Understanding Adobe Illustrator 2021 (v25.3.1.390): Features, Security, and Best Practices
The version number 25.3.1.390 is not arbitrary. It marks a crucial update in Illustrator's history. Historically, Illustrator, like many other Adobe apps, ran on Intel-based Macs using a compatibility layer called Rosetta 2 when the first M1 Macs arrived. This worked but didn't unlock the chip's full potential.
Version 25.3.1 changed that. It was one of the first Illustrator versions to offer . For designers, this meant the software could finally leverage the full power of the M1 architecture. The results were dramatic: complex vector file scrolling performance improved by up to 390%, file opening speeds increased by 119%, and overall responsiveness was roughly 65% faster compared to running on an Intel Mac. This made working on massive, intricate projects smoother and more efficient than ever before. The .390 likely refers to an internal build number, but the core of this release is the fundamental performance leap for Mac users.
Minimum 8GB required; 16GB of RAM is highly recommended for managing complex artboards and large vector assets.
