Google has released new Algorithm update for its Google Play Store app. The new Delta Bsdiff Algorithm will reduce the app update size. This will reduce the data required to install the app update.
Google in a post said:
For approximately 98% of app updates from the Play Store, only changes (deltas) to APK files are downloaded and merged with the existing files, reducing the size of updates. We recently rolled out a delta algorithm, bsdiff, that further reduces patches by up to 50% or more compared to the previous algorithm. Bsdiff is specifically targeted to produce more efficient deltas of native libraries by taking advantage of the specific ways in which compiled native code changes between versions.
This is how much change will affect on Google Chrome patch update on Play Store:
|Patch Description||Previous patch size
|M46 to M47 major update||22.8 MB||12.9 MB|
|M47 minor update||15.3 MB||3.6 MB|
So now you will get reduced app update size on Google Play Store.
