Literal

・Text-data [gen-の] typos-omissions [obj-を] correction.

A changelog/patch-note entry. The leading 中点 (・) is a bullet marker common in Japanese lists. 誤字脱字 is a compact four-character compound: 誤字 ('wrong character, typo') + 脱字 ('dropped character, omission'). 修正 ('correction, amendment') ends the sentence as a nominal — a common changelog style where the sentence stays in noun form rather than resolving to a verb.
