DFLib 1.0 release candidate 2 #395

DFLib 1.0.0-RC2 was just posted. It is a drop-in replacement for RC1 and fixes a number of bugs (mostly related to various edge conditions around Series operation). Planning to release a GA some time mid-December.

Since the point of RC2 is stability, there's intentionally nothing new and exciting in it, but elsewhere in DFLib great things are cooking....

• The upcoming 1.1.0 release will feature support for "float" primitive Series and expressions (saving memory on many tasks), Exp.shift(), ECharts itemStyle element for all types of charts, as well as other chart styling options.
• And in 2.0.0, we separated Series and aggregating expressions evaluation paths (making the expression API shorter, more clear and precise), added aggregating functions to date and time expressions, added arbitrary percentile calculation expressions (previously existing median() is a special case of the new quartile(double)), working on a String grammar for expressions (still in progress), added even more chart customization options, and finally, implemented saving charts to HTML.
• We have a new logo and gradually updating the website.

On the last point, it seems to be a law of nature, that any data processing technology inevitably evolves into producing dashboard-generating code. And we are no exception of course 😀
