Whether the wounds from the Exodus were still too fresh at the time or because some people have no sense of cultural history, some board members couldn't look at the original design's haircut without screeching "SJW". They harshly rejected the original design and proved unwilling to budge. Other designs were suggested to appease both supporters and detractors, but only one enjoyed some modicum of success.
The other /cyber/-tan's design is a lot more subdued. A simple black haircut, no (visible) augmentations or implants, and regular clothes and headphones with cool colours. Overall the design draws more inspiration from cypherpunk, where privacy and anonimity are more stressed than in the loud and openly countercultural cyberpunk. At the base level however, there are still similarities to the original /cyber/-tan's design. She's still a caucasian woman, still smokes her e-cigarette, and her limbs are cybernetic and may or may not be detachable. It's even speculated she might have extra port holes for up to 6 arm attachments.
This /cyber/-tan however doesn't use her enhancements to fight physically. She's envisioned more as a runner. Whether an edgerunner (parkouring her way through the city to relay messages) or a netrunner (combining virtual reality with hacking to steal company secrets) is a matter of personal headcanon preference.
At the moment, various factions of /cyber/ (the board) are still in a Cold War-esque stalemate in regards to which is the "official" board-tan. People are free to choose either, both, invent a third, abolish the concept altogether, or even claim the original /cyber/-tan is how cypherpunk!/cyber/-tan chooses to represent herself in cyberspace.
