Kent Overstreet publikoi versionin e sistemit t\u00eb skedar\u00ebve Bcachefs 1.38.6 dhe shpalli heqjen zyrtare t\u00eb shenj\u00ebs eksperimentale t\u00eb zhvillimit nga projekti. Kohet e fundit, numri i raporteve p\u00ebr probleme ka r\u00ebn\u00eb, dhe defektet q\u00eb zbulohen jan\u00eb b\u00ebr\u00eb m\u00eb pak t\u00eb r\u00ebnda dhe m\u00eb t\u00eb nd\u00ebrlikuara.<\/p>\n

Versioni mbulon dy paketa: bcachefs-kernel-dkms me modulin e b\u00ebrjes s\u00eb kernelit, i mbledhur me sistemin DKMS (Dynamic Kernel Module Support), dhe bcachefs-tools me utilitarin bcachefs q\u00eb ekzekutohet n\u00eb hap\u00ebsir\u00ebn e p\u00ebrdoruesit, duke realizuar komandat p\u00ebr krijimin (mkfs), montimin, rikuperimin dhe verifikimin e FS. Paketat jan\u00eb mbledhur p\u00ebr Debian, Ubuntu, Arch Linux dhe priten p\u00ebr Fedora, openSUSE dhe NixOS. Moduli DKMS mb\u00ebshtet funksionimin me kernel\u00ebt Linux, duke filluar nga 6.16.<\/p>\n

Pavar\u00ebsisht numrit t\u00eb versionit t\u00eb zakonsh\u00ebm, i caktuar nga mungesa e ndryshimeve n\u00eb formatin e diskut, l\u00ebshimi 1.38.6 p\u00ebrmban nj\u00eb s\u00ebr\u00eb optimizimesh t\u00eb r\u00ebnd\u00ebsishme t\u00eb performanc\u00ebs.

P\u00ebrve\u00e7 optimizimeve n\u00eb versionin Bcachefs 1.38.6, u realizua mb\u00ebshtetje p\u00ebr lidhjen e deri n\u00eb 255 pajisjeve n\u00eb nj\u00eb sistem t\u00eb skedar\u00ebve.

P\u00ebrve\u00e7 k\u00ebsaj, vazhdon puna p\u00ebr rishkrimin e kodit n\u00eb gjuh\u00ebn Rust.
