If selected, then the images output by composer will include only
the area of the composition with content. There's also an option
for margins to add around the item bounds if required.
If the composition includes a single page, then the output will
be sized to include EVERYTHING on the composition. If it's a
multi-page composition, then each page will be cropped to only
include the area of that page with items.
A new image export options dialog has been added to facilitate
this, which also includes handy shortcuts for overriding the
print resolution or exported image dimensions.

Allows composer map grid annotations in custom formats which are
evaluated using QgsExpressions. Made possible through the use
of Expression Contexts(tm)!
for attribute tables
This allows users to set differing colors for alternating rows and
columns, first/last row/column and header row. Fixes#5131.

Previously multi-line text would overflow onto neighbouring cells.
Now rows will be expanded to fit required height of text.
Fix#10273.

Adds new data defined control for the map layers to show in a
composer map. Expression result should be a | delimited list of
layer names which will be shown in the map.

Previously map was being redrawn every time a layer was added or
removed from the registry, which blocked the ui until the map
redraw is complete.
Now the map will only be redrawn as a result of layer changes
if it's set to Render mode.
Possible fix for 12234 and 12125. (refs #12234, #12125)
There is a new check box that allows the user to tell whether a map should
keep the layer styles (it will store the state when the check box is checked).
The stored layer styles keep a snapshot of each layer's configuration
instead of just keeping name of the style.
This solves issues with styles and visibility presets in composer which were
not completely compatible.
This code has been funded by Tuscany Region (Italy) - SITA (CIG: 6002233F59)
and commissioned to Gis3W s.a.s.
When layer set is locked in composer map, also the styles associated with layers are kept.
As a result, a composition can contain maps of the same layer just with different styles.
Map settings and map renderer jobs have been improved to support temporary override of layer's style.
It is possible to pass to map settings which layers should have overridden style and map jobs
will temporarily replace the style (just for the rendering).
This change adds a new descending vertical direction mode for
map grid annotations. Previously only ascending text was
supported for vertical annotations.
Previously, for rotated maps or reprojected grids, the composer would
draw all coordinates for every map side. This resulted in a mix of
latitude/y and longitude/x coordinates showing on a side. This change
allows users to control whether they want all coordinates, latitude
only or longitude only for each map frame side. Similar options have
also been added for controlling how a map grid frame is divided.
In related news... the composer map dialog is now the ugliest,
most cluttered and un-user friendly dialog in all of QGIS. I'd
love suggestions/mockups from the UX team for ways this could
be improved.
