Plugin Issues / Stable?

I upgraded our plugin 4 months ago and it had lots of issues with pending payments 85% orders working all settings were verified and correct with Trust, but we only had minor issues with the old plugin and 99% of orders fine so stuck with that old v1 trust payments plugin until we were forced to upgrade.

We need to upgrade this plugin as advised by Trust Payment before the deadline end of this month, but we are very wary as it looks like the reviews are is is still has issues.

Is this more stable now? We were waiting for this to settle down. Are we safe to update this plugin? I have not seen much advanced in terms of a new version or new positive reviews since we last upgrade and if we have similar issues to last time, the client will not be happy.

Thanks
