Hello,

I've just tried to install the latest version of PECL ssh2 (1.3) without success.

root@php-8.0.2 in ~ $ pecl clear-cache
reading directory /tmp/pear/cache
76 cache entries cleared

root@php-8.0.2 in ~ $ pecl install ssh2-1.3
pecl/ssh2 requires PHP (version >= 7.0.0, version <= 8.0.0), installed version is 8.0.2
No valid packages found
install failed

Expected result:

Be able to install the package on PHP 8 platform !

Actual result:
--------------
