Ngemva kwezinsuku ezingu-40 zokuthuthukiswa, inguqulo entsha yolimi lokuhlela olubhalwe ngezibalo V (vlang) isishicilelwe. Imigomo eyinhloko ekudaleni i-V kube lula ukufunda nokusebenzisa, ukufundeka okuphezulu, ukuhlanganiswa okusheshayo, ukuphepha okuthuthukisiwe, ukuthuthukiswa okuphumelelayo, ukusetshenziswa kwenkundla ehlukahlukene, ukusebenzisana okuthuthukisiwe nolimi C, ukuphatha amaphutha okungcono, amakhono esimanje, nezinhlelo ezigcinekayo. Ikhodi yokuhlanganisa, imitapo yolwazi namathuluzi ahlobene avulwe ngaphansi kwelayisensi ye-MIT.

- Lungisa indlela yokwengeza yezinhla ezifanayo.
- Ihlola iphutha ekusetshenzisweni kwesixhumi esibonakalayo esiyimfihlo senye imojuli.
- Ukuhlola okulungisiwe kwe-negative cap kanye namanani elensi lapho kuqaliswa amalungu afanayo.
- Ukuguqula isexwayiso mayelana neduplicate yamagama emojula ye-var kanye ne-param kube iphutha.
