[fd6130]

Hi, i'm new to this library. Is this library compatible with php 8?

[mlocati]

@fd6130 ds should be compatible with PHP 7.0, 7.1, 7.2, 7.3, 7.4 and 8.0, but not with PHP 8.1

[enumag]

@rtheunissen Could you look into this please? I checked all the extensions in my dev stack and all the PHP 8.1 incompatibilities I previously encountered in them are already fixed. This is the last extension preventing me from trying 8.1 on my project.

[mlocati]

Any ETA for a new release (on pecl)?

[jfcherng]

It compiles but will generate some deprecation warnings btw.
