Saki 19.3.0 na injin kama-da-wane na GraalVM da aiwatar da Python, JavaScript, Ruby da R dangane da shi.

Kamfanin Oracle aka buga saki na'urar kama-da-wane ta duniya GraalVM 19.3.0, wanda ke goyan bayan aikace-aikacen da ke gudana a cikin JavaScript (Node.js), Python, Ruby, R, kowane yarukan JVM (Java, Scala, Clojure, Kotlin) da harsuna waɗanda LLVM bitcode za a iya samarwa (C, C ++). , Tsatsa). An rarraba reshen 19.3 azaman Tallafin Dogon Lokaci (LTS) sakin da na ban mamaki tallafi JDK11, gami da ikon tattara lambar Java cikin fayilolin aiwatarwa (Hoton Native GraalVM). Lambar aikin rarraba ta mai lasisi a ƙarƙashin GPLv2. A lokaci guda, an fitar da sabbin nau'ikan Python, JavaScript, Ruby da aiwatar da yaren R ta amfani da GraalVM - GraalPython, GraalJS, TruffleRuby и FastR.
