Describe the change

Currently the latest releases of pecl modules get installed. There is also no way to install the latest minor version of a certain major version as far as I am aware.

Should

Install specific minor releases?

Additional context

We have maybe a case where the mongodb driver 1.6 shipped with balloon v2.6.6 docker image results in random high cpu load on the mongodb replset primary.

MongoDB: 3.4.23 (replset 3 nodes). Balloon: v2.6.7 MongoDB php driver: v1.6.0

The high load occurs since the upgrade to balloon v2.6.6 from v2.6.5 while 2.6.5 is shipped with the latest 1.5.x driver.

The cpu usage goes from the usual ~2-3GHz to over 9GHz over a time of 1-2hours and normalizes after. There are not many connections, ~60 and no slow queries at all.

I've been looking for the problem on the MongoDB replset but could not find an explanation for the high load.

Reverted back to balloon 2.6.5 on our own deployment to verify this.

This was an environment based issue and not a bug.
