Mwepụta nke obere ngwa ngwa sistemụ BusyBox 1.31

Ewebata ngwugwu ntọhapụ Igbe ọrụ 1.31 na mmejuputa usoro ihe eji arụ ọrụ UNIX ọkọlọtọ, nke emebere dị ka otu faịlụ nwere ike ime ma kachasị mma maka obere oriri nke akụrụngwa sistemụ yana nha nha nke na-erughị 1 MB. Ntọhapụ mbụ nke alaka ọhụrụ 1.31 ka edobere dị ka onye na-adịghị akwụsi ike, a ga-enye nkwụsi ike zuru oke na ụdị 1.31.1, nke a na-atụ anya n'ihe dị ka otu ọnwa.

Ihe ngwungwu a nwere onwe ya mgbe ejiri uclibc wuo ya, iji mepụta sistemu arụ ọrụ n'elu Linux kernel, naanị ihe ị ga-eme bụ imepụta faịlụ ngwaọrụ dị na ndekọ / dev wee dozie faịlụ nhazi. E jiri ya tụnyere 1.30 ntọhapụ gara aga, oriri RAM nke mgbakọ BusyBox 1.31 na-ahụkarị belatara site na 86 bytes (site na 1008478 ruo 1008392 bytes).

BusyBox bụ ngwá ọrụ bụ isi n'ọgụ megide mmebi GPL na ngwa ngwa.
