The semantic versioning of this release is a bit particular since it only includes changes in the Go wrapper without any changes from the upstream C repository (https://github.com/facebook/zstd/releases).

Changes:

• Pass pointers to C as unsafe.Pointer, not uintptr (memory corruption) @evanj (https://github.com/DataDog/zstd/pull/91)
• Add go.mod file @Viq111 (https://github.com/DataDog/zstd/pull/94)
• [circleci] Fix 32 bits builds @Viq111 (https://github.com/DataDog/zstd/pull/92)

This is a recommended version as it fixes a potential memory corruption bug when the system is under-pressure (memory and/or lots of threads) which forces the Go runtime to move the stack around.

edit: This version went back to pre-release as it contains a bug when using a Writer object from another package (see https://github.com/DataDog/zstd/pull/97)
