Changes for version 1.67
- Fixed a regression introduced in 1.60. Older versions of this library would match dates pretty match anywhere in a string, so "%Y-%m-%d" would match a string like "abcd1234-12-30efgh". This is probably _too_ permissive, but we definitely want to match on word boundaries so that we match "log.2016-03-31". Based on a PR from YASUTAKE Kiyoshi. GitHub #3.
- DateTime::Format::Strptime - Parse and format strp and strf time patterns
