Full Changelog: 4.0.0...4.0.1

Version 4.0.0: More precise time scale conversions, human readable serialization of durations, and lots more

This update is not merely an iteration, but a redesign in how time scale are handled in hifitime, fixing nanosecond rounding errors, and improving the Python user experience. Refer to the blog post for details. As of version 4.0.0, Hifitime is licensed under the Mozilla Public License version 2, refer to discussion #274 for details.

Breaking changes

• Refactor epoch to keep time in its own time scale by @gwbres and @ChristopherRabotin in #280
• Duration serde now human readable + Display of Epoch is now Gregorian in its initialization time scale by @ChristopherRabotin in #299
• Improve error handling (switching to snafu) by @ChristopherRabotin in #300
• Breaking change: renamed Julian date constants and removed other Julian date constants by @ChristopherRabotin in #307
• Minimum Support Rust Version (MSRV) bumped to 1.77.0

Note: as of version 4.0.0, dependency updates will increment the minor version.

New features / improvements

• Support exceptions in Python by @ChristopherRabotin in #301
• Add Python regression test for #249 by @ChristopherRabotin in #305
• MJD/JDE UTC fix + to_time_scale now available in Python by @ChristopherRabotin in #332
• Add Python datetime interop by @ChristopherRabotin in #333
• Add autogenerated Kani harnesses by @cvick32 in #316
• Kani autogen follow on by @ChristopherRabotin in #318

Bug fixes

• Fix bug in to_gregorian_str by @ChristopherRabotin in #308
• Fix conversion to Gregorian by @ChristopherRabotin in #303
• Rename EpochError to HifitimeError and add exception testing by @ChristopherRabotin in #315
• Prevent rounding of the GNSS from nanoseconds initializers by @ChristopherRabotin in #319
• Fix ceil with zero duration by @cardigan1008 in #323
• Fix token exceed in from_str() by @cardigan1008 in #324

The main change in this refactoring is that Epochs now keep the time in their own time scales. This greatly simplifies conversion between time scales, and ensures that all computations happen in the same time scale as the initialization time scale, then no sub-nanosecond rounding error could be introduced.

4.0.0-alpha: Hifitime rewrite

Version 4.0.0-alpha

The main change in this refactoring is that Epochs now keep the time in their own time scales. This greatly simplifies conversion between time scales, and ensures that all computations happen in the same time scale as the initialization time scale, then no sub-nanosecond rounding error could be introduced.

Full Changelog: 3.10.0...4.0.0-alpha

4.0.0-dev0: Add QZSS time scale -- possibly a breaking change (essentially 3.10.0)

What's next?

This is probably the last release of version 3.x. There's a fair amount of small bugs here and there in 3.x, and these aren't trivial to fix. The architecture changes introduced by @gwbres and I for the development of 4.x should fix all of those in one go.

Also, version 4.0 will likely switch to the Mozilla Public License from Apache 2: if you have concerns about this, please head over to #274 to voice them. From the user point of view, there should be absolutely no change, even if you're selling code that uses an unmodified version of Hifitime.

Naming error

This release is published as 4.0.0-dev on crates.io and 4.0.0.dev0 on PyPi. This was a mistake. It should have been 3.10.0. That's probably for the better though since it introduces one breaking change. Version 4.0.0 will introduce several breaking changes and a new architecture.

• Update 4.0.0-dev to latest master by @ChristopherRabotin in #243

Notice for 3.x

With a bit of luck, this will be the last release of 3.x as version 4 makes its way to production. Version 4 will bring more consistency in time scale handling by not converting everything to TAI, but using the initialization time scale whenever possible. Follow the progress on https://github.com/nyx-space/hifitime/milestone/14 and don't hesitate to propose features or contribute. Thanks
