H A DREADME.md1 # Zstd-On-ZFS Library Manual
5 This subtree contains the Zstd library used in ZFS. It is heavily cut-down by
7 intentionally unmodified. Please do not alter the file containing the zstd
8 library, besides upgrading to a newer Zstd release.
14 * `zstd-in.c` is our template file for generating the single-file library
17 future. Thus we keep them private to Zstd.
19 ## Zstd update policy
21 Since the exact compressed byte stream may change between Zstd versions, updates
24 1. Zstd may be updated, as needed, after a new .0 release is tagged.
27 3. The Zstd version will not be upgraded within a major release.
