Google has started rolling out a software update for Googlebooks that frees between 3GB and 6GB of RAM, cuts Chrome crashes and fixes roughly 60 Android security flaws, according to a report by Android Central. The news was first surfaced by Techmeme, which flagged the release as one of the day's biggest stories for Android and ChromeOS users.
The headline number is the memory gain. Google says the freed RAM comes from on-device AI optimizations that clean up how the system uses memory, rather than from any hardware change. On a machine with 8GB of RAM, getting 3GB back is a meaningful jump in what you can keep open at once.
Googlebook update frees 3GB-6GB of RAM
The RAM savings are the result of on-device AI optimizations, per Android Central's report. These run locally on the device rather than in the cloud, which means the gains should apply without an internet connection and without sending usage data off the machine.
The exact amount freed depends on the device and how it is being used, which is why Google gives a range of 3GB to 6GB rather than a single figure. Devices with more memory in use are likely to see the larger end of that range, while lighter setups may see less.
Roughly 60 Android security patches
Alongside the memory work, the update bundles about 60 Android security patches. That is a substantial batch, and it makes the release as much a security fix as a performance one.
Google has not published the full breakdown of what each patch addresses in the material available here, so we are not going to speculate about specific vulnerabilities. What is clear is that the volume of fixes is high enough that delaying the update carries some risk.
Fewer Chrome crashes
The third pillar of the release is stability: Google says the update reduces Chrome crashes. Chrome is the default browser on Googlebooks and, for many users, the main thing the machine is running all day, so crash fixes show up quickly in daily use.
Combined with the RAM savings, the effect should be a browser that stutters less when many tabs are open and recovers less often from a sudden close.
What it means for you
If you own a Googlebook or another ChromeOS device, this is an update worth installing as soon as it reaches you. It is a free performance and security upgrade: more usable memory, fewer browser crashes and a large set of Android patches.
