All breaking changes in the 2.0 release revolve around ammending incorrect
or updated method signatures in signal_analog. The below table illustrates
the changes between releases:
| 1.x Method Signature | 2.x Method Signature | Documentation |
|---|---|---|
bottom(by=None, over=None) |
bottom(count=None, percentage=None, by=None) |

Charts and Notifications optionally accept Program statements in place of raw
flow statements. With version 2 of the library these Program objects will
now run through a series of validations in order to warn or prevent bad programs
from being sent to SignalFx.
Validations are now defined in the Programs.validate method and can
optionally make use of user-defined validations.
The only default validation for the 2.0 release is one that verifies that
at least one statement in a Program is published. This may invalidate
previously accepted Programs.
