Spolo\u010dnos\u0165 Microsoft predstavila<\/a><\/noindex> na prebiehaj\u00facej konferencii Microsoft Build 2019 bola predstaven\u00e1 aktualizovan\u00e1 verzia podsystemu WSL2 (Windows Subsystem for Linux), ur\u010den\u00e9ho na sp\u00fa\u0161\u0165anie spustite\u013en\u00fdch s\u00faborov Linux na Windows.

Testovacia verzia WSL2 bude pon\u00faknut\u00e1 na konci j\u00fana v experiment\u00e1lnych zostav\u00e1ch Windows Insider<\/a><\/noindex>.

V r\u00e1mci WSL2 pre Windows 10 sa pon\u00fakne komponent so \u0161tandardn\u00fdm jadrom Linux 4.19. Ako bud\u00fa vych\u00e1dza\u0165 opravy pre LTS vetvu 4.19, jadro pre WSL2 bude pravidelne aktualizovan\u00e9 prostredn\u00edctvom mechanizmu Windows Update a testovan\u00e9 v infra\u0161trukt\u00fare kontinu\u00e1lnej integr\u00e1cie Microsoftu.
