Or g ▁Server ▁version ▁ 6 . 8 . 0 . ▁ ▁The ▁extension ▁implements ▁a ▁collection ▁of ▁un related ▁add itions ▁to ▁the ▁protocol . ▁ ▁The ▁theme ▁of ▁the ▁collection ▁is ▁small ▁add itions ▁to ▁remove ▁important ▁defect s ▁in ▁the ▁protocol ▁that ▁can ' t ▁be ▁worked ▁around ▁using ▁the ▁pure ▁X 1 1 ▁protocol . ▁ ▁The ▁point ▁of ▁implementing ▁these ▁add itions ▁in ▁an ▁extension ▁is ▁to ▁leave ▁the ▁core ▁server ▁code , ▁and ▁a ▁server ▁that ▁does ▁not ▁include ▁the ▁X F ix es ▁extension , ▁implementing ▁the ▁original ▁pure ▁X 1 1 ▁protocol . ▁ ▁However , ▁as ▁the ▁add itions ▁are ▁designed ▁in ▁a ▁back ward ▁compatible ▁way , ▁there ▁is ▁no ▁practical ▁reason ▁for ▁a ▁server ▁not ▁to ▁implement ▁them . ▁ ▁The ▁client ▁and ▁server ▁can ▁always ▁negoti ate ▁down ▁to ▁the ▁add itions ▁that ▁both ▁understand . ▁ ▁Version ▁ 1 ▁of
