End Date of the Review Period

Reviews run for a minimum of one week. The outcome of the review is decided on this date. This is the last day to make comments or ask questions about this review.




This release removes all deprecated API and lifts the project into the phase of maturity.

Architectural Issues

Eclipse Sprotty has a solid working code with stable APIs:

  • We have used the pre-1.0.0 versions to implement changes according to experience gathered with using the framework in real-world projects.
  • All changes are documented in the CHANGELOGs and deprecated API have been marked as such.
  • The accumulated deprecated API is being removed prior to the 1.0.0 release (#374) in order to get to a clean state; the goal is to keep the API as stable as possible once the project is declared mature.
  • Eclipse GLSP builds on top of Sprotty and has already graduated from its incubation phase.
  • Sprotty is being used successfully by several companies from various industrial branches; the framework is known to work reliably and to deliver high-quality graphical views.
