ there is some bad side effect. Thanks to akorotkov for the report.
+ - Remove use of Time::HiRes Perl module as some distributions does
+ not include this module by default in core Perl install.
+ - Fix "Wide character in print" Perl message by setting binmode
+ to :utf8. Thanks to Casey Allen Shobe for the report.
+ - Fix application name search regex to handle application name with
+ space like "pgAdmin III - Query Tool".
+ - Fix wrong timestamps saved with top queries. Thanks to Herve Werner
+ for the report.
+ - Fix missing logs types statitics when using binary mode. Thanks to
+ Herve Werner for the report.
+ - Fix Queries by application table column header: Database replaced
+ by Application. Thanks to Herve Werner for the report.
+ - Add "Max number of times the same event was reported" report in
+ Global stats Events tab.
+ - Replace "Number of errors" by "Number of ERROR entries" and add
+ "Number of FATAL entries".
+ - Replace "Number of errors" by "Number of events" and "Total errors
+ found" by "Total events found" in Events reports. Thanks to Herve
+ Werner for the report.
+ - Fix title error in Sessions per database.
+ - Fix clicking on the info link to not go back to the top of the page.
+ Thanks to Guillaume Smet for the report and solution.
+ - Fix incremental report from binary output where binary data was not
+ loaded if no queries were present in log file. Thanks to Herve Werner
+ for the report.
+ - Fix parsing issue when log_error_verbosity = verbose. Thanks to vorko
+ for the report.
+ - Add Session peak information and a report about Simultaneous sessions.
+ log_connections+log_disconnections must be enabled in postgresql.conf.
+ - Fix wrong requests number in Queries by user and by host. Thanks to
+ Jehan-Guillaume de Rorthais for the report.
+ - Fix issue with rsyslog format failing to parse logs. Thanks to Tim
+ Sampson for the report.
+ - Associate autovacuum and autoanalyze log entry to the corresponding
+ database name. Thanks to Herve Werner for the feature request.
+ - Change "Simultaneous Connections" label into "Established Connections",
+ it is less confusing as many people think that this is the number of
+ simultaneous sessions, which is not the case. It only count the number
+ of connections established at same time. Thanks to Ronan Dunklau for
+ the report.
