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

{p 5 9 2}
{* fix}
2.  The {cmd:drop} and {cmd:keep} dialog did not enable the drop and keep
    checkboxes on Macintosh platforms; this is fixed.

{p 5 9 2}
{* fix}
3.  {help ltable} ignored the {cmd:ciopts()} option; this is fixed.

{p 5 9 2}
{* fix}
4.  {help tsappend} exited with an error when applied to panel data if the
    {cmd:panel()} option was not specified; this is fixed.

{p 5 9 2}
{* fix}
5.  {help xtregar:xtregar, fe} did not print warning messages for variables
    dropped due to collinearity; this is fixed.


{hline 8} {hi:update 17jun2003} {hline}

    {title:Ado-files}

{p 5 9 2}
{* enhancement}
1.  {help cumul} has a new {cmd:equal} option; see help {help cumul}.

{p 5 9 2}
{* enhancement}
2.  {help ds} has new options that allow you to list variables that match
    certain criteria.  The resulting list is returned in {cmd:r(varlist)},
    which can then be used in a subsequent command.  The new options for
    {cmd:ds} are {cmd:not}, {cmd:has()}, {cmd:not()}, {cmd:insensitive},
    {cmd:detail}, and {cmd:indent()}.  See help {help ds} for details.

{p 5 9 2}
{* fix}
3.  {help graph} suboptions {cmd:label}, {cmd:nolabel}, {cmd:tick}, and
    {cmd:notick} of the {cmd:ylabel()}, {cmd:xlabel()}, {cmd:ytick()}, and
    {cmd:xtick()} options were not honored if {help by_option:by()} was also
    specified; see help {help axis_label_options}.  This has been fixed.

{p 5 9 2}
{* fix}
4.  {help graph_box:graph box} no longer draws a symbol for an outside value
    at the median when all observations for a variable (or the by group) for a
    box are constant.

{p 5 9 2}
{* fix}
5.  {help xpose} now uses the {help file} command instead of the
    {help outfile} and {help infile1:infile} commands and thus is better able
    to retain precision for variables of type {help double} when the
    {cmd:promote} option is specified.


{hline 8} {hi:update 03jun2003} {hline}

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {help bootstrap}, {help jknife}, {help permute}, {help simulate}, and
    {help statsby} exited with an error when the user-supplied command
    contained double quotes; this is fixed.

{p 5 9 2}
{* fix}
2.  {help ps_options:graph set ps fontface} and
    {help eps_options:graph set eps fontface} returned an error, and
    {help eps_options:graph set eps} displayed settings for {cmd:ps} rather
    than for {cmd:eps}; this is fixed

{p 5 9 2}
{* fix}
3.  {help twoway_histogram:graph twoway histogram} and {help histogram} could
    produce one less bin than it should have, resulting in the last bin
    falling short of the maximum value of the given variable; this is fixed.

{p 5 9 2}
{* enhancement}
4.  {help gsort} now has option {cmd:mfirst} for specifying that missing
    values are to be placed first in descending orderings rather than last.

{p 5 9 2}
{* fix}
5.  {help jknife} stopped with an error when it should have posted a missing
    value for a requested statistic; this is fixed.

{p 5 9 2}
{* fix}
6.  {help roctab} could produce ROC graphs with different connecting lines
    with repeated calls using the same data even though the plotted points
    were the same; this is fixed.

{p 5 9 2}
{* fix}
7.  {help sts:sts graph} with the {cmd:yscale(log)} option now graphs only the
    nonzero values.

{p 5 9 2}
{* fix}
8.  {help svytab} reported an error when the {cmd:stubwidth()} option was
    supplied with a value greater than 32 and a value label also exceeded 32
    characters.  The upper limit is now mentioned in the help file, and
    {cmd:svytab} uses 32 when supplied with a stubwidth greater than 32.


    {title:Stata executable}

{p 5 9 2}
{* enhancement}
9.  {help factor:factor, ipf} has new option {cmd:citerate()} that controls
    the number of iterations for reestimating the communalities; see help
    {help factor}.

{p 4 9 2}
{* fix}
10.  {help hexdump} incorrectly reported the count of the end-of-line
     character for Macintosh, reporting instead the count for Unix; this is
     fixed.

{p 4 9 2}
{* enhancement}
11.  {help lngamma:lngamma()} function is now computed with approximately 16
     digits of accuracy.

{p 4 9 2}
{* fix}
12.  {help memory:set memory {it:#}g}, with {it:#}>4 on 32-bit computers, now
     produces a more descriptive error message.

{p 4 9 2}
{* fix}
13.  {help manovatest:test after manova} could cause Stata to crash
     when presented with invalid syntax; this is fixed.

{p 4 9 2}
{* fix}
14.  {help update} is faster.  Stata no longer waits for the web server to
     respond if the requested file is 0 bytes.

{p 4 9 2}
{* fix}
15.  {help tempfile:temporary file names} remain unique longer.  The total
     number of unique names that are cycled through has been increased from
     1.3 million to 1.5 billion.

{p 4 9 2}
{* enhancement}
16.  {help version} has new option {cmd:born()} and issues more descriptive
     error messages.  In addition, the help file has been updated to
     be more understandable; see help {help version}.

{p 4 9 2}
{* enhancement}
17.  (Windows) An "Edit--Copy Table as HTML" menu item has been added.

{p 4 9 2}
{* fix}
18.  (Windows) {help graph_pie:Pie slices} with a 0-length arc drew a complete
     circle; this is fixed.

{p 4 9 2}
{* enhancement}
19.  (Macintosh) Shift-clicking in the {help doedit:Do-file Editor} now
     selects text from the insertion point to the text location where
     you click the mouse.

{p 4 9 2}
{* enhancement}
20.  (Macintosh)
     The ability to undo or redo multiple actions has been added to the
     {help doedit:Do-file editor}.

{p 4 9 2}
{* fix}
21.  (Macintosh) Styled text from the clipboard no longer is pasted into the
     {help doedit:Do-file editor} as styled text rather than mono-styled text.

{p 4 9 2}
{* enhancement}
22.  (Macintosh) The General Preferences dialog has a new option for
     bringing all open Stata windows to the front when Stata is activated.
     This prevents Stata's windows from overlapping with other application
     windows when Stata is brought to the front.

{p 4 9 2}
{* fix}
23.  (Macintosh) In later versions of the OS X operating system, a hidden
     progress bar incorrectly draws content that was previously over the
     control's boundaries.  Stata now works around this bug and displays the
     progress bar as indeterminate when establishing a connection (no progress
     bar was shown previously when establishing a connection).

{p 4 9 2}
{* fix}
24.  (Windows, Macintosh, and Linux) {help odbc} could load values incorrectly
     when the variables were explicitly specified in an order that did not
     match that of the underlying data; this is fixed.

{p 4 9 2}
{* fix}
25.  (64-bit Solaris GUI) Some keystrokes could be omitted or corrupted.
     Stata now links against a newer version of GDK in which this is fixed.

{p 4 9 2}
{* enhancement}
26.  (HP Unix GUI) Stata is now approximately 30% faster.


{hline 8} {hi:update 12may2003} {hline}

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {help estimates}, under rare conditions, would not restore {cmd:e(sample)};
    this is fixed.

{p 5 9 2}
{* enhancement}
2.  {help est_table:estimates table} now allows you to specify more models.
    It wraps the table if necessary.  {cmd:estimates table} also has new
    options

{p 13 17 2}
        {cmd:equations()} to match equations by number rather than by name.

{p 13 17 2}
        {cmd:coded} to display the table in a symbolic compact format in which
        numbers are represented by a single *.  This enables the display of a
        large number of models in a single table.

{p 13 17 2}
        {cmd:modelwidth()} to set the number of characters for displaying
        model names.

{p 9 9 2}
    See help {help est_table}.

{p 5 9 2}
{* fix}
3.  {help est_table:estimates table} produced an error message if the table
    included many coefficients or the {cmd:label} option was specified with
    models, such as {help ologit}, that contain special names in the
    coefficient vector name stripe (such as {cmd:_cut{it:#}} with {cmd:ologit});
    this is fixed.

{p 5 9 2}
{* fix}
4.  {help graph_display:graph display} labeled graph bars with zero height
    when redisplaying a graph that was drawn using
    {help graph_bar:graph bar, stack} or {help graph_bar:graph hbar, stack}
    even though {cmd:blabel()} was not specified; this has been fixed.

{p 5 9 2}
{* fix}
5.  {help twoway_function:graph twoway function} renamed a variable that
    started with x to "x" if there was only one such variable; this is fixed.

{p 5 9 2}
{* fix}
6.  {help twoway_histogram:graph twoway histogram} reported an error when
     more than 999 bins were involved; this is fixed.

{p 5 9 2}
{* enhancement}
7.  {help twoway_fpfit:graph twoway fpfit} and
    {help twoway_fpfitci:graph twoway fpfitci}
    now produce smaller .gph, .ps, .eps, and .wmf files.

{p 5 9 2}
{* fix}
8.  {help lrtest} and {help suest} now work correctly for models having zero
    parameters (e.g., the null model for Cox regression).

{p 5 9 2}
{* fix}
9.  {help recode} with an {cmd:if} condition involving strings that contained
    spaces produced an error; this is fixed.

{p 4 9 2}
{* fix}
10.  {help svyheckman}, {help svyheckprob}, and {help svynbreg} computed
     confidence intervals using the wrong degrees of freedom for some
     parameters:  athrho, lnsigma, and lambda for {cmd:svyheckman}; athrho for
     {cmd:svyheckprob}; and lnalpha and lndelta for {cmd:svynbreg}.  This is
     fixed.

{p 4 9 2}
{* enhancement}
11.  {help svytab} has a new {cmd:notable} option that
     suppresses the header and table and presents only the test statistics, if
     any; see help {help svytab}.

{p 4 9 2}
{* fix}
12.  {help vwls} returned the error "{error:no observations}"
     when the computed variances were large; this is fixed.

{p 4 9 2}
{* fix}
13.  {help xtpcse} did not allow time-series operators when options
     {cmd:hetonly} or {cmd:independent} were specified; this is fixed.
