Versioning question: new zstd support introduced in patch release (v1.18.4)

[m8rge]

Hi,

First of all, thanks for the great work on this library — it’s widely used and very well maintained.

I noticed that in version v1.18.4, support for zstd was introduced and enabled by default. From my understanding, this is a new feature and also changes default behavior, not just a bugfix or minor internal improvement.

According to common Go module versioning conventions (and semantic versioning in general), introducing new functionality — especially when it affects defaults — would typically warrant a minor version bump (i.e., v1.19.0) rather than a patch release.

Using a patch version for this kind of change can be surprising for downstream users who rely on patch updates being strictly backward-compatible and low-risk.

Would you consider aligning future releases with this convention?

Thanks again for your work — just wanted to raise this for consistency and to help consumers of the library manage updates more predictably.
