Full Changelog: v3.0.1...v3.0.2

Version 3.0.1

Scoop up miscellaneous bug fixes over the past year.

Version 3

This will likely be the final release of this library. From here you should migrate to C++20 as vendors begin to ship this library under namespace std::chrono.

The master branch will continue to be bug fixed as bugs arise. However a subsequent release may or may not happen.

The CMake support of this library is chaotic (to be kind). Personally I don't use it and instead follow the installation instructions found here: https://howardhinnant.github.io/date/tz.html#Installation (needed only for tz.h).

Version 2.4.1

• Improved CMake support.
• New names for months: January
• New names for weekdays: Sunday
• Parsing with %Ez now supports optional minutes field.
• Miscellaneous bug fixes.

Version 2.4

• Introduce CMake support.
• Introduce clock_cast for converting between time_points of different clocks.
• Allow conversion between zoned_time<Duration1, TimeZonePtr1> and zoned_time<Duration2, TimeZonePtr2>.
• Miscellaneous porting and warning fixes.
• Update to latest IANA website changes.

Version 2.3

• Change directory structure to have include/ and src/.
• Rename TZ_DB to tzdb (there's a backwards compatible typedef that may disappear in the future).
• Specify constructors for nonexistent_local_time and ambiguous_local_time. This enables custom time zones to easily use them if needed.
• Support multiple versions of the IANA database. The singleton is now a lock-free thread safe singly-linked list. The existing API implicitly references the front of this list.
• Support custom time zones in zoned_time. See the Examples section in the tz documentation.
• Add C++17 deduction guide support.
• Give zoned_time a default constructor.
• Give weekday_indexed a default constructor.
• Add is_clock trait.
• Add ONLY_C_LOCALE. Helps with systems with missing time_get/time_put facets.
• Improve sub-picosecond support.
• Minor bug and compatibility fixes.

Version 2.2

• Rewrite of format and parse:
  • Many more types can be formatted and parsed with format and parse now.
    • durations, calendar types, tai_time, gps_time, ...
  • parse supports width parameter on many format flags.
  • to_stream and from_stream now return a reference to their streams.
  • Parsing whitespace very customizable with use of %n, %t and whitespace.
• Using the OS-supplied timezone database now an option on Linux and macOS.
• The downloaded timezone database install location can now be set at run time.
• Improved support for basic_string with custom allocator.
• duration I/O is merged into date.h.
• Make zoned_time and time_of_day "deduction guide ready" for C++17.
  • This eliminates the need for make_zoned and make_time in C++17.
• Many miscellaneous bug fixes.

Version 2.1

• Set USE_SHELL_API to default to 1. This better supports
  different flavors of linux.
• INSTALL can now be configured on the command line.
• Parsing and formatting fractional seconds can now handle
  super-second durations such as microfortnights.
• Formatting and parsing rewritten, moved into date.h.
• iOS support added.
• Added trivial default constructors for most calendar
  types.
• Add unary operators + and - to year.
• Add to_stream.
• Miscellaneous bug fixes.
