From the tzcode2013e release notes:

  Changes affecting Godthab time stamps after 2037 if version mismatch

    Allow POSIX-like TZ strings where the transition time's hour can
    range from -167 through 167, instead of the POSIX-required 0
    through 24.  E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the
    new Fiji rules.  This is a more-compact way to represent
    far-future time stamps for America/Godthab, America/Santiago,
    Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem,
    Pacific/Easter, and Pacific/Fiji.  Other zones are unaffected by
    this change.  (Derived from a suggestion by Arthur David Olson.)

    Allow POSIX-like TZ strings where daylight saving time is in
    effect all year.  E.g., TZ='WART4WARST,J1/0,J365/25' for Western
    Argentina Summer Time all year.  This supports a more-compact way
    to represent the 2013d data for America/Argentina/San_Luis.
    Because of the change for San Luis noted above this change does not
    affect the current data.  (Thanks to Andrew Main (Zefram) for
    suggestions that improved this change.)

    Where these two TZ changes take effect, there is a minor extension
    to the tz file format in that it allows new values for the
    embedded TZ-format string, and the tz file format version number
    has therefore been increased from 2 to 3 as a precaution.
    Version-2-based client code should continue to work as before for
    all time stamps before 2038.  Existing version-2-based client code
    (tzcode, GNU/Linux, Solaris) has been tested on version-3-format
    files, and typically works in practice even for time stamps after
    2037; the only known exception is America/Godthab.

  Changes affecting API

    Support for floating-point time_t has been removed.
    It was always dicey, and POSIX no longer requires it.
    (Thanks to Eric Blake for suggesting to the POSIX committee to
    remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy
    Heninger, Arthur David Olson, and Alois Treindl, for reporting
    bugs and elucidating some of the corners of the old floating-point
    implementation.)

    The signatures of 'offtime', 'timeoff', and 'gtime' have been
    changed back to the old practice of using 'long' to represent UT
    offsets.  This had been inadvertently and mistakenly changed to
    'int_fast32_t'.  (Thanks to Christos Zoulos.)

    The code avoids undefined behavior on integer overflow in some
    more places, including gmtime, localtime, mktime and zdump.

  Changes affecting code internals

    Minor changes pacify GCC 4.7.3 and GCC 4.8.1.

  Changes affecting documentation and commentary

    Documentation and commentary is more careful to distinguish UT in
    general from UTC in particular.  (Thanks to Steve Allen.)

From the tzcode2013f release notes:

  Changes affecting API

    The types of the global variables 'timezone' and 'altzone' (if present)
    have been changed back to 'long'.  This is required for 'timezone'
    by POSIX, and for 'altzone' by common practice, e.g., Solaris 11.
    These variables were originally 'long' in the tz code, but were
    mistakenly changed to 'time_t' in 1987; nobody reported the
    incompatibility until now.  The difference matters on x32, where
    'long' is 32 bits and 'time_t' is 64.  (Thanks to Elliott Hughes.)
