ANNOUNCEMENT: BGPlay @RIS upgraded to 1.4

[Apologies for duplicate emails]

Dear All,

The BGPlay team is pleased to announce that the BGPlay instance hosted 
by the RIPE NCC has been updated to BGPlay v1.4. Notable fixes in this 
release include:

- Depending on the exact query interval input by the user and the
   sequence of BGP updates preceding it, previous versions of BGPlay
   sometimes generated an incorrect initial AS graph. This has been
   corrected.
- If the query interval was spread over multiple days, BGPlay would
   sometimes not display all BGP updates on the last day.
- BGPlay no longer crashes when it encounters an AS-set.
- Mouse wheel scrolling has been much improved: the animation window
   no longer scrolls one pixel at a time.
- Better error handling and reporting

BGPlay is a tool to visualise BGP updates in the Routing Information 
Service (RIS) database. An animated, interactive graphical display makes 
it easier to interpret how BGP updates affect the routing of a specific 
prefix.

Please note that BGPlay requires the Java browser plug-in version 1.4 or 
above (this is available for download at http://www.java.com/en/download/ ).

BGPlay was developed by the Computer Networks Research Group at Roma Tre 
University and is hosted by the RIPE NCC, who provide direct access to 
the RIS database.
