A new version of TZDB has been release (1.8.121113). This version adds some very small changes. The biggest update is the bundled database version.
TZDB is an open source project that provides Delphi (7+) and FreePascal (2.0+) users with a “built-in” timezone database. The same source of data is used in most Unixes, Java, MacOS and multiple other projects out there.
