Broken after last patch

After todays update the plugin is no longer compiling. Thank you

Error:

Failed compiling 'GuardedCrate.cs':
  1. The type 'System.Text.StringBuilder' cannot be used as type parameter 'T' in the generic type or method 'Pool.Free<T>(ref T)'. There is no implicit reference conversion from 'System.Text.StringBuilder' to 'Facepunch.Pool.IPooled'. [CS0311]
     (GuardedCrate 32 line 1807)​

waiting i think.

This has been fixed on version 2.0.0
