A method of comparing version strings in a computing environment for use in version-specific computing tasks. In one embodiment, the method divides each of a first and a second version string at each one of a set of predetermined delimiters to produce respective first and second sets of sequentially ordered string chunks. Next, string chunks of the same order from the first and second chunk sets are iteratively compared to determine matching of same-order string chunks, with the comparison continuing until a non-matching same-order string chunk pair is encountered. From the matching/non-matching comparisons, a determination may be made whether a specified quality relationship exists between the first and second version strings, where the quality relationship determines the propriety of a version-specific computing task.
