## Whats new in Version 1.3.0 'Mimas'?

Please note that this is a release in our 'cutting edge' release series. As such it contains new features and extends the programmatic interface over QGIS 1.0.x and QGIS 1.2.0. If an unchanging user interface, programmatic API and long term support is more important to you then cool new and untested features, we recommend that you use a copy of QGIS from our Long Term Support (LTS)1.0.x release series.

This release includes over 30 bug fixes and several useful new features:

OSM plugin & provider updates:

- new OSM style files.
- new icons.
- dialog text updated and completed.
- "Saving OSM into file" functionality was improvements.
- fixed some problems with encoding... ascii to utf-8.
- all OSM layers are automatically removed after disabling OSM plugin in plugin manager.
- other OSM related bugfixes.

Other notable features and improvements in this release

- Marker size is now configurable when editing a layer.
- Incorporation of the analysis library into the mainstream release.
- Identify features across multiple layers.
- Added a new plugin for carrying out raster terrain analysis (computing slope aspect, steepness etc).
- A reshape tool to apply to line/polygon geometries. The part of a geometry between the first and last intersection of the reshape line will be replaced.
- Added snapping to current layer in measure dialog.
- Added ability to select the primary key for views.
- Zoom to a coordinate by entering it in the status bar coordinate display.

## Whats new in Version 1.2.0?

This release includes over 140 bug fixes and enhancements over the QGIS 1.1.0 release. In addition we have added the following new features:

    Editing:

    Editing functionality in QGIS has had a major update in this release. This
    includes the addition of new vector editing tools:

    - delete part of multipart feature
    - delete hole from polygon
    - simplify feature
    - Added a new "node" tool (in advanced digitizing toolbar).
    - New functionality for merging features
    - Added undo/redo functionality for vector layer editing.
    - Added option to show only markers of selected features in editing mode.
    - Change layer's icon in legend to reflext that the layer is editable.

    In addition, there are undo/redo actions in Edit menu, in Advanced digitizing toolbar
    and there is a new dock widget displaying undo stack of active layer.

    About the node tool: It resembles a tool for editing paths by nodes that is
    present in every vector editor. How does it work (in QGIS)? Click on a
    feature, its nodes will be marked by small rectangles. Clicking and dragging a
    node moves it. Double clicking a segment will add a new node. Pressing delete
    key will remove active node. It's possible to select more active nodes at
    once: by clicking and dragging a rectangle. It's possible to select a segment's
    adjacent nodes by clicking on the segment. It's possible to add/remove active
    nodes by using Ctrl when clicking a node or dragging a rectangle

    We recommend that you turn off vertex markers in QGIS options when working with
    this tool: the redraws are much faster and the map is not cluttered with
    markers.

    Keyboard shortcuts:

    New feature: configure shortcuts for actions within main window of qgis!
    See menu Setting->Configure shortcuts

    Map Composer:

    It is now possible to lock/unlock composer item positions by right mouse click.
    The width and height of the composer map will now remain fixed if user sets the
    composer map extent to the map canvas extent. possibility to display
    current date in composer label by typing (d 'June' yyyy) or similar.
    It is now possible to keep the current layers in a composer map even if further
    layers are added to the main map. Export to PDF in composer is now possible.

    Attribute tables:

    It is now possible to search the attribute table within selected records only.
    General speedups have been made on the attribute table. Setting of field width
    and precision when adding attributes is now possible. Handling of attribute
    types in WFS provider has bee improved.

    Attribute aliases for vector layers are now available. The aliases are shown
    instead of the original field names in the info tool and attribute table to
    make things easier for end users. There is now a GUI for setting edit widgets
    for layer attributes.  A new dialog allows loading a value map from a layer
    (could be non-spatial table too!).  The edit widgets settings will also now
    be respected in the attribute table.

    Plugins:

    - The order of layers in the WMS dialog can now be changed.
    - The eVis plugin, version 1.1.0, has been added to the QGIS project and
      included as a standard plugin. More information about eVis can be found here:
      http://biodiversityinformatics.amnh.org/open_source/evis/documentation.php .
    - The interpolation plugin now has the ability to use line layers as constrains
      for triangulation in interpolation plugin. You can also now save the
      triangulation to shape file.
    - An new OpenStreetMap provider and plugin have been added to QGIS.

    Projects Management:

    QGIS now includes support for  project relative position of file data sources
    and svgs. The saving of relative paths of file data sources is optional.

    PostGIS & the PostgreSQL Provider:

    You can now select the SSL mode when adding a new DB connection. Turning off
    SSL encryption can greatly improve performance of PostGIS data loading where
    connection security is not required. Support has been added for more native
    types and for setting of column comments.

    Symbology enhancements:

    - allow refresh of symbols via popup menu on the renderer's symbol selection
    - add support for data defined symbol(name)s
    - add support for font symbol markers (only data defined - no gui yet)
    - add symbol size in map units (ie. symbols that keep the size in mapunits
      independant of the mapscale)

    Command line arguments:

    Added command line argument support on windows.
    Enhancement of command line arguments:
    - allow given snapshot sizes
    - allow suppression of splash screen
    - capture map decorations from plugins on snapshots

    Grass:

    There is a new GRASS shell. Also there have been many cleanups and consistency
    updates.
