Howdy, the main feature in ELSE is the ability to set exponential curves in the [envgen~] object. I'm really proud of this as this makes this object the most versatile and complete envelope generator for Pd by far. There's basically nothing missing I can think of (except maybe add multiple sustain points eventually). The [function~] object can also generate exponential curves, in the same way as [envgen~], and this is cool to draw some crazy waveforms.
The [dir] object has suffered a major overhaul (with breaking changes) and includes new features. I'm also pretty proud of this one as it really makes it easy opening, browsing and managing files in a directory. This has always given me quite a headache and I think I finally nailed it. The last highlights is that [sort] can now sort symbols, and there are 3 new objects to manage lists ([sum], [slice] and [stream]). More details at https://github.com/porres/pd-else/releases/tag/v1.0-beta22 Almost all binaries are available there and in a few hours this will be available via deken so you can download directly from Pd.
My tutorial was also updated to reflect some of these updates, more details at https://github.com/porres/Live-Electronic-Music-Tutorial/releases/tag/v1.0-b...
