Changelog

All notable changes to this project should be documented in this file. They probably won't be, but they should.

As of v.2.8, the API of units2 should be stable enough to adopt a "no-breaking-changes" policy. You should never have any reason not to use the most recent version of units2.

2.7 - 22nd Sept 2017

Added

• This changelog. This and previous log entries will be disappointing.
• IEC binary prefixes and bit/octet units.
• Support for rational exponents in dimensional analysis (via root in Multiplicative protocol)
• ops/sqrt

Changed

• the brand slogan is now "a Clojure library for units of measurement", this improves searchability / SEO.
• ops are now (re)defined with decorator functions instead of macros to allow more generality / expose this functionality to the user.
• the name of the standard units library is now units2.stdlib instead of the historical *.astro.
• the preferred name for unit-from-powers is now parse-unit, though the old name is still provided.
• the way modular arithmetic with units is done in ceil, floor, round, has improved.
• units2 no longer provides wrapped versions of the SI/NonSI units defined by org.jscience, instead defining units from scratch.

Removed

• A dynamic boolean allowing unsafe, surprising behaviour was removed. Unsurprising behaviour is now mandatory rather than default. Removed for sanity.
• units2 no longer depends on incanter/apache for calculus. If the naive builtins aren't good enough, users probably want to decorate their own functions anyway. Removed to prevent feature creep and unnecessary dependency on other libraries.

[2.6] - 17th Feb 2017

Added

• from added to core interfaces.
• various experimental interactions with clojures' specs.

Changed

• calculus is now (re)defined with decorator functions to allow more generality.
