Release Notes

BurntSushi/jiff (jiff)

v0.2.14

Compare Source

===================
This release includes a smattering of bug fixes, and hopefully a small
improvement to the time it takes to compile Jiff. Also, in this release, when
TZ is set to a non-empty but invalid value, Jiff will always fall back to
Etc/Unknown when using TimeZone::system(). This differs from previous
behavior where Jiff would, in this case, attempt to read the system's default
time zone. This change brings Jiff into consistency with existing Unix tooling
like date, and is also arguably a better failure mode. That is, when TZ is
set but invalid, we shouldn't silently fall back to the default system time
zone, but instead do something that indicates something has potentially gone
wrong.

Enhancements:

• #​364:
  Jiff now falls back to Etc/Unknown for invalid TZ values.
• #​379:
  Improve compilation times.

Bug fixes:

• #​365:
  Fixes a compile error in Jiff when only the tzdb-concatenated feature was
  enabled.
• #​366:
  Fixes slow initial Zoned::now() in environments where /usr/share/zoneinfo
  is on a very slow file system (like CI environments).
• #​376:
  Avoids searching for a tzdb at /usr/share/zoneinfo on Windows.
