It also had some bugs and infelicities caught by further testing, and 
fixed in the attached patches. At this point it's good enough to be put 
into the main experimental version on GitHub, so you can pick up the 
fully-patched version there <https://github.com/eggert/tz>.

The new file tzdata.zi is currently 123,621 bytes of text data, which 
shrinks to 22,254 bytes when compressed via 'lzip -9'. This is a 
significant saving over the 669,396 (compressing to 227,548) bytes in 
the traditional data source files, or the 460,823 (compressing to 
196,210) bytes in the installed binary data files.
