1.11 / 1-Jun-11 - Fix: Memory allocation was miscalculated when creating interface list from /sys/class/net when /proc/net/dev wasn't available which in turn could crash the daemon - Fix: Daemon database cache could remain empty after a -HUP signal - Fix: Don't make temp directory in vnstat.cgi writable for everyone - Import GNU/kFreeBSD support from Debian (#608963, patch by Mats Erik Andersson) - Remove usage of GNU only '-D' option for install for BSD in Makefile - The daemon now automatically creates databases for available interfaces if no databases are found during startup 1.10 / 2-Jan-10 - Fix: Buffer overflow was possible in hourly image output when RateUnit=1 and HourlyRate=1 - Fix: Minor memory leak was possible in the handling of HUP signal in daemon - Fix: Graphical elements weren't correctly aligned in summary image when header wasn't visible (-nh) - Fix: --delete didn't work - Possibility to merge statistics from several databases and save the end result to a new database (--mergesaved) - Added validation of database cache in daemon in order to be more robust in case of system memory corruption - Support for --style to -l (live mode) - Alternative print mode to -l (live mode) with optional parameter - Present options and elements in man pages in alphabetical order - Code cleanup 1.9 / 12-Sep-09 - Fix: TrafficlessDays configuration option was enabled when set to zero when it should have been disabled - Fix: MonthRotate setting was getting ignored for the first month if the database is created when day of month < MonthRotate value - Configurable summary layout in image output (1.7 <> 1.8 layouts) - --oneline, a simple parseable one line output - --transparent for setting image background transparency from the command line - --delete for deleting databases and stopping monitoring, doesn't require restarting the daemon - A database write can be configure to occur after interface status changes - Different database write interval can be configure to be used when all monitored interfaces are offline - Better configurability for the content of outputs, including a narrow output for space limited terminals (OutputStyle and --style) - Code cleanup - New configuration file settings: OutputStyle, SummaryLayout, SummaryRate, SaveOnStatusChange, OfflineSaveInterval 1.8 / 1-Aug-09 - Fix: OpenBSD print issues (was: ' used for formatting in sprintf) - Fix: Monthly estimate for February during a leap year was wrong - Fix: 'make install' didn't install the config file is $(DESTDIR) was used - Traffic of current and previous months added to summary - Increased accuracy of monthly estimate calculation - Traffic rates can be made visible and the shown unit is configurable as bits or bytes - New summary layout in image output - Image output can have the background color set as transparent - Possibility to merge data from several interfaces to one output with interface1+interface2 syntax - -s / --sync parameter added to daemon - --dbdir and --locale parameters added - Outputs now use system locale by default and formatting of dates follow the locale setting unless configured otherwise - New configuration file settings: ShowRate, RateUnit, TrafficlessDays, HourlyRate, TransparentBg 1.7 / 12-Apr-09 - Fix: Timezone changes shouldn't cause a flood of errors anymore - Fix: Statvfs used instead of statfs for BSD compatibility (Thanks to Mark Mitchell for pointing this out) - Fix: Makefile didn't properly support LDFLAGS and -lm was misplaced - Fix: MonthRotate value in config wasn't used - Fix: Unreadable configuration file doesn't cause a segmentation fault - Fix: /proc/net/dev parser didn't see the difference between eth10 and eth1 - Fix: Updating a database from two of more processes at the same time was able to sometimes cause data loss - Fix: Estimates are calculated based on last database update - Fix: Each interface update had a possibility of losing 1023 bytes of traffic at most due to improper rounding (Thanks to Michael Berlin for suggesting a suitable correction) - Daemon support as alternative for cron based updates - PNG image output (hourly rate based on patch by Sergio Ammirata) - XML output - BSD support - Diskspace check can be disabled from configuration file - IEC standard prefixes (KiB/MiB/GiB/TiB) - List of available interfaces if wrong of unavailable interface is selected 1.6 / 1-Jan-08 - Fix: Segmentation fault when environment variable "HOME" wasn't defined, this broke most CGI and PHP scripts that used vnStat - Support for /sys/class/net/* if /proc/net/dev is unavailable - Config file parser redesigned - --config parameter for selecting config file - Consistent exit status for all operations (0 for success, 1 for error) - Improved file locking - Man page restrictions paragraph updated - Minor non-visible fixes and code cleanup 1.5 / 3-Dec-07 - Fix: compile time warnings solved - Fix: kernel test is now more verbose - Fix: more informative error messages - Fix: possible division by zero for traffic estimates right after midnight - Fix: interface names longer than 6 chars (patch by Jan Schmidle) - Realtime transfer rate mode - Automatic 32bit/64bit counter detection - Config file support - Internal database backups and locking - More visuals in outputs - Adaptive units (kB, MB, GB, TB) - Possibility to sync counters without counting traffic - Maximum bandwidth of interfaces can be set 1.4 / 26-Mar-04 - Fix: major output problems when compiled with some compilers (thanks to DukePyrolator for reporting this bug and Juha / vlu for testing the patch) - Fix: month rotation if database isn't updated every day - Minor non-visible fixes and code cleanup 1.3 / 8-Mar-04 - Fix: support for 64bit counters - Fix: 'yesterday' was showing 01.01. with new databases - Fix: free space warning changed from 1% to 1MB - Fix: minor security exploit - A man page has been included - Hourly output with textgraphical view - kBs are visible when traffic is under 1000 MB - Webpage moved to http://humdi.net/vnstat/ - Minor visual updates 1.2 / 7-Oct-03 - Changed file paths to conform with FHS (http://www.pathname.com/fhs/) /usr/local/bin/vnstat -> /usr/bin/vnstat /var/spool/vnstat -> /var/lib/vnstat - Added FAQ - Included sample scripts for pppd users - Support for 64bit counters in /proc/net/dev (Thanks to Stephan van Hienen for the test account) - Actual date is shown if the previous day in the database isn't yesterday - Weekly and last 7 days traffic can be shown. (Thanks to Derk-Jan Hartman for the suggestion) - Average kB/s meter - --testkernel fixed - Documentation for --dumpdb included in the README 1.1 / 13-Jul-03 - Support for multiple interfaces - Date checking (update shouldn't be before previous update) - New database structure - Possibility to change date output format - Test tool for faulty kernels - Parseable output - Better support for ppp/dsl users - Free diskspace check - Possibility to change month rotation day (like 25. instead of 1.) - Daily/monthly traffic estimation 22-Nov-02 - Renamed the cron script file that would be installed to /etc/cron.d from vnstat.cron to vnstat because debian systems didn't execute scripts containing dots (Thanks to frangen / Simo Salminen for this note) 1.0 / 23-Sep-02 - Initial public release
