--------------------
+0.7.3 (2011-12-22)
+--------------------
+ * Scan window:
+ - items are now sorted first by channel (ascending) then by signal
+ strength (descending), as before
+ - using one line per entry doubled the capacity of the scan window
+ - refresh interval is made configurable (via 'Statistics updates')
+ * Configuration screen:
+ - memorizes the last-changed item to ease longer configuration tasks
+ * Fixes:
+ - better (cleaner) termination on error
+ - fixed clear-line refresh in info screen
+ - fixed bug in generator for random link quality (causing negative values)
+ - reverted using separate process group (problems when running under sudo)
+ - miscellaneous code reordering to decouple functional units
+
+--------------------
+0.7.2 (2011-02-25)
+--------------------
+ * General:
+ - support SIGWINCH for resizing (thanks to Koniu)
+ - reorganized screen handling to support resizing
+ - make geometry checking optional and off by default
+ - allow suspending wavemon (CTRL-Z) on most screens
+ * Info screen:
+ - suppress obvious broadcast address (deriving from prefix)
+ - special case for "no interface address assigned"
+ - display interface MTU if different from the default value
+ - show interface flags and TX queue length if enough space
+ * Scan window:
+ - set up enable interface if it is down (otherwise no scan)
+ - drop support for wireless extensions < 18 (minimum requirement)
+ - clean up child scan process on error (avoid garbled screen)
+ * Configuration screen:
+ - support 'Cisco-style' MAC addresses (dots rather than colons)
+ * Fixes:
+ - do not report zero bitrates (Info screen, 802.11n interface)
+ - remove unused timer in Scan window (data sampling is now
+ confined to info/histogram screens)
+ - fixed various compiler warnings
+ - fixed several problems in and improved the random generator
+ - use sigaction() rather than signal()
+ - miscellaneous reorganization of the configuration menu code
+
+--------------------
+0.7.1 (2010-12-24)
+--------------------
+ * Scan window:
+ - improved and more consistent formatting of entries
+ - better responsiveness by running scan operation as child process
+ * Security capabilities:
+ - display capabilities supported by the driver
+ - display current and available key sizes
+ - decode relevant IE information
+ * check and warn about insufficient permissions (CAP_NET_ADMIN) that
+ are required for several wireless operations (e.g. scanning)
+ * Bug Fixes:
+ - avoid triggering assertion on large screens
+ - require minimum version (18) of the wireless extensions
+ - better clearing of info screen
+ - various cleanups
+ * overhaul of manpages
+
+--------------------
+0.7.0 (2010-10-18)
+--------------------
+ * NEW Scan Window: this replaces the old access point screen. It displays
+ a sorted list (in descending order of signal quality) of access points
+ and other wireless clients within range, periodically refreshed at a
+ configurable rate.
+ * Access Point screen: finally deprecated this - the SIOCGIWAPLIST
+ ioctl itself is deprecated and works only on some older kernels.
+ * Info Window: clear screen to erase stale data.
+ * Bug Fixes: fixed a compiler warning in string-tolower operation.
+
+--------------------
+0.6.11 (2010-06-14)
+--------------------
+ * Info screen:
+ - fixed a bug in the freq/channel display: some drivers, such as ipw2100,
+ only return the channel number, requiring to look up the frequency;
+ - added a warning to indicate the absence of data from the interface.
+ * Histogram screen:
+ Tag the grid lines with the corresponding dBm levels:
+ - no levels are shown if there is no valid interface data (screen empty);
+ - level tags are restricted to the signal level graph only:
+ o if both signal and noise level data are valid, there are three graphs
+ (signal level, noise level, SNR), which would cause ambiguity,
+ o many cards (e.g. ath5k, rt73usb, iwl3945) do not supply noise data,
+ so that the histogram screen will then only contain the level graph;
+ - since the scale is adjustable, while the grid lines are fixed, the tags
+ are dynamically recomputed based on the y position and current scale;
+ - the min/max bounds of the scale are also shown.
+ Thanks to Sean Muir for this suggestion.
+ * Updated manpage regarding access point screen; as soon there is time, the
+ outdated and restricted SIOCGIWAPLIST ioctl should be replaced by a scan.
+
+--------------------
0.6.10 (2009-10-25)

.SH NAME
-wavemon \- a wireless network monitor application
+wavemon \- a wireless network monitor
.SH SYNOPSIS
.B wavemon [-h] [-i
.I ifname
.B ] [-l] [-r] [-v]
.SH DESCRIPTION
-.B wavemon
-is a ncurses-based monitoring application for wireless network devices. It displays continuously updated information about signal levels as well as wireless-specific and general network information. Currently, wavemon can be used for monitoring devices supported by the wireless extensions by Jean Tourrilhes <jt@hpl.hp.com>, included in kernels version 2.4 and higher.
+\fIwavemon\fR is a ncurses-based monitoring application for wireless network
+devices. It plots levels in real-time as well as showing wireless and network
+related device information. Currently, wavemon is still based on the wireless
+extensions by Jean Tourrilhes <jt@hpl.hp.com>.
-The wavemon interface is separated into several different sections, hereby referred to as "screens". Every screen displays information about distinct parameter types and/or in a special manner. For example, the "info" screen shows the current signal and noise levels as bargraphs, while the level histogram shows the exact same values as a level plot, so their development over time can be seen.
-On startup, you'll see one of the different monitor screens (which of the screens will actually be displayed depends on your configuration). On the bottom, you'll see a bar showing the available screens along with function key strokes.
-.LP
-These screens are currently implemented:
+The \fIwavemon\fR interface splits into different "screens".
+Each screen presents information in a specific manner. For example, the
+"info" screen shows current levels as bargraphs, whereas the "level" screen
+represents the same levels as a moving histogram.
+
+On startup, you'll see (depending on configuration) one of the different
+monitor screens. At the bottom, you'll find a \fImenu-bar\fR listing the
+screens and their function key names. The following screens can be selected:
.TP
.B Info (F1)
-This is the most "conclusive" of the monitor screens. It displays a condensed overview of all available wireless-specific parameters and network statistics, as well as bar graphs of the current signal and noise levels. There are several sub-sections to further separate the information.
+This is the most comprehensive screen. It displays a condensed overview of
+wireless-specific parameters and network statistics, as well as bar graphs.
+The layout is arranged into several sub-sections.
-At the
+The
.B Interface
-section, the name, ESSID and nickname of the current wireless interface are shown.
+section at the top shows information about the monitoring interface,
+including interface name, type, ESSID, and available encryption formats.
-Below, at the
+Below, in the
.B Levels
-section, you can see four bargraphs showing the quality of the link to the next station (if established), the level of the received signal, the current receiver's noise level and the signal-to-noise ration, which gives a good approximation of the overall signal quality. The colour of the signal level bargraph changes from red to yellow and green at fixed levels, while the colour of the noise level graph is adapted to the current signal level (it turns red when the signal-to-noise-ratio gets below 0dB). If the thresholds are associated with any actions, two arrows on the signal level graph will show the positions of the current thresholds. More on this topic later.
+section, you can see up to four bargraphs showing (1) relative signal quality
+and (2) signal level in dBm. If the wireless driver also supports noise level
+information, additionally (3) noise level in dBm and (4) Signal-Noise-Ratio
+(SNR) in dB are shown. The colour of the signal level bargraph changes
+from red to yellow and green at fixed levels. If thresholds have been set,
+two arrows on the signal level graph will show the positions of the current
+thresholds.
The
.B Statistics
-section displays packet and byte counters. The first four values, preceded RX and TX, show the current total number of packets received and transceived since the initialization of the interface. The following three values display the number of packets that were discarded from the interface because of invalid network ids, wrong encryption keys and other errors.
+section displays packet and byte counters and a few other packet-related
+statistics.
-Below, at the
+The subsequent
.B Info
-subsection, various wireless-specific parameters of the interface are displayed. What parameters are actually shown may vary and depends on the capabilities and the operation mode of your network device. The top line shows the current frequency the interface operates on, the sensitivity threshold of the receiver and the transmission power. Below, the operation mode of the interface (managed, ad-hoc...) and, if appropriate, the MAC address of the current access point are displayed. The third line shows the current data transfer speed in Mbit/s and the retransmission and fragmentation thresholds. Whether or not the details about encryption show up in the next line depends on the permissions of the user. Finally, the last line displays the power management parameters, if this feature is available and active.
+subsection lists the current operational mode and configuration of the
+wireless interface. What parameters are actually shown depends on the
+capabilities and selected mode of your network device.
-The last section, titled
-.B Network,
-shows - you guessed it - network parameters, such as the interface name and hardware address as well as the interface, netmask and broadcast IP addresses. These parameters are not wireless-related.
+Lastly, the
+.B Network
+section shows network-level parameters. The MAC-address is resolved from
+\fBethers\fR(5). The IPv4 address is shown in CIDR notation (RFC\ 4632
+\fIaddress\fR\fB/\fR\fIprefix_len\fR format). Since often those two values
+also determine the broadcast address (last 32 \- \fIprefix_len\fR bits set
+to 1), that address is shown only if it does not derive from the interface
+address and prefix length. Likewise, the interface MTU is shown only if it
+differs from the default Ethernet MTU of 1500 bytes.
-Another keyboard shortcut for this screen is 'i'.
+Another keyboard shortcut for this screen is '\fIi\fR'.
.TP
.B Level histogram (F2)
-This is a full-screen histogram plot of the signal/noise levels and the signal-to-noise levels. It shows the level changes with time. Below the plot, the key is shown. If available, the terminfo scanline chars are used in order to enhance the precision of the level plots, i.e. this screen will particularly look nifty in a xterm.
+This is a full-screen histogram plot showing the evolution of levels with time.
+The screen is partitioned into a grid, with dBm levels shown in green at
+the right hand side (depending on configuration). At the very minimum,
+the evolution of the signal-level is shown. If the wireless driver also
+supports noise-level information, additionally a noise graph and associated
+SNR graph appear.
.TP
-.B Access point list (F3)
-This screen provides a list of MAC addresses specifying the access points within range. This feature is currently _very_ rudimentary and may not even work for you. Stay tuned, as a more useable access point list is on its way.
+.B Scan window (F3)
+A periodically updated network scan, showing access points and other
+wireless clients, ordered by frequency and then descending order of signal
+quality. Each entry starts with the ESSID, followed by the colour-coded MAC
+address and the signal/channel information. A green/red MAC address indicates
+an (un-)encrypted access point, the colour changes to yellow for non-access
+points (in this case the mode is shown at the end of the line). The
+uncoloured information following the MAC address lists relative and
+absolute signal strengths, channel, frequency, and the mode if the node
+is not an access point.
+
+Please note that gathering meaningful scan data can take several seconds. Partly
+for this reason, the Scan window is the only screen that can not be suspended
+(CTRL-Z).
.TP
.B Preferences (F7)
-This screen allows you to change all program options such as interface and level scale parameters, and to save the new settings to the configuration file. Select a parameter with <up> and <down>, then change the value with <left> and <right>. Please refer to the
-.B wavemonrc
-man page for an in-depth description of all available settings.

.SH DESCRIPTION
-.B wavemon
-stores its configuration parameters within the file ~/.wavemonrc in every user's home directory. This manpage provides an in-depth description of the available options. Every setting corresponds to a configuration item you'll find on the preferences screen within the program (F7 key).
+\fIwavemonrc\fR is the per-user configuration file for \fBwavemon\fR(1).
+This page describes its individual configuration options. Each corresponds
