No, 1.5.5 was the end of that line.

Let me explain our versioning:

- 1.odd numbers (1.5.x) are "Feature" series.
- 1.even numbers (1.6.x) are "Stable" series.

1.6 is just a re-naming from the 1.5 series (i.e., it's not a new branch from the trunk). It represents the maturity of a feature series. Once it transitions to 1.6/stable, no new features can be added/removed -- only bug fixes.

See if you care for more info.

So I committed the ARM patch against the trunk and filed a CMR for 1.6.
