{hline 8} {hi:update 05jul2005} {hline}

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {helpb aorder}, when used on a variable list containing variable names
    with certain combinations of the letters '{cmd:c}', '{cmd:d}', '{cmd:e}',
    or '{cmd:f}', could exit with a 'system limit exceeded' error.  This has
    been fixed.

{p 5 9 2}
{* enhancement}
2.  {helpb icd9} and {helpb icd9p} have been updated to use the V22 codes;
    V21, V19, V18, and V16 codes were previously used.  V16, V18, V19, V21,
    and V22 codes have been merged so that {cmd:icd9} and {cmd:icd9p} work
    equally well with old and new datasets.  See help {helpb icd9} for a
    description of {cmd:icd9} and {cmd:icd9p}; type "{bf:{stata icd9 query}}"
    and "{bf:{stata icd9p query}}" for a complete description of the changes
    to the codes used.

{p 5 9 2}
{* fix}
3.  {helpb ml:ml display} now behaves as it did in Stata 8 when called under
    version control.

{p 5 9 3}
{* fix}
4.  {helpb suest} allowed estimation results from {cmd:ivreg} when it should
    have produced an error message.  This has been fixed.

{p 5 9 3}
{* fix}
5.  {helpb split}, when passed {cmd:parse("")} as an option, failed with an
    error.  {cmd:split} now understands that {cmd:parse("")} is equivalent to
    {cmd:parse()}.

{p 5 9 2}
{* fix}
6.  {helpb svy} sometimes identified a larger estimation sample in
    {cmd:e(sample)} than was actually used.  This has been fixed.

{p 5 9 2}
{* fix}
7.  {helpb xtgee:xtgee, family(binomial)} is now equivalent to
    {cmd:xtgee, family(binomial 1)} for nonbinary dependent variables as
    documented in the manual.


    {title:Stata executable, all platforms}

{p 5 9 2}
{* enhancement}
8.  Find in the {help viewer:Viewer} has been improved.  Find is no longer
    performed through a modal dialog but instead is performed from a Find bar
    that is located above the Viewer's status bar.  In addition to finding a
    search term and selecting it, the Find bar can also highlight all
    instances of the search term.  Every Viewer window has its own Find bar.
    To show or hide a Viewer's Find bar, click its Find button, press Ctrl-F
    (Macintosh users press Cmd-F), or press F3.

{p 9 9 2}
    Stata always starts a find operation from the current selection.  If there
    is no selection, Stata starts at the beginning of the document.  To
    perform a find at the beginning of a document when there is text selected,
    click on the Viewer content area to clear the selection before performing
    a find, or press Ctrl-F3.  If the Find bar's edit field has the keyboard
    focus, you may also press Ctrl-Enter to do the same.

{p 9 9 2}
    The following keyboard shortcuts are available when the Find bar is
    visible.

{p2colset 10 50 52 2}{...}
{p2col:{bf:Shortcut}{space 11}{bf:Keyboard Focus}}{bf:Action}{p_end}
{p2line}

{p2line}
{p2colreset}{...}

{p 9 9 2}
Note: Macintosh users should press the Cmd key instead of the Ctrl key.

{p 5 9 2}
{* fix}
9.  The {help dialog programming} documentation has been updated for Stata 9.
    In addition, several bugs that were present in the dialog system have been
    fixed.

{p 9 13 2}
A.  The {cmd:stata} command did not echo the command in the Results window as
    documented.  This has been fixed.

{p 9 13 2}
B.  Spaces that preceded text in a {cmd:put} command were not always handled
    properly.  This has been fixed.

{p 9 13 2}
C.  {cmd:target(stata hidden)} was not accepted with u-action buttons as
    documented.  This has been fixed.

{p 9 13 2}
D.  The {cmd:require} command did not work with heavyweight i-actions.  This
    has been fixed.

{p 9 13 2}
E.  The {cmd:VERSION} statement did not work correctly when multiple operating
    systems were specified.  This has been fixed.

{p 9 13 2}
F.  {opt onchange(i-action)} did not work with {cmd:BROWSE} controls.  This
    has been fixed.

{p 4 9 2}
{* fix}
10.  Do-files that generate a {helpb graph} and later produce an error, only
     showed the error message but did not produce the error code.  This has
     been fixed.

{p 4 9 2}
{* fix}
11.  Time-series {helpb graph}s were limited to 100 tick marks.  This has been
     fixed.

{p 4 9 2}
{* enhancement}
12.  {helpb ktau} computations are now faster.

{p 4 9 2}
{* fix}
13.  {helpb mata:Mata}'s object files ({cmd:.mo} and {cmd:.mlib} files; see
     {bf:{help m1_how:[M-1] how}}) are now stored a little differently.  This
     means that if you have any personal {cmd:.mo} or {cmd:.mlib} files, you
     must rebuild them from your source code; see
     {bf:{help mata_mosave:[M-3] mata mosave}} and
     {bf:{help mata_mlib:[M-3] mata mlib}}.
     Because this change is being made so close to the original release date,
     it is not being made under version control.

{p 4 9 2}
{* fix}
14.  {helpb mata:Mata} could mistakenly issue a subscript-out-of-range error
     for the statement {cmd:d[i]=x} when {cmd:i} was a vector.  Mata did this
     when any element of {cmd:i} exceeded {cmd:length(x)} instead of when any
     element exceeded {cmd:length(d)}.  This has been fixed.

{p 4 9 2}
{* fix}
15.  {helpb mata:Mata} produced a stack-overflow error, r(3998), in a rare
     case.  This has been fixed.

{p 4 9 2}
{* enhancement}
16.  {helpb quadchk} has new option {cmd:nofrom}.  By default {cmd:quadchk}
     starts from the previous estimation results.  Adaptive quadrature is
     sensitive to starting data, so specifying {cmd:nofrom} will often get
     slightly closer results.

{p 4 9 2}
{* fix}
17.  After {helpb set_varabbrev:set varabbrev off} an expression using
     {cmd:_b[}{it:some_abbreviated_varname}{cmd:]} worked when it should not
     have.  This has been fixed.

{p 4 9 2}
{* enhancement}
18.  {helpb xtlogit:xtlogit, re}, {helpb xtprobit:xtprobit, re},
     {helpb xtcloglog:xtcloglog, re}, {helpb xtpoisson:xtpoisson, re normal},
     {helpb xtintreg}, and {helpb xttobit} now allow up to 195 integration
     points in the {cmd:intpoints()} option.

{p 4 9 2}
{* enhancement}
19.  {helpb xtlogit}, {helpb xtprobit}, {helpb xtcloglog}, {helpb xtpoisson},
     {helpb xtintreg}, and {helpb xttobit} when specified with the
     {cmd:intmethod(ghermite)} option now allow the {cmd:constraints()} option
     for specifying constraints.

{p 4 9 2}
{* fix}
20.  The {cmd:set level} extended macro function (documented in Stata 7 and
     earlier versions) failed to work in Stata 9.  This has been fixed.


    {title:Stata executable, Windows}

{p 4 9 2}
{* fix}
21.  {helpb cd} to a UNC path (i.e., {cmd:cd \\computername\path}{it:...})
     returned {cmd:c(pwd)} as an empty string rather than the correct path.
     This has been fixed.

{p 4 9 2}
{* fix}
22.  In Stata's various file dialogs, such as {bf:File--Open}, if a user
     attempted to open or save a file across a UNC path (i.e.,
     {cmd:\\computername\path}{it:...}), Stata would prepend an extra
     backslash (i.e., {cmd:\\\computername\path}{it:...}) and cause an error.
     This has been fixed.

{p 4 9 2}
{* fix}
23.  {helpb haver} failed to load datasets that contained more than 2048
     variables.  This has been fixed.  Now, the maximum is determined by the
     {help maxvar} setting.

{p 4 9 2}
{* fix}
24.  Stata for Windows incorrectly enumerated multiple instances of Stata.
     This has been fixed.

{p 4 9 2}
{* fix}
25.  The main Stata window remained hidden when launched until the commands in
     {cmd:profile.do} completed.  This has been fixed.

{p 4 9 2}
{* fix}
26.  When a Viewer was launched upon startup of Stata (whether through
     shortcuts, double-clicking smcl files, etc.) the Viewer never appeared.
     This has been fixed.

{p 4 9 2}
{* fix}
27.  Graph window positions were not properly loaded from a named preference
     set.  This has been fixed.

{p 4 9 2}
{* fix}
28.  Copy (Ctrl-C) and Print (Ctrl-P) shortcuts failed to work in the Graph
     window.  This has been fixed.

{p 4 9 2}
{* fix}
29.  Resizing a floating Results window could result in the output not
     matching the dimensions of the window.  This has been fixed.

{p 4 9 2}
{* fix}
30.  The Results window, {help viewer:Viewer}, and {help edit:Data Editor} now
     double-buffer their contents to prevent them from flickering when resized
     or redrawn.

{p 4 9 2}
{* fix}
31.  When the Variables or Review windows were clicked and text was sent to
     the Command window, the right-click menu did not properly allow for
     Cut/Undo/Copy operations.  This has been fixed.


    {title:Stata executable, Macintosh}

{p 4 9 2}
{* fix}
32.  There is a new option to draw smooth fonts with QuickDraw and the Quartz
     graphics engine rather than drawing smooth fonts using Quartz directly.
     This allows for slightly faster, yet potentially less accurate, rendering
     of text output.  To enable or disable the option, check or uncheck the
     {bf:Draw text using QuickDraw} checkbox from the General Preferences
     dialog or {cmd:set use_qd_text} {{cmd:on} | {cmd:off}}; see
     {helpb set use_qd_text}.  When this option is enabled, the minimum font
     size for smoothing is read from the System Preferences, not Stata's
     preferences.  This enhancement requires Mac OS X 10.2 or higher.

{p 4 9 2}
{* note}
33.  Some of Stata's menus that contain hierarchical menus do not display an
     arrow to indicate that a menu item contains a hierarchical menu while
     running Stata in Mac OS X 10.4 (Tiger).  This is an issue in Tiger, not
     in Stata.  Apple is aware of this and has indicated that it will be fixed
     in a future software update to Tiger.

{p 4 9 2}
{* fix}
34.  Due to a change in how the default PATH environment variable is defined
     in Tiger from previous versions of Mac OS X, Stata now searches the
     user's home directory regardless of whether it is defined in the PATH
     variable or not.  This allows Stata to determine if a profile.do file
     exists in the user's home directory when running Stata on Tiger.

{p 4 9 2}
{* fix}
35.  In Mac OS X 10.4.x (Tiger), Stata files could not be dropped on Stata's
     Dock icon so that they will open in Stata.  This has been fixed.

{p 4 9 2}
{* fix}
36.  Setting the y resolution of graphs copied to the Clipboard using the
     Graph Preferences dialog had no effect.  This has been fixed.


{hline 8} {hi:update 21jun2005} {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 5(2)}.

{p 5 9 2}
{* fix}
2.  {helpb adjust} failed when an {cmd:if} condition involved literal strings.
    This has been fixed.

{p 5 9 2}
{* fix}
3.  {helpb ml} now documents that {cmd:ml} {cmd:display} uses {cmd:e(k_eform)}
    to determine how many equations to exponentiate when supplied with an
