\u00cbsht\u00eb n\u00eb dispozicion versioni alfa i gjuh\u00ebs s\u00eb programimit Python 3.13.0a6, i cili shquhet p\u00ebr p\u00ebrfshirjen e tij n\u00eb deg\u00ebn 3.13, mbi t\u00eb cil\u00ebn po formohet versioni stabil i Python 3.14, implementimi eksperimental i JIT-kompiluesit, i cili lejon nj\u00eb rritje t\u00eb konsiderueshme t\u00eb performanc\u00ebs.
