March / April 2019

Hello all! We have a lot to cover in this changelog, as we’ve fallen behind with updates recently. So much has happened since the last time we posted one, so we’re going to list everything here, and then certain topics we’ll cover in more detail in separate posts.

Additionally, we’ll be using a new format for changelog releases going forward. We’re deprecating the use of semantic versioning because with our multiple products that all overlap, complexity abounds. So in the interest of keeping things simple, we’ll be using named versions going forward, corresponding to the week of the year we do the current release.

We’ve decided to use mythological creatures and will have (around) 26 versions a year, which is 52 weeks / 2 = 26, which conveniently is the number of letters in the alphabet. So the next version we’ll be releasing is “Ipotane”.

Okay, here’s what’s happened in the last couple months!
