I've uploaded most files for the 1.8.0 release to

However, I realize that the OS X build is not quite in sync
(doesn't have the --quiet option to quantreg). So I'll do that
build again later today.
I plan to make the release on sourceforge tonight or tomorrow
unless I hear of any last-minute issues.
Since few people seem to read the Changelog, here's a "press release"
summarising the main changes in the new version. Comments welcome.
-------------------------------------------------------------------
Version 1.8.0 of gretl is out. Here is a list of the major
changes with respect to 1.7.9:
* New commands:
- "intreg": interval (grouped data) regression
- "modprint": makes it easy for script writers to format
estimation output
* New functions:
- Add accessors $Fstat and $chisq for the overall F-statistic
or chi-square test from the last model
- mcovg(): matrix covariogram
- mpols(): enables multiple-precision OLS for user-defined
matrices
- toepsolv(): solves a Toeplitz system of linear equations
- urcpval(): gives user access to James MacKinnon's
p-values for unit root and cointegration test statistics
(tau)
* Improved commands:
- "nls" and "mle": New option --numeric to force the use of
numerical derivatives
- "fcast": allow variables for the startobs and endobs
arguments; add "rolling" k-step-ahead option
- OLS and fixed effects: add option to calculate p-value
for the Durbin-Watson statistic
- "restrict": now available for nls, mle and gmm
- "loop": now more robust, more efficient and more general
- "gnuplot": now works in loops (batch mode only)
* Obsoleted commands: "rhodiff" and "hccm"
* Switch to compact tabular form for presenting model statistics
* Graphical User interface:
- Add model menu item: "Modify model", under the Edit menu,
provides a clone of the model specification
- graph controller: new facility to add a line, defined
via a formula, to an existing graph;
- line-color selector: extend to 6 colors, and
distinguish between setting the "palette" and setting
ad hoc colors for a specific graph
- Boxplots: hand the production of these over to gnuplot
- relocate user-defined scalars from main window to the
icon view window;
- many other small improvements
* Data filters
- add importer for SPSS .sav files
- CSV importer: try to handle time-series data in reverse
chronological order
* Computational engine:
- Speed-ups for the pdf() function as applied to a
series argument
* Many, many bug fixes
