{* enhancement}
19.  EPS files exported from Stata graphs now contain information describing
     the font that must be downloaded to the printer.  This assists desktop
     publishing applications when printing embedded Stata EPS files using a
     font that may not exist on a particular printer.

{p 4 9 2}
{* fix}
20.  EPS graph files that used the small square symbol could contain invalid
     PostScript code; this has been fixed.

{p 4 9 2}
{* fix}
21.  {help infix} and {help infile2:infile} with a dictionary had difficulty
     handling end-of-line characters from files created under different
     operating systems.  Stata for Windows and Stata for Unix did not read raw
     text files with Macintosh end-of-line characters.  Stata for Macintosh
     read a raw text file with DOS end-of-line characters as having two
     end-of-line characters.  Both problems have been fixed.

{p 4 9 2}
{* enhancement}
22.  {help label} has new subcommand {help label_language:language} that lets
     you create and use datasets that contain different sets of data,
     variable, and value labels.  A dataset might contain one set in English,
     another in German, and a third in Spanish.  Another dataset might contain
     one set of short labels and another of long labels.  Either way,
     you can switch between the label sets as desired.
     Up to 100 sets of labels are
     allowed.  See help {help label_language}.

{p 4 9 2}
{* fix}
23.  {help odbc:odbc describe} produces a more detailed error message when the
     table does not exist.

{p 4 9 2}
{* enhancement}
24.  {help odbc:odbc exec} now allows lengthy SQL statements; see help
     {help odbc}.

{p 4 9 2}
{* enhancement}
25.  {help odbc:odbc load} has a new {cmd:sqlshow} option for debugging SQL
     communication with the driver; see help {help odbc}.

{p 4 9 2}
{* enhancement}
26.  The maximum number of {help serset:sersets} has been increased from 100
     to 2,000; see help {help serset}.  This means that complex graphs and
     combined graphs can be drawn with many more plots (lines or scatters).

{p 4 9 2}
{* fix}
27.  {help tabulate} now accents the {c e'} when labeling Cram{c e'}r's V
     (obtained using the {cmd:V} option).  The value continues to be returned
     in {cmd:r(CramersV)} ({it:sans} accent).

{p 4 9 2}
{* enhancement}
28.  {cmd:test} after {help anova} and {help manova} has new options
     {cmd:mtest()}, {cmd:test()}, and {cmd:showorder}; see help
     {help anova postestimation:testanova} and {help manovatest}.
     {cmd:mtest()} provides adjustment for multiple tests.  {cmd:test()}
     allows easier specification of contrasts and other tests involving the
     coefficients of the underlying regression model.  {cmd:showorder} shows
     the order of the columns in the underlying regression model.

{p 4 9 2}
{* enhancement}
29.  {help _tsnatscale} is a new programmer command for obtaining nice label
     or tick values for time series; see help {help _tsnatscale}.


    {title:Stata executable, Windows}

{p 4 9 2}
{* enhancement}
30.  The Review and Variable windows may be jointly opened or closed by
     pressing Ctrl-9.

{p 4 9 2}
{* enhancement}
31.  The Review and Variable windows may be moved together with the main Stata
     window by holding down the Ctrl key while dragging the main Stata window
     with the mouse.

{p 4 9 2}
{* enhancement}
32.  The default actions associated with double-clicking on various Stata
     files no longer include {cmd:/m1} on the action command line.  Thus,
     the value of {cmd:set memory} ...{cmd:, permanently} will be respected;
     see help {help memory}.  You may still edit the action command line for
     all Stata file types to override the default memory allocation.  If you
     wish Stata to use the new default associations, choose
     {cmd:Restore File Associations} from Stata's {cmd:Prefs} menu.

{p 4 9 2}
{* enhancement}
33.  The path passed to Stata when a Stata file was double-clicked was
     sometimes converted to old-style 8.3 notation before being displayed in
     Stata.  This did not affect functionality but was visually unappealing.
     Windows now passes Stata nicely formatted, full paths.  This takes effect
     if you reset Stata's default file associations by selecting
     {cmd:Restore File Associations} from Stata's {cmd:Prefs} menu.

{p 4 9 2}
{* fix}
34.  The Viewer edit field now allows text to be pasted into it.

{p 4 9 2}
{* fix}
35.  The Print item in the contextual menu in the Viewer did not print the
     Viewer's contents; this has been fixed.

{p 4 9 2}
{* enhancement}
36.  (Windows XP) The visual style of Stata for Windows now matches the
     currently selected Windows theme.

{p 4 9 2}
{* fix}
37.  (Windows XP) On some Dell platforms, Stata would fail to launch due to
     another process being frozen.  If frozen processes exist, Stata now
     works around this and still launches.


    {title:Stata executable, Macintosh}

{p 4 9 2}
{* enhancement}
38.  An "{cmd:Edit--Copy Table as HTML}" menu item has been added.

{p 4 9 2}
{* enhancement}
39.  Graphs saved or copied in the PICT format now provide true rotated text
    via PICCOMMENTS.  For applications that do not understand PICCOMMENTS and
    don't know to ignore them, there is an option to turn off this feature:
    {cmd:set piccomments off} or unchecking the
    "{cmd:Use PICCOMMENTS in PICT output to draw rotated text}" checkbox in
    the {cmd:Graph Preferences} dialog.  See help {help piccomments}.

{p 4 9 2}
{* enhancement}
40.  Stata has been enhanced to support Panther, Apple's forthcoming OS X
     upgrade.

{p 4 9 2}
{* fix}
41.  Running Stata remotely in batch mode caused Stata to crash when drawing
     the progress bar on Stata's icon in the Dock.  Before attempting to draw
     the progress bar, Stata now determines whether it is being run remotely
     by checking that the environment variable {cmd:REMOTEHOST} is not empty.

{p 4 9 2}
{* fix}
42.  The Search menu was never enabled; this has been fixed.


    {title:Stata executable, Unix}

{p 4 9 2}
{* fix}
43.  (console mode) Underscores associated with the {help smcl} directive
     {cmd:{c -(}title:}...{cmd:{c )-}} did not match the indentation of the
     title; this has been fixed.

{p 4 9 2}
{* fix}
44.  (Linux) {help update:update swap} now uses {cmd:gunzip} rather than
     {cmd:uncompress}.

{p 4 9 2}
{* fix}
45.  (Solaris) license positions were sometimes tracked incorrectly; this has
     been fixed.

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {help aorder} gave a system-limit error if some of the variable names had
    the letter "d" or "e" after an initial stub and number; this is fixed.

{p 5 9 2}
{* enhancement}
2.  {help bootstrap}, {help jknife}, {help permute}, {help simulate}, and
    {help statsby} have a new {cmd:trace} option that displays a trace of the
    execution of the command being operated on.

{p 5 9 2}
{* fix}
3.  Graphics options and suboptions that accept a {help compassdirstyle} now
    respect arguments that are clock directions -- numbers 0 through 12.

{p 5 9 2}
{* fix}
4.  The {help legend_option:legend()} option of {help graph} now honors the
    {cmd:height()} and {cmd:width()} suboptions.

{p 5 9 2}
{* enhancement}
5.  {help graph_box:graph box} can now label outside values; see the
    {it:{help marker_label_options:marker label options}} suboptions of
    {cmd:marker()} and help {help graph_box}.

{p 5 9 2}
{* fix}
6.  {help graph_box:graph box} issued an error message and did not draw the
    graph if any of the variables had value labels that labeled missing
    values only; this is fixed.

{p 5 9 2}
{* enhancement}
7.  {help scatter:graph twoway scatter} now has a {cmd:jitterseed()} option
    that sets the random number seed for jittered points;
    see help {help scatter}.

{p 5 9 2}
{* fix}
8.  {help twoway:graph twoway} now honors the {cmd:xlabel(, valuelabels)}
    option even when more than one y axis is specified.  Previously, if more
    than one y axis were specified, the {cmd:valuelabels} suboption was
    ignored and numbers were shown in place of the associated value labels on
    the axis.

{p 5 9 2}
{* enhancement}
9.  {help ml} now has a {cmd:vce(oim)} option that is the preferred alias for
    the existing {cmd:vce(hessian)} option which continues to work; see help
    {help ml}.

{p 4 9 2}
{* enhancement}
10.  {help separate} now has a {cmd:shortlabel} option that specifies shorter
     variable labels are to be created; see help {help separate}.

{p 4 9 2}
{* enhancement}
11.  {help statsby} is now faster.  The improvement is based on code provided
     by Michael Blasnik, Blasnik & Associates.

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {help bootstrap}, {help jknife}, {help permute}, {help simulate}, and
    {help statsby} would exit with an error when supplied with long
    expressions; this is fixed.

{p 5 9 2}
{* enhancement}
2.  {help ci} and {help cii} now produce more accurate Poisson exact
    confidence intervals.

{p 5 9 2}
{* fix}
3.  {help intreg} with the {cmd:het()} option would, on rare occasions, issue
    an error message saying there were no observations; this is fixed.

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

{p 5 9 2}
{* fix}
5.  {help svar} displays a better error message when the specified model
    passes the order condition but fails the rank condition.

{p 5 9 2}
{* enhancement}
6.  {help tostring}, a command for converting numeric variables to string, is
    now an official Stata command; see help {help tostring}.

{p 5 9 2}
{* fix}
7.  {help varirf_create:varirf create} would fail to estimate the impulse
    response functions after some structural VAR models with long-run
    constraints.  This has been fixed.


{hline 8} {hi:update 15jul2003} {hline}

    {title:Ado-files}

{p 5 9 2}
{* enhancement}
1.  {help ci} and {help cii} have new options {cmd:exact}, {cmd:wilson},
    {cmd:agresti}, and {cmd:jeffreys} for computing different types of
    binomial confidence intervals.  The default behavior of computing exact
