Okteta, a simple editor for the raw data of files, has been released in version 0.26.0. The 0.26 series mainly brings a clean-up of the public API of the provided shared libraries. The UI & features of the Okteta program have been kept stable, next to one added new feature: there is now a context menu in the byte array viewer/editor available.
Since the port to Qt5 & KF5 Okteta has not seen work on new features. Instead some rework of the internal architecture has been started, and is still on-going.
Though this release there is a small feature added again, and thus the chance to pick up on the good tradition of the series of all-new-features-in-a-picture, like done for 0.9, 0.7, 0.4, 0.3, and 0.2. See in one quick glance what is new since 0.9 (sic):

I think it would be awesome to add support for Kaitai Struct to Okteta:

Agreed. I have collected in my notes a few generic format description languages… if only there was not that other stuff on the life TODO list… At least abstracted support for data interpreters is one thing I try to include in the big rewrite.
