Is 1.1.x backward compatible with 1.0.x？

Hi，
We want to upgrade the snapp-java from 1.0.x to 1.1.10，but concern about the compatibility.
According to my understanding:

  1. data compressed by 1.1.x could not be decompressed by 1.0.x (Non Framing APIs)
  2. data compressed by 1.0.x could be decompressed by 1.1.x (Non Framing APIs)
    Is that right?

thanks

After some tests，it seems that the compressing apis are compatible between 1.0.5 and 1.1.10.
But not sure why someother report the compatibility issue: https://stackoverflow.com/questions/63185644/compress-and-uncompress-using-different-version-of-snappy-java-library

Snappy format itself has not been changed.

The framing format is a new addition to the snappy, and it's different from the regular snappy format. See https://github.com/xerial/snappy-java#compatibility-notes
