v1.0.0 2022-02-16 La Forclaz

Change the js_of_ocaml strategy for Ptime_clock's JavaScript implementation. Primitives of ptime.clock.os are now implemented in pure JavaScript and linked by js_of_ocaml. This means that the ptime.clock.jsoo library no longer exists, simply link against ptime.clock.os instead. Thanks to Hugo Heuzard for suggesting and implementing this.
Require OCaml >= 4.08
Correct a potential overflow in Ptime.Span.of_float_s (#26).

v0.8.6 2021-11-28 Zagreb

Require OCaml >= 4.03
Drop dependency on result compatibility package.
Alter install structure. ptime/{os,jsoo} are now installed in ptime/clock/{os,jsoo}. Also a ptime_clock.cm[t]i is now installed in ptime/clock/. The ocamlfind packages are unchanged except for ptime.clock.os.top which no longer exists.
Handle Pervasives deprecation.
Fix Ptime.truncate to always truncate down. Thanks to David Kaloper Meršinjak for the report & fix.
Allow compiling with MSVC compiler. Thanks to Jonah Beckford for the patch.

Ptime_clock: Windows support. Thanks to IndiscriminateCoding and David Allsopp for the contribution.
Fix Ptime.frac_s on pre-epoch time stamps. The function computed a span of 1s - f instead of f on these. This function is not used internally so this only affects users of this function that apply it on pre-epoch time stamps (#12). Thanks to David Kaloper Meršinjak for the report.

Add ?tz_offset_s optional argument to Ptime.weekday. Thanks to Maxence Guesdon for suggesting.

Add Ptime.v and Ptime.Span.v to safely deal with trusted inputs. Thanks to Matt Gray for suggesting.
Add Ptime.weekday, to help conversions to denormalized timestamp formats. Thanks to Romain Calascibetta for suggesting.
Build depend on topkg.
Relicense from BSD3 to ISC.
