Open CASCADE 4.0 dev 1 development version Info.

Hello,

Is it possible to get the details of various features added in "Open CASCADE 4.0 dev 1 development version" ? Only limited info like "Enhancements in Boolean Operations (Phase 1)" and "Improvements (about 30 integrations)" are available. Similarly Open Cascade Document downloads also discuss 3.0 version, I believe. Details of the above summary are requested.

With best regards and thanks in advance,

Balasubramanian, P.
