Adobe Flash Professional: Cs5.5 -thethingy-
You could now draw a cartoon in Flash, write some ActionScript, and compile it directly into a native iPhone app. Not a browser plugin. An actual, App Store-ready .ipa file.
So what did Adobe do? They doubled down on the one thingy no one expected.
Released in April 2011, CS5.5 didn’t roar onto the scene. It sidled in. It was neither the revolutionary breakthrough of CS3 (the first Intel Mac version) nor the final death rattle of CS6. Instead, CS5.5 was a patch . A pivot. A desperate, brilliant, and ultimately futile attempt to keep the Flash dream alive while the iPhone sailed the world without it.
Whisper it in the comments. Your secret is safe. The SWF format is dead. Long live thethingy.
Was it perfect? No. Performance was janky. Memory leaks were common. But for a bedroom coder in 2011, it felt like alchemy. You could draw a button, click "Test Movie," and suddenly it was vibrating on a Retina display.
In the pantheon of creative software, few tools have inspired as much love, frustration, and nostalgic reverence as Adobe Flash. And within that lineage, one version stands alone as the awkward, slightly-overqualified middle child: Flash Professional CS5.5 (the “thethingy” edition, as the elders call it).
But its true legacy is in the mindset . CS5.5 was the last version of Flash that felt like a toy —a powerful, broken, beautiful toy. After CS6, Adobe handed the keys to Animate CC, which is technically superior but emotionally sterile.
That was thethingy —the impossible promise of "write once, run on Steve’s walled garden." Open CS5.1 today, and you’ll squint. The interface was a mess of gradients, bevels, and glossy panels. The timeline was still a linear horror show of layer folders and keyframes. The Properties panel changed context so often you’d get whiplash.
So here’s to you, Adobe Flash Professional CS5.5. You were the middle child no one asked for. You were the bridge between the wild west of the Flash web and the sterile prison of the App Store. And you were, without a doubt, thethingy .
