     been fixed.

{p 4 9 2}
{* enhancement}
11.  {help roccomp} with the {cmd:graph} option now supports turning off the
     default grid lines using the {cmd:ylabel(,nogrid)} and

{p 4 9 2}
{* enhancement}
12.  {help sampsi} now

{p 9 13 2}
    a.  has a new option {cmd:nocontinuity}.

{p 9 13 2}

{p 4 9 2}
{* fix}
13.  {help separate} with the missing option failed if the variable contained
     extended missing values ({cmd:.a}, {cmd:.b}, ..., {cmd:.z}); this has
     been fixed.

{p 4 9 2}
{* fix}
14.  {help stcurve} added an extra space between the filename and the
     extension if the filename was quoted in the outfile() option; this has
     been fixed.

{p 4 9 2}
{* fix}
15.  {help svyprop} with the {opt subpop()} option could incorrectly exit with
    a "stratum with only one PSU detected" error; this has been fixed.

{p 4 9 2}
{* enhancement}
16.  {help tabodds} now interprets {cmd:base(}{it:#}{cmd:)} as the category
     number of {it: expvar} when options {cmd:or base()} are used with option
     {cmd:cornfield}, {cmd:tb}, or {cmd:woolf}.

{p 4 9 2}
{* fix}

{hline 8} {hi:update 06oct2004} {hline}

    {title:Stata executable, Windows}

{p 5 9 2}
{* fix}
1.  (Windows GUI only) The 05oct2004 update introduced a problem in the
    {help Viewer} that caused Stata to crash; this has been fixed.

{p 5 9 2}
{* fix}
2.  (Windows GUI only) As of the 05oct2004 update, closing Stata while a
    dialog was open would cause a harmless exception error; this has been
    fixed.


{hline 8} {hi:update 05oct2004} {hline}

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {help areg}, after the 20aug2004 update, reported a missing value for the
    F statistic when the model was not full rank, even in cases when it should
    have reported an F statistic; this has been fixed.

{p 5 9 2}
{* fix}
2.  {help bsample} without the {cmd:strata()} and {cmd:cluster()} options
    ignored the {help if} qualifier; this has been fixed.

{p 5 9 2}
{* enhancement}
3.  {help clonevar} is a new command that makes an identical copy of an
    existing variable; see help {help clonevar}.  This command is based on
    work by Nicholas J. Cox, University of Durham.

{p 5 9 2}
{* fix}
4.  {help codebook} failed if one of the variables had a large number of
    {help labels:value labels}; this has been fixed.

{p 5 9 2}
{* fix}
5.  {help graph pie} option {cmd:plabel( ... , gap())} would be applied to
    subsequent graphs even if the option were not specified on the subsequent
    {cmd:graph} command.  This has been fixed.

{p 5 9 2}
{* fix}
6.  {help graph twoway connected} ignored the {cmd:sort} option when a weight
    was specified; this has been fixed.

{p 5 9 2}
{* fix}
7.  {help irf} refused to estimate the IRFs after estimating a univariate VAR
    via {help var}; this has been fixed.

{p 5 9 2}
{* fix}
8.  {help lroc} now preserves the sort order of the data.

{p 5 9 2}
{* enhancement}
9.  {help mfp} has a new option, {cmd:aic}, for selecting models by the Akaike
    information criterion (AIC); see help {help mfp}.

{p 4 9 2}
{* fix}
10.  Many commands were updated for better version-control handling of
     {help missing:extended missing values}.  See item #20 below.


    {title:Stata executable, all platforms}

{p 4 9 2}
{* enhancement}
11.  {cmd:gllamm} now has more utility programs internalized in Stata's
     executable, further speeding up estimation for certain classes of models,
     including models with composite links and latent class models with class
     membership determined by covariates.  See
     {browse "http://www.gllamm.org"}.

{p 4 9 2}
{* fix}
12.  {help dfmt:format} date and time modifiers '{cmd:c}' and '{cmd:y}' did
     not omit leading zeros when they should have.  They behaved exactly like
     '{cmd:C}' and '{cmd:Y}'.  This has been fixed.

{p 4 9 2}
{* fix}
13.  {help graph export} created invalid PostScript or Encapsulated PostScript
     files when graph labels were longer than 128 characters; this has been
     fixed.

{p 4 9 2}
{* enhancement}
14.  {help ibeta():ibeta(a,b,x)} has been improved to 10 digits of accuracy
     when {bind:0 < a, b < 100,000}.  Additionally, functions {help atan()},
     {help asin()}, and {help acos()} now have greater accuracy.

{p 4 9 2}
{* fix}
15.  {help matrix opaccum} and {help matrix glsaccum}, with a string group
     variable {cmd:group()}, caused Stata to crash; this has been fixed.

{p 4 9 2}
{* fix}
16.  {help predict:predict, r} is documented as the minimal abbreviation for
     obtaining residuals after many estimation commands, yet in some cases,
     such as {help regress} with robust standard errors, a minimal
     abbreviation of {cmd:re} was required.  {cmd:predict} now allows {cmd:r}
     as the minimum abbreviation.

{p 4 9 2}
{* enhancement}
17.  {help set varabbrev} is a new command that allows users to turn off
     variable abbreviation in Stata.  See help {help set varabbrev}.

{p 4 9 2}
{* enhancement}
18.  {help tabulate} and {help tabi} with the {cmd:exact} option are now
     significantly faster; see help {help tabulate}.

{p 4 9 2}
{* fix}
19.  {help tabulate} with both the {cmd:generate()} and {cmd:missing} options
     generated a dummy variable containing {cmd:.} rather than {cmd:1} for
     observations where varname was equal to missing; this has been fixed.

{p 4 9 2}
{* fix}
20.  {help version:version #, missing} ignored the {cmd:missing} option in the
     standalone case.  When used in a one-line manner, such as {cmd:version}
     {it:#}{cmd:, missing :} {it:cmd}, it caused an ado-file with {it:#} less
     than 8 to understand the extended {help missing:missing values}.  Now, in
     all cases, the {cmd:missing} option causes Stata to adopt the
     missing-value behavior of the calling program.  That is, an ado-file with
     {cmd:version} {it:#}{cmd:, missing}, when called by a program that
     understands extended missing values, will also understand extended
     missing values.  {cmd:version} {it:#}{cmd:, missing}, when called by a
     program that does not understand extended missing values, will also not
     understand extended missing values.

{p 4 9 2}
{* fix}
21.  {help window stopbox} with long text caused Stata to crash.  Stata now
     accepts text up to 500 characters in each argument, and if the limit is
     exceeded, a warning message is given.

{p 4 9 2}
{* fix}
22.  When you pasted into a single cell, the {help edit:Data Editor} could
     interpret a string containing a comma as two cells; this has been fixed.

{p 4 9 2}
{* fix}
23.  Specified heights for {help dialog} {cmd:VARLIST} and {cmd:VARNAME}
     controls are now ignored, and the default height is always used.


    {title:Stata executable, Windows}

{p 4 9 2}
{* enhancement}
24.  You can now paste to the Command window when the Results, Graph,
     Variables, or Review window is in the front by selecting Paste Text in
     Command Window from the Edit menu.

{p 4 9 2}
{* enhancement}
25.  Variable Properties, Sort, Hide, and Delete menu items have been added to
     the contextual menu of the {help edit:Data Editor}.

{p 4 9 2}
{* fix}
26.  {help dir} now handles file sizes greater than 2 GB.  The output of
     {cmd:dir} was changed slightly to better accommodate these large file
     sizes.

{p 4 9 2}
{* fix}
27.  The dropdown portion of {help dialog} {cmd:COMBOBOX} controls now resizes
     based on the longest text contained in their initial list.

{p 4 9 2}
{* fix}
28.  If you pressed Enter in a dialog without an OK button or pressed Esc in a
     dialog without a Cancel button, Stata crashed.  This has been fixed.

{p 4 9 2}
{* fix}
29.  A timing issue with the Windows Save As dialog caused an error when you
     tried to save a dataset to a floppy drive.  This has been fixed.


    {title:Stata executable, Macintosh}

{p 4 9 2}
{* enhancement}
30.  You can now paste to the Command window when the Results, Graph,
     Variables, or Review window is in the front by selecting Paste Text in
     Command Window from the Edit menu.

{p 4 9 2}
{* enhancement}
31.  Variable Properties, Sort, Hide, and Delete menu items have been
     reorganized on the contextual menu of the {help edit:Data Editor}.

{p 4 9 2}
{* enhancement}
32.  The floating Toolbar can now be resized.

{p 4 9 2}
{* fix}
33.  If the Toolbar was anchored, and you clicked the Zoom button of a window,
     the titlebar of the window would be obscured by the Toolbar.  This has
     been fixed.

{p 4 9 2}
{* fix}
34.  Results and {help viewer:Viewer} windows could not be resized to the full
     width of the screen; this has been fixed.

{p 4 9 2}
{* fix}
35.  When you printed from the {help viewer:Viewer}, the margins would be
     incorrect causing part of the header not to print and the output to be
     printed with no left margin.  This has been fixed.

{p 4 9 2}
{* fix}
36.  When printing long documents from the {help doedit:Do-file Editor}, Stata
     crashed or might not print the last page.  Both problems have been fixed.

{p 4 9 2}
{* fix}
37.  Right-justified text drawn in the Graph window sometimes was off by a
     pixel or two; this has been fixed.

{p 4 9 2}
{* fix}
38.  The dropdown variety of {help dialog} {cmd:COMBOBOX} controls did not
     scroll text correctly when long text was selected; this has been fixed.

{p 4 9 2}
{* fix}
39.  Specifying a height for some types of {help dialog} {cmd:COMBOBOX}
     controls changed the controls' position.  Now, the default height is
     always used, and the position is not affected.

{p 4 9 2}
{* fix}
40.  Small Stata crashed after drawing a number of graphs or invoking a
     sequence of dialogs; this has been fixed.


    {title:Stata executable, Unix (GUI)}

{p 4 9 2}
{* enhancement}
41.  Variable Properties, Sort, Hide, and Delete menu items have been added to
     the contextual menu of the {help edit:Data Editor}.

{p 4 9 2}
{* fix}
42.  Specifying a height for some types of {help dialog} {cmd:COMBOBOX}
     controls changed the controls position.  Now, the default height is
     always used, and the position is not affected.


{hline 8} {hi:update 01sep2004} {hline}

    {title:Ado-files}

{p 5 9 2}
{* enhancement}
1.  Online help and the search index have been brought up to date for
    {help sj:Stata Journal 4(3)}.

{p 5 9 2}
{* fix}
2.  {help dstdize}, with the 20aug2004 update, saved an incorrect {cmd:r(se)}
    matrix; this has been fixed.


{hline 8} {hi:update 20aug2004} {hline}

    {title:Ado-files}

{p 5 9 2}
{* enhancement}
1.  {help areg} now returns {cmd:e(ll)} and {cmd:e(ll_0)}, allowing the
    {help estimates table} command to compute AIC and BIC after {cmd:areg}.

{p 5 9 2}
{* fix}
2.  {help areg} did not use the number of clusters for the denominator degrees
    of freedom when the {cmd:cluster()} option was used.  The F statistic is
    now set to {help missing} if {help test} drops any variables when trying
    to compute the Wald statistic for the model.

{p 5 9 2}
