We're happy to announce Amelia 1.6.4. Updates include:

* Fixes recent slowdown and errors in Amelia under R-2.15.2. 

* New arguments to tscsPlot() to allow for plotting multiple cross-sectional units on the same panel. 

* Maintainer emails have been updated to real email addresses.

* Removed the "Hold in R memory" output option in AmeliaView. This violated CRAN policies. (We'll try to bring it back)

* Minor bug fixes.

You can install the new version using the following code:

install.packages("Amelia", repos = "http://cran.r-project.org", type = "source")

The new version should populate to other CRAN mirrors over the coming days. Please let us know if you see any issues.
