## Version 1.2.3

- No longer builds .Rnw vignettes to pass CRAN check

## Version 1.2.2

- No longer hard code `base_size` (font size) in `dynsimGG`.

## Version 1.2.1

- Minor internal changes to work with ggplot2 version 2.0.0.

## Version 1.2

- Demo and vignette added.

- Cleaner scenario builder now allows users to specify fitted values in a
multiple row data frame.

## Version 1.1

- Depands on gridExtra >= 2.0.0. This allows users to specify the height of
of each graph when shock values are plotted with the `shockplot.heights`
argument.

- Internal code improvements.

## Version 1.0

----- Code Break -----

!!!!No longer relies on Zelig.

- Solution: Before running `dynsim` simply estimate model with `lm` rather than
`zelig` with `model = "ls"`.

- Fixed effect examples added.

## Version 0.2.5

- Internal improvements.

- The result of `dynsim` is now both a `data.frame` and `dynsim` object.
This enables the user to find easy nongraphical summaries.

## Version 0.2.4

- Warning and error improvements for `dynsim`.

- Minor example formatting improvements.

## Version 0.2.3

- Internal: Travis CI added for build checks.

- Minor documentation improvements.

## Version 0.2.2

- Simplified the syntax for shock plots (`shockplot = TRUE` is no longer
necessary) and decreased the font size.

## Version 0.2.1

- Added a `shockplot` to `dynsimGG`. This allows you to include a plot of one
shock variable's fitted values below the main prediction plot.

- `num` argument added to `dynsim` allowing the user to specify how many
simulations to run at each point in time.

- Fixed simpler `scen` objects.

- Minor documentation fixes.
