ChangeLog

1.7.10
Frontend:
  * Weathermap lines now deal with bit/byte values provided by Check_MKs
    interface checks
  * FIX: Fixed "TypeError: oLabel is null" on at least geomaps
  * FIX: Fixed shape image displaying when using external URLS
  * FIX: Hiding	"Edit Map" link for "on demand" automaps
  * FIX: Fixed "modify view" dialog for "on demand" automaps
  * FIX: Fixed wrong viewport html header (Thanks to Carl Helmertz <chelmertz@op5.com>)

Automap:
  * Labels have now a white background to improve the text readability
  * Labels should not overlap on automaps with many hosts anymore
  * Slightly layout improvement of automaps in undirected mode
  * FIX: Rendering lines on zoomed automaps correctly
  * FIX: Fixed positions of labels on zoomed automaps

1.7.9
Core:
  * Livestatus: Fixed handling of hosts/services without custom variables
  * Added option to perform privilege switch to a user with less permissions
    for viewing maps in the context of this user
  * FIX: Fixed state weight definition parsing
  * FIX: Fixed demo automap (missing programStart method in demo backend)

Frontend:
  * FIX: Not adding textboxes to "to be updated list" anymore; This might have
    lead to objects not being reloaded on maps with many texboxes
  * FIX: More robust handling of broken/no perfdata handling in weathermap
         lines of type -->BW+%-><-BW+%--

1.7.8
Automap:
  * FIX: Added missing program restarted check to invalidate chaches

Geomap:
  * FIX: Not providing auth credentials in http requests to proxy when none set

Frontend:
  * FIX: Fixed "Undefined index" error when changing backend_id of maps
  * FIX: Fixed hiding of shapes during refresh (enable_refresh=1)
  * Reverted change from 1.7.5 (Weathermap lines with byte/bit values in 
    labels should print human) which broke the handling for some plugins

1.7.7
Core:
  * Implemented "on demand" maps. Maps which only need a basic configuration
    of global parameters like automaps and geomaps can now be configured and 
    created on demand by URL parameters. This mode is reached by simply
    calling the map URL without "show=" parameter and a bunch of parameters
    for the global section of the map instead.
  * Implemented center and bottom as label coordinate values which are
    automatically calculated depending on the rendered sizes

Automap:
  * Changed default behaviour of the automap concerning the root host. By
    default NagVis uses a virtual root node which represents the monitoring
    core. It adds the parent tree and all nodes which have no parents defined
    below this node. If no parents are configured, all hosts are rendered
    below this virtual root node.

1.7.6
Core:
  * Improved main configuration parsing code (should not mixup comments
    and empty lines anymore)
  * Added shinken business_impact filter to automaps (set shinken_features=1
    in [global] section in main configuration to enable this feature)
    Thanks to Thibault Cohen for the patch)

Frontend:
  * Added support for custom context menu actions like connecting via
    SSH, RDP, HTTP, ... to the monitored hosts.
  * FIX: Removed debug output while recalculating bandwidth of weathermap lines
  * FIX: Fixed height of iframes in Container objects

1.7.5
Core:
  * Allowing rgba(255,255,255,0.6) like definitions in e.g. label_style
  attributes in map configuration files

Frontend:
  * Hiding all kind of javascript error messages automatically on next
    successful processing
  * IE below 9: Fixed invisible lines (z-index was not set)
  * Weathermap lines with byte/bit values in labels should print human
    readable traffic now

Automap:
  * Reimplemented ignore_hosts parameter (Thanks to Thibault Cohen)

1.7.4
Core:
  * Extended logon module CoreLogonMultisite to support the
    new cookie format of Check_MK 1.2.1i2 and newer

Frontend:
  * Hiding HTTP status error messages automatically on next successful request

  * Bugfix: Fixed background positioning on browser zoomed maps
  * Bugfix: Fixed javascript error when rotations are disabled
  * Bugfix: Multisite module is catching single map errors now and show all
    maps in the list regardless of the error. Maps with errors will be listed
    as UNKNOWN (orange) in the multisite snapin

Geomap:
  * New option source_type to configure a csv file or the used backend as
    datasource. In backend mode, the backend used on the map must support
    the new geomap functions (currently only livestatus backend). All hosts
    to be shown need the custom variables _LAT and _LONG. The hosts can
    optionally be filtered by hostgroups

    problems with multiple geomaps

  * Cleaned up session auth code (Moved session module code to auth handler)
  * Bugfix: The installer overwrites the default iconset files on upgrade as expected
  * Added mechanism to search userfiles in independent structures. This allows
    usage of the local/ structure in OMD
  * Bugfix: Fixed section merging in main config when using more than one config file
  * Using configured permissions on uploaded files (backgrounds, shapes, maps) now

  html mode assumes that the gadget does not render images as classic gadgets
  but renders HTML code

    just care about the paths - should be more robust

    available

    You can now "lock/unlock" all objects for editing using the "Edit Map" menu.
  * Added new sidebar for better navigation. It can be opened by clicking on
    the "Open" label in the header menu. The state of the sidebar and the
    single nodes is stored in user specific profile files
  * Added new parameter {parent_map} to map/automap global sections which is
    used in header/sidebar menus to draw a map hierarchy
  * Colors and ranges of weathermap lines are now customizable using the
    object configuration option line_weather_colors
  * Fixed wrong label for MBit/s in weathermap bandwidth display

    necessary permissions)
