+## Flot 0.8.3 ##
+
+### Changes ###
+
+- Updated example code to avoid encouraging unnecessary re-plots.
+  (patch by soenter, pull request #1221)
+
+### Bug fixes ###
+
+ - Added a work-around to disable the allocation of extra space for first and
+   last axis ticks, allowing plots to span the full width of their container.
+   A proper solution for this bug will be implemented in the 0.9 release.
+   (reported by Josh Pigford and andig, issue #1212, pull request #1290)
+
+ - Fixed a regression introduced in 0.8.1, where the last tick label would
+   sometimes wrap rather than extending the plot's offset to create space.
+   (reported by Elite Gamer, issue #1283)
+
+ - Fixed a regression introduced in 0.8.2, where the resize plugin would use
+   unexpectedly high amounts of CPU even when idle.
+   (reported by tommie, issue #1277, pull request #1289)
+
+ - Fixed the selection example to work with jQuery 1.9.x and later.
+   (reported by EGLadona and dmfalke, issue #1250, pull request #1285)
+
+ - Added a detach shim to fix support for jQuery versions earlier than 1.4.x.
+   (reported by ngavard, issue #1240, pull request #1286)
+
+ - Fixed a rare 'Uncaught TypeError' when using the resize plugin in IE 7/8.
+   (reported by tleish, issue #1265, pull request #1289)
+
+ - Fixed zoom constraints to apply only in the direction of the zoom.
+   (patch by Neil Katin, issue #1204, pull request #1205)
+
+ - Markings lines are no longer blurry when drawn on pixel boundaries.
+   (reported by btccointicker and Rouillard, issue #1210)
+
+ - Don't discard original pie data-series values when combining slices.
+   (patch by Phil Tsarik, pull request #1238)
+
+ - Fixed broken auto-scale behavior when using deprecated [x|y]2axis options.
+   (reported by jorese, issue #1228, pull request #1284)
+
+ - Exposed the dateGenerator function on the plot object, as it used to be
+   before time-mode was moved into a separate plugin.
+   (patch by Paolo Valleri, pull request #1028)
+
+
+## Flot 0.8.2 ##
+
+### Changes ###
+
+ - Added a plot.destroy method as a way to free memory when emptying the plot
+   placeholder and then re-using it for some other purpose.
+   (patch by Thodoris Greasidis, issue #1129, pull request #1130)
+
+ - Added a table of contents and PLUGINS link to the API documentation.

+
+ - Updated inlined jQuery Resize to the latest version to fix errors.
+   (reported by Matthew Sabol and sloker, issues #997 ad #1081)
+
+### Bug fixes ###
+
+ - Fixed an unexpected change in behavior that resulted in duplicate tick
+   labels when using a plugin, like flot-tickrotor, that overrode tick labels.
+   (patch by Mark Cote, pull request #1091)
+
+ - Fixed a regression from 0.7 where axis labels were given the wrong width,
+   causing them to overlap at certain scales and ignore the labelWidth option.
+   (patch by Benjamin Gram, pull request #1177)
+
+ - Fixed a bug where the second axis in an xaxes/yaxes array incorrectly had
+   its 'innermost' property set to false or undefined, even if it was on the
+   other side of the plot from the first axis. This resulted in the axis bar
+   being visible when it shouldn't have been, which was especially obvious
+   when the grid had a left/right border width of zero.
+   (reported by Teq1, fix researched by ryleyb, issue #1056)
+
+ - Fixed an error when using a placeholder that has no font-size property.
+   (patch by Craig Oldford, pull request #1135)
+
+ - Fixed a regression from 0.7 where nulls at the end of a series were ignored
+   for purposes of determing the range of the x-axis.
+   (reported by Munsifali Rashid, issue #1095)
+
+ - If a font size is provided, base the default lineHeight on that size rather
+   that the font size of the plot placeholder, which may be very different.
+   (reported by Daniel Hoffmann Bernardes, issue #1131, pull request #1199)
+
+ - Fix broken highlighting for right-aligned bars.
+   (reported by BeWiBu and Mihai Stanciu, issues #975 and #1093, with further
+   assistance by Eric Byers, pull request #1120)
+
+ - Prevent white circles from sometimes showing up inside of pie charts.
+   (reported by Pierre Dubois and Jack Klink, issues #1128 and #1073)
+
+ - Label formatting no longer breaks when a page contains multiple pie charts.
+   (reported by Brend Wanders, issue #1055)
+
+ - When using multiple axes on opposite sides of the plot, the innermost axis
+   coming later in the list no longer has its bar drawn incorrectly.
+   (reported by ryleyb, issue #1056)
+
+ - When removing series labels and redrawing the plot, the legend now updates
+   correctly even when using an external container.
+   (patch by Luis Silva, issue #1159, pull request #1160)
+
+ - The pie plugin no longer ignores the value of the left offset option.
+   (reported by melanker, issue #1136)
+
+ - Fixed a regression from 0.7, where extra padding was added unnecessarily to
+   sides of the plot where there was no last tick label.
+   (reported by sknob001, issue #1048, pull request #1200)
+
+ - Fixed incorrect tooltip behavior in the interacting example.
+   (patch by cleroux, issue #686, pull request #1074)

+   (reported by irbian, issue #915)
+
+## Flot 0.8.1 ##
+
+### Bug fixes ###
+
+ - Fixed a regression in the time plugin, introduced in 0.8, that caused dates
+   to align to the minute rather than to the highest appropriate unit. This
+   caused many x-axes in 0.8 to have different ticks than they did in 0.7.
+   (reported by Tom Sheppard, patch by Daniel Shapiro, issue #1017, pull
+   request #1023)
+
+ - Fixed a regression in text rendering, introduced in 0.8, that caused axis
+   labels with the same text as another label on the same axis to disappear.
+   More generally, it's again possible to have the same text in two locations.
+   (issue #1032)
+
+ - Fixed a regression in text rendering, introduced in 0.8, where axis labels
+   were no longer assigned an explicit width, and their text could not wrap.
+   (reported by sabregreen, issue #1019)
+
+ - Fixed a regression in the pie plugin, introduced in 0.8, that prevented it
+   from accepting data in the format '[[x, y]]'.
+   (patch by Nicolas Morel, pull request #1024)
+
+ - The 'zero' series option and 'autoscale' format option are no longer
+   ignored when the series contains a null value.
+   (reported by Daniel Shapiro, issue #1033)
+
+ - Avoid triggering the time-mode plugin exception when there are zero series.
+   (reported by Daniel Rothig, patch by Mark Raymond, issue #1016)
+
+ - When a custom color palette has fewer colors than the default palette, Flot
+   no longer fills out the colors with the remainder of the default.
+   (patch by goorpy, issue #1031, pull request #1034)
+
+ - Fixed missing update for bar highlights after a zoom or other redraw.
+   (reported by Paolo Valleri, issue #1030)
+
+ - Fixed compatibility with jQuery versions earlier than 1.7.
+   (patch by Lee Willis, issue #1027, pull request #1027)
+
+ - The mouse wheel no longer scrolls the page when using the navigate plugin.
+   (patch by vird, pull request #1020)
+
+ - Fixed missing semicolons in the core library.
+   (reported by Michal Zglinski)
+
+
+## Flot 0.8.0 ##
+
+### API changes ###
+
+Support for time series has been moved into a plugin, jquery.flot.time.js.
+This results in less code if time series are not used. The functionality
+remains the same (plus timezone support, as described below); however, the
+plugin must be included if axis.mode is set to "time".
+
+When the axis mode is "time", the axis option "timezone" can be set to null,
+"browser", or a particular timezone (e.g. "America/New_York") to control how
+the dates are displayed. If null, the dates are displayed as UTC. If
+"browser", the dates are displayed in the time zone of the user's browser.
+
+Date/time formatting has changed and now follows a proper subset of the
+standard strftime specifiers, plus one nonstandard specifier for quarters.
+Additionally, if a strftime function is found in the Date object's prototype,
+it will be used instead of the built-in formatter.
+
+Axis tick labels now use the class 'flot-tick-label' instead of 'tickLabel'.
+The text containers  for each axis now use the classes 'flot-[x|y]-axis' and
+'flot-[x|y]#-axis' instead of '[x|y]Axis' and '[x|y]#Axis'. For compatibility
+with Flot 0.7 and earlier text will continue to use the old classes as well,
+but they are considered deprecated and will be removed in a future version.
+
+In previous versions the axis 'color' option was used to set the color of tick
+marks and their label text. It now controls the color of the axis line, which
+previously could not be changed separately, and continues to act as a default
+for the tick-mark color.  The color of tick label text is now set either by
+overriding the 'flot-tick-label' CSS rule or via the axis 'font' option.
+
+A new plugin, jquery.flot.canvas.js, allows axis tick labels to be rendered
+directly to the canvas, rather than using HTML elements. This feature can be
+toggled with a simple option, making it easy to create interactive plots in the
+browser using HTML, then re-render them to canvas for export as an image.
+
+The plugin tries to remain as faithful as possible to the original HTML render,
+and goes so far as to automatically extract styles from CSS, to avoid having to
+provide a separate set of styles when rendering to canvas. Due to limitations
+of the canvas text API, the plugin cannot reproduce certain features, including
+HTML markup embedded in labels, and advanced text styles such as 'em' units.
+
+The plugin requires support for canvas text, which may not be present in some
+older browsers, even if they support the canvas tag itself. To use the plugin
+with these browsers try using a shim such as canvas-text or FlashCanvas.
+
+The base and overlay canvas are now using the CSS classes "flot-base" and
+"flot-overlay" to prevent accidental clashes (issue 540).

+   (patch by David Schnur, issues #316, #529, and #856, pull request #911)
+
+ - The plot function is now also a jQuery chainable property.
+   (patch by David Schnur, issues #734 and #816, pull request #953)

+ - When only a single pie slice is beneath the combine threshold it is no longer
+   replaced by an 'other' slice. (suggested by Devin Bayer, issue #638)
+
+ - Added lineJoin and minSize options to the selection plugin to control the

+
+## Flot 0.7 ##
+
+### API changes ###
+
+Multiple axes support. Code using dual axes should be changed from using
+x2axis/y2axis in the options to using an array (although backwards-
+compatibility hooks are in place). For instance,
+
+```js
+{
+    xaxis: { ... }, x2axis: { ... },
+    yaxis: { ... }, y2axis: { ... }
+}
+```
+
+becomes
+
+```js
+{
+    xaxes: [ { ... }, { ... } ],
+    yaxes: [ { ... }, { ... } ]
+}
+```
+
+Note that if you're just using one axis, continue to use the xaxis/yaxis
+directly (it now sets the default settings for the arrays). Plugins touching
+the axes must be ported to take the extra axes into account, check the source
+to see some examples.
+
+A related change is that the visibility of axes is now auto-detected. So if
+you were relying on an axis to show up even without any data in the chart, you
+now need to set the axis "show" option explicitly.
+
+"tickColor" on the grid options is now deprecated in favour of a corresponding
+option on the axes, so:
+
+```js
+{ grid: { tickColor: "#000" }}
+```
+
+becomes
+
+```js
+{ xaxis: { tickColor: "#000"}, yaxis: { tickColor: "#000"} }
+```
+
+But if you just configure a base color Flot will now autogenerate a tick color
+by adding transparency. Backwards-compatibility hooks are in place.
+
+Final note: now that IE 9 is coming out with canvas support, you may want to
+adapt the excanvas include to skip loading it in IE 9 (the examples have been
+adapted thanks to Ryley Breiddal). An alternative to excanvas using Flash has
+also surfaced, if your graphs are slow in IE, you may want to give it a spin:
+
+    http://code.google.com/p/flashcanvas/
+
+### Changes ###
+
+ - Support for specifying a bottom for each point for line charts when filling
+   them, this means that an arbitrary bottom can be used instead of just the x
+   axis. (based on patches patiently provided by Roman V. Prikhodchenko)
+
+ - New fillbetween plugin that can compute a bottom for a series from another
+   series, useful for filling areas between lines.
+
+   See new example percentiles.html for a use case.
+
+ - More predictable handling of gaps for the stacking plugin, now all
+   undefined ranges are skipped.
+
+ - Stacking plugin can stack horizontal bar charts.
+
+ - Navigate plugin now redraws the plot while panning instead of only after
+   the fact. (raised by lastthemy, issue 235)
+
+   Can be disabled by setting the pan.frameRate option to null.
+
+ - Date formatter now accepts %0m and %0d to get a zero-padded month or day.
+   (issue raised by Maximillian Dornseif)
+
+ - Revamped internals to support an unlimited number of axes, not just dual.
+   (sponsored by Flight Data Services, www.flightdataservices.com)
+
+ - New setting on axes, "tickLength", to control the size of ticks or turn
+   them off without turning off the labels.
+
+ - Axis labels are now put in container divs with classes, for instance labels
+   in the x axes can be reached via ".xAxis .tickLabel".
+
+ - Support for setting the color of an axis. (sponsored by Flight Data
+   Services, www.flightdataservices.com)
+
+ - Tick color is now auto-generated as the base color with some transparency,
+   unless you override it.
+
+ - Support for aligning ticks in the axes with "alignTicksWithAxis" to ensure
+   that they appear next to each other rather than in between, at the expense
+   of possibly awkward tick steps. (sponsored by Flight Data Services,
+   www.flightdataservices.com)
+
+ - Support for customizing the point type through a callback when plotting
+   points and new symbol plugin with some predefined point types. (sponsored
+   by Utility Data Corporation)
+
+ - Resize plugin for automatically redrawing when the placeholder changes
+   size, e.g. on window resizes. (sponsored by Novus Partners)
+
+   A resize() method has been added to plot object facilitate this.
+
+ - Support Infinity/-Infinity for plotting asymptotes by hacking it into
+   +/-Number.MAX_VALUE. (reported by rabaea.mircea)
+
+ - Support for restricting navigate plugin to not pan/zoom an axis. (based on
+   patch by kkaefer)
+
+ - Support for providing the drag cursor for the navigate plugin as an option.
+   (based on patch by Kelly T. Moore)
+
+ - Options for controlling whether an axis is shown or not (suggestion by Timo
+   Tuominen) and whether to reserve space for it even if it isn't shown.
+
+ - New attribute $.plot.version with the Flot version as a string.
+
+ - The version comment is now included in the minified jquery.flot.min.js.
+
+ - New options.grid.minBorderMargin for adjusting the minimum margin provided
+   around the border (based on patch by corani, issue 188).
+
+ - Refactor replot behaviour so Flot tries to reuse the existing canvas,
+   adding shutdown() methods to the plot. (based on patch by Ryley Breiddal,
+   issue 269)
+   
+   This prevents a memory leak in Chrome and hopefully makes replotting faster
+   for those who are using $.plot instead of .setData()/.draw(). Also update
+   jQuery to 1.5.1 to prevent IE leaks fixed in jQuery.
+
+ - New real-time line chart example.
+
+ - New hooks: drawSeries, shutdown.
+
+### Bug fixes ###
+
+ - Fixed problem with findNearbyItem and bars on top of each other. (reported
+   by ragingchikn, issue 242)
+
+ - Fixed problem with ticks and the border. (based on patch from
+   ultimatehustler69, issue 236)
+
+ - Fixed problem with plugins adding options to the series objects.
+
+ - Fixed a problem introduced in 0.6 with specifying a gradient with:
+
+   ```{brightness: x, opacity: y }```
+
+ - Don't use $.browser.msie, check for getContext on the created canvas element
+   instead and try to use excanvas if it's not found.
+
+   Fixes IE 9 compatibility.
+
+ - highlight(s, index) was looking up the point in the original s.data instead
+   of in the computed datapoints array, which breaks with plugins that modify
+   the datapoints, such as the stacking plugin. (reported by curlypaul924,
+   issue 316)
+
+ - More robust handling of axis from data passed in from getData(). (reported)
+   by Morgan)
+
+ - Fixed problem with turning off bar outline. (fix by Jordi Castells,
+   issue 253)
+
+ - Check the selection passed into setSelection in the selection
+   plugin, to guard against errors when synchronizing plots (fix by Lau
+   Bech Lauritzen).
+
+ - Fix bug in crosshair code with mouseout resetting the crosshair even

+
+
+## Flot 0.6 ##
+
+### API changes ###
+
+Selection support has been moved to a plugin. Thus if you're passing
+selection: { mode: something }, you MUST include the file
+jquery.flot.selection.js after jquery.flot.js. This reduces the size of
+base Flot and makes it easier to customize the selection as well as
+improving code clarity. The change is based on a patch from andershol.
+
+In the global options specified in the $.plot command, "lines", "points",
+"bars" and "shadowSize" have been moved to a sub-object called "series":
+
+```js
+$.plot(placeholder, data, { lines: { show: true }})
+```
+
+should be changed to
+
+```js
+  $.plot(placeholder, data, { series: { lines: { show: true }}})
+```
+
+All future series-specific options will go into this sub-object to
+simplify plugin writing. Backward-compatibility code is in place, so
+old code should not break.
+
+"plothover" no longer provides the original data point, but instead a
+normalized one, since there may be no corresponding original point.
+
+Due to a bug in previous versions of jQuery, you now need at least
+jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some improvements
+in event handling speed.
+
+## Changes ##
+
+ - Added support for disabling interactivity for specific data series.
+   (request from Ronald Schouten and Steve Upton)
+
+ - Flot now calls $() on the placeholder and optional legend container passed
+   in so you can specify DOM elements or CSS expressions to make it easier to
+   use Flot with libraries like Prototype or Mootools or through raw JSON from
+   Ajax responses.
+
+ - A new "plotselecting" event is now emitted while the user is making a
+   selection.
+
+ - The "plothover" event is now emitted immediately instead of at most 10
+   times per second, you'll have to put in a setTimeout yourself if you're
+   doing something really expensive on this event.
+
+ - The built-in date formatter can now be accessed as $.plot.formatDate(...)
+   (suggestion by Matt Manela) and even replaced.
+
+ - Added "borderColor" option to the grid. (patches from Amaury Chamayou and
+   Mike R. Williamson)
+
+ - Added support for gradient backgrounds for the grid. (based on patch from
+   Amaury Chamayou, issue 90)
+
+   The "setting options" example provides a demonstration.
+
+ - Gradient bars. (suggestion by stefpet)
+  
+ - Added a "plotunselected" event which is triggered when the selection is
+   removed, see "selection" example. (suggestion by Meda Ugo)
+
+ - The option legend.margin can now specify horizontal and vertical margins
+   independently. (suggestion by someone who's annoyed)
+
+ - Data passed into Flot is now copied to a new canonical format to enable
+   further processing before it hits the drawing routines. As a side-effect,
+   this should make Flot more robust in the face of bad data. (issue 112)
+
+ - Step-wise charting: line charts have a new option "steps" that when set to
+   true connects the points with horizontal/vertical steps instead of diagonal
+   lines.
+
+ - The legend labelFormatter now passes the series in addition to just the
+   label. (suggestion by Vincent Lemeltier)
+
+ - Horizontal bars (based on patch by Jason LeBrun).
+
+ - Support for partial bars by specifying a third coordinate, i.e. they don't
+   have to start from the axis. This can be used to make stacked bars.
+
+ - New option to disable the (grid.show).
+
+ - Added pointOffset method for converting a point in data space to an offset
+   within the placeholder.
+  
+ - Plugin system: register an init method in the $.flot.plugins array to get
+   started, see PLUGINS.txt for details on how to write plugins (it's easy).
+   There are also some extra methods to enable access to internal state.
+
+ - Hooks: you can register functions that are called while Flot is crunching
+   the data and doing the plot. This can be used to modify Flot without
+   changing the source, useful for writing plugins. Some hooks are defined,
+   more are likely to come.
+  
+ - Threshold plugin: you can set a threshold and a color, and the data points
+   below that threshold will then get the color. Useful for marking data
+   below 0, for instance.
+
+ - Stack plugin: you can specify a stack key for each series to have them
+   summed. This is useful for drawing additive/cumulative graphs with bars and
+   (currently unfilled) lines.
+
+ - Crosshairs plugin: trace the mouse position on the axes, enable with
+   crosshair: { mode: "x"} (see the new tracking example for a use).
+
+ - Image plugin: plot prerendered images.
+
+ - Navigation plugin for panning and zooming a plot.
+
+ - More configurable grid.
+
+ - Axis transformation support, useful for non-linear plots, e.g. log axes and
+   compressed time axes (like omitting weekends).
+
+ - Support for twelve-hour date formatting (patch by Forrest Aldridge).
+
+ - The color parsing code in Flot has been cleaned up and split out so it's
+   now available as a separate jQuery plugin. It's included inline in the Flot
+   source to make dependency managing easier. This also makes it really easy
+   to use the color helpers in Flot plugins.
+
+## Bug fixes ##
+
+ - Fixed two corner-case bugs when drawing filled curves. (report and analysis
+   by Joshua Varner)
+
+ - Fix auto-adjustment code when setting min to 0 for an axis where the
+   dataset is completely flat on that axis. (report by chovy)
+
+ - Fixed a bug with passing in data from getData to setData when the secondary
+   axes are used. (reported by nperelman, issue 65)
+
+ - Fixed so that it is possible to turn lines off when no other chart type is
+   shown (based on problem reported by Glenn Vanderburg), and fixed so that
+   setting lineWidth to 0 also hides the shadow. (based on problem reported by
+   Sergio Nunes)
+
+ - Updated mousemove position expression to the latest from jQuery. (reported
+   by meyuchas)
+
+ - Use CSS borders instead of background in legend. (issues 25 and 45)
+
+ - Explicitly convert axis min/max to numbers.
+
+ - Fixed a bug with drawing marking lines with different colors. (reported by
+   Khurram)
+
+ - Fixed a bug with returning y2 values in the selection event. (fix by
+   exists, issue 75)
+
+ - Only set position relative on placeholder if it hasn't already a position
+   different from static. (reported by kyberneticist, issue 95)
+
+ - Don't round markings to prevent sub-pixel problems. (reported by
+   Dan Lipsitt)
+
+ - Make the grid border act similarly to a regular CSS border, i.e. prevent
+   it from overlapping the plot itself. This also fixes a problem with anti-
+   aliasing when the width is 1 pixel. (reported by Anthony Ettinger)
+
+ - Imported version 3 of excanvas and fixed two issues with the newer version.
+   Hopefully, this will make Flot work with IE8. (nudge by Fabien Menager,
+   further analysis by Booink, issue 133)
+
+ - Changed the shadow code for lines to hopefully look a bit better with
+   vertical lines.
+
+ - Round tick positions to avoid possible problems with fractions. (suggestion
+   by Fred, issue 130)
+
+ - Made the heuristic for determining how many ticks to aim for a bit smarter.
+
+ - Fix for uneven axis margins (report and patch by Paul Kienzle) and snapping
+   to ticks. (report and patch by lifthrasiir)
+
+ - Fixed bug with slicing in findNearbyItems. (patch by zollman)
+
+ - Make heuristic for x axis label widths more dynamic. (patch by
+   rickinhethuis)
+
+ - Make sure points on top take precedence when finding nearby points when
+   hovering. (reported by didroe, issue 224)
+
+
+
+## Flot 0.5 ##
+
+Timestamps are now in UTC. Also "selected" event -> becomes "plotselected"
+with new data, the parameters for setSelection are now different (but
+backwards compatibility hooks are in place), coloredAreas becomes markings
+with a new interface (but backwards compatibility hooks are in place).
+
+### API changes ###
+
+Timestamps in time mode are now displayed according to UTC instead of the time
+zone of the visitor. This affects the way the timestamps should be input;
+you'll probably have to offset the timestamps according to your local time
+zone. It also affects any custom date handling code (which basically now
+should use the equivalent UTC date mehods, e.g. .setUTCMonth() instead of
+.setMonth().
+
+Markings, previously coloredAreas, are now specified as ranges on the axes,
+like ```{ xaxis: { from: 0, to: 10 }}```. Furthermore with markings you can
+now draw horizontal/vertical lines by setting from and to to the same
+coordinate. (idea from line support patch by by Ryan Funduk)
+
+Interactivity: added a new "plothover" event and this and the "plotclick"
+event now returns the closest data item (based on patch by /david, patch by
+Mark Byers for bar support). See the revamped "interacting with the data"
+example for some hints on what you can do.
+
+Highlighting: you can now highlight points and datapoints are autohighlighted
+when you hover over them (if hovering is turned on).
+
+Support for dual axis has been added (based on patch by someone who's annoyed
+and /david). For each data series you can specify which axes it belongs to,
+and there are two more axes, x2axis and y2axis, to customize. This affects the
+"selected" event which has been renamed to "plotselected" and spews out
+```{ xaxis: { from: -10, to: 20 } ... },``` setSelection in which the
+parameters are on a new form (backwards compatible hooks are in place so old
+code shouldn't break) and markings (formerly coloredAreas).
+
+## Changes ##
+
+ - Added support for specifying the size of tick labels (axis.labelWidth,
+   axis.labelHeight). Useful for specifying a max label size to keep multiple
+   plots aligned.
+
+ - The "fill" option can now be a number that specifies the opacity of the
+   fill.
+
+ - You can now specify a coordinate as null (like [2, null]) and Flot will
+   take the other coordinate into account when scaling the axes. (based on
+   patch by joebno)
+
+ - New option for bars "align". Set it to "center" to center the bars on the
+   value they represent.
+
+ - setSelection now takes a second parameter which you can use to prevent the
+   method from firing the "plotselected" handler. 
+
+ - Improved the handling of axis auto-scaling with bars. 
+
+## Bug fixes ##
+
+ - Fixed a bug in calculating spacing around the plot. (reported by
+   timothytoe)
+
+ - Fixed a bug in finding max values for all-negative data sets.
+ 
+ - Prevent the possibility of eternal looping in tick calculations.
+
+ - Fixed a bug when borderWidth is set to 0. (reported by Rob/sanchothefat)
+
+ - Fixed a bug with drawing bars extending below 0. (reported by James Hewitt,
+   patch by Ryan Funduk).
+
+ - Fixed a bug with line widths of bars. (reported by MikeM)
+
+ - Fixed a bug with 'nw' and 'sw' legend positions.
+
+ - Fixed a bug with multi-line x-axis tick labels. (reported by Luca Ciano,
+   IE-fix help by Savage Zhang)
+
+ - Using the "container" option in legend now overwrites the container element
+   instead of just appending to it, fixing the infinite legend bug. (reported
+   by several people, fix by Brad Dewey)
+
+
+
+## Flot 0.4 ##
+
+### API changes ###
+
+Deprecated axis.noTicks in favor of just specifying the number as axis.ticks.
+So ```xaxis: { noTicks: 10 }``` becomes ```xaxis: { ticks: 10 }```.
+
+Time series support. Specify axis.mode: "time", put in Javascript timestamps
+as data, and Flot will automatically spit out sensible ticks. Take a look at
+the two new examples. The format can be customized with axis.timeformat and
+axis.monthNames, or if that fails with axis.tickFormatter.
+
+Support for colored background areas via grid.coloredAreas. Specify an array
+of { x1, y1, x2, y2 } objects or a function that returns these given
+{ xmin, xmax, ymin, ymax }.
+
+More members on the plot object (report by Chris Davies and others).
+"getData" for inspecting the assigned settings on data series (e.g. color) and
+"setData", "setupGrid" and "draw" for updating the contents without a total
+replot.
+
+The default number of ticks to aim for is now dependent on the size of the
+plot in pixels. Support for customizing tick interval sizes directly with
+axis.minTickSize and axis.tickSize.
+
+Cleaned up the automatic axis scaling algorithm and fixed how it interacts
+with ticks. Also fixed a couple of tick-related corner case bugs (one reported
+by mainstreetmark, another reported by timothytoe).
+
+The option axis.tickFormatter now takes a function with two parameters, the
+second parameter is an optional object with information about the axis. It has
+min, max, tickDecimals, tickSize.
+
+## Changes ##
+
+ - Added support for segmented lines. (based on patch from Michael MacDonald)
+
+ - Added support for ignoring null and bad values. (suggestion from Nick
+   Konidaris and joshwaihi)
+
+ - Added support for changing the border width. (thanks to joebno and safoo)
+
+ - Label colors can be changed via CSS by selecting the tickLabel class.
+
+## Bug fixes ##
+
+ - Fixed a bug in handling single-item bar series. (reported by Emil Filipov)
+
+ - Fixed erratic behaviour when interacting with the plot with IE 7. (reported
+   by Lau Bech Lauritzen).
+
+ - Prevent IE/Safari text selection when selecting stuff on the canvas.
+
+
+
+## Flot 0.3 ##
+
+This is mostly a quick-fix release because jquery.js wasn't included in the
+previous zip/tarball.
+
+## Changes ##
+
+ - Include jquery.js in the zip/tarball.
+
+ - Support clicking on the plot. Turn it on with grid: { clickable: true },
+   then you get a "plotclick" event on the graph placeholder with the position
+   in units of the plot.
+
+## Bug fixes ##
+
+ - Fixed a bug in dealing with data where min = max. (thanks to Michael
+   Messinides)
+
+
+
+## Flot 0.2 ##
+
+The API should now be fully documented.
+
+### API changes ###
+
+Moved labelMargin option to grid from x/yaxis.
+
+## Changes ##
+
+ - Added support for putting a background behind the default legend. The
+   default is the partly transparent background color. Added backgroundColor
+   and backgroundOpacity to the legend options to control this.
+
+ - The ticks options can now be a callback function that takes one parameter,
+   an object with the attributes min and max. The function should return a
+   ticks array.
+
+ - Added labelFormatter option in legend, useful for turning the legend
+   labels into links.
+
+ - Reduced the size of the code. (patch by Guy Fraser)
+
+
+
+## Flot 0.1 ##
+
+First public release.
