 ### Interact with Eclipse Foundation for new splash screen series
 
 **When:** after the March release
 
-Although, Eclipse IDE packages are shipped every 3 months, one release a year (usually in June) receives addition marketing support. This usually include a new main website and a new splashscreen. The Community must request the new splashscreen as early as possible before June (ideally after the March release) via a Bugzilla ticket addressed to Eclipse Foundation. If you open this ticket, make sure Eclipse Foundation marketing people are registered as CC.

 When ready, the Eclipse Foundation marketing team will submit some splashscreen, sometimes asking for feedback when multiple splash screens are competing. When the final splashscreen is selected, the community has to ask for the variations of this splashscreen: some saying just "Eclipse" (for the Platform artifacts) and some saying "Eclipse IDE" (for the EPP packages), and the 4 variations for each quarterly release (202x-06, 202x-09, 202x-12, 202(x+1)-03).
