		| Abstract: | 
		On behalf of the GDL team, we announce the 0.9.9 release of GDL, the
 GNU Data Language. GDL is a free and open-source drop-in replacement
 for IDL, the Interactive Data Language, which has served the
 astronomical community for many years.  This release comes 15 years
 after Marc Schellens first made GDL public, and it marks several
 milestones attesting to the maturity of the project. Among these are
 updates to the plotting functionalities, major advances in the Windows
 implementation, a native support for IDL save files, and performance
 improvements.
  
 The presentation will summarize current availability of packaged
 versions of GDL, compatibility with popular IDL-written
 astronomy-related software, potential directions for the upcoming
 releases, and the key areas where GDL could benefit from further user
 feedback and new contributions. |
