I have finally managed to get some free time on my hands and released the latest update to TZDB containing the latest DB (from 14 March). As usual, no code changes, just data updates.
For those unaware: 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.
