{hline 8} {hi:update 24feb2005} {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(1)}.

{p 5 9 2}
{* fix}
2.  After the update of 09dec2004 {help fcast graph}, {help irf graph}. 
    {help irf cgraph}, {help irf ograph}, and {help sts graph} when used with
    a monochrome scheme, such as {help scheme_s2:s2mono}, and when plotting
    more than one line, plotted all lines with the same solid style.  Each
    line is now plotted with a unique pattern.

{p 5 9 2}
{* fix}
3.  {help graph box} was not fully compliant with the new setting to turn off
    variable abbreviation {c -} {cmd:set varabbrev off}.  In the specific case
    where more than one yvar was specified in combination with the
    {cmd:over()} option, {cmd:graph box} terminated with an error message;
    this has been fixed.

{p 5 9 2}
{* fix}
4.  {help svytab} incorrectly computed the design effects when supplied with
    the {cmd:row} option with one or more of the {cmd:se}, {cmd:ci},
    {cmd:deff}, and {cmd:deft} options; this has been fixed.


{hline 8} {hi:update 10jan2005} {hline}

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {help streg} ignored the {cmd:level()} option at estimation; this has been
    fixed.

{p 5 9 2}
{* fix}
2.  {help streg} issued a meaningless error message when {cmd:noconstant} was
    specified and there were no regressors specified.  {cmd:streg} now issues
    an appropriate error message.

{p 5 9 2}
{* fix}
3.  {help rocfit} erroneously gave one-sided significance levels for
    individual parameter tests that were labeled as two-sided.  {cmd:rocfit}
    now gives the correct two-sided significance levels.


    {title:Stata executable, all platforms}

{p 5 9 2}
{* fix}
4.  {help lowess} and {help twoway lowess} produced slightly different graphs
    when run multiple times using the same data and there were ties in the
    {cmd:x} variable; this has been fixed.

{p 5 9 2}
{* fix}
5.  {help tabi} with the {cmd:exact} option after the 05oct2004 update
    sometimes reported an incorrect p-value for Fisher's exact test; this has
    been fixed.

{p 5 9 2}
{* fix}
6.  {help translate} with the {cmd:translator(smcl2log)} option caused Stata
    to exit; this has been fixed.

{p 5 9 2}
{* fix}
7.  If a matrix expression referred to a variable through observation
    subscripting, such as {cmd:matrix X[2,4] = mpg[3]}, the expression, in
    rare cases, returned missing, even though the variable contained a
    nonmissing value in the observation; this has been fixed.


{hline 8} {hi:update 20dec2004} {hline}

    {title:Ado-files}

{p 5 9 2}
{* fix}
1.  {help estimates stats} displayed correct results, but the returned results
    matrix {cmd:r(S)} had the {cmd:ll0} and {cmd:ll} columns switched; this
    has been fixed.

{p 5 9 2}
{* fix}
2.  {help sdtest} and {help sdtesti} produced an incorrect p-value for the
    two-sided F test; this has been fixed.  The format of the output has also
    been improved.

{p 5 9 2}
{* fix}
3.  {help statsby} now allows string variables in the {cmd:by()} option.


{hline 8} {hi:update 17dec2004} {hline}

    {title:Stata executable, all platforms}

{p 5 9 2}
{* fix}
1.  {help anova} with the {cmd:repeated()} option, specifying a pattern of
    repeated measure variables such that no subject had a complete set of
    observed levels, caused the {cmd:e(Srep)} matrix and the Huynh-Feldt and
    Greenhouse-Geisser epsilons to be incorrect.  The regular ANOVA results
    and the Box epsilon were not harmed.  This has been fixed.

{p 5 9 2}
{* enhancement}
2.  {help clogit} now uses better starting values and does not resort the data
    at log-likelihood evaluation.  Both changes result in faster execution
    times for most problems, notably for large datasets.

{p 5 9 2}
{* fix}
3.  {help filefilter} now accepts file paths without the need to double-quote
    the path.

{p 5 9 2}
{* enhancement}
4.  (GUI) The {dialog labeldefine_dlg:label define} dialog now allows you to
    continue adding/modifying labels until you cancel.  Stata previously
    required you to click on the Add or Modify button for each value label you
    wanted to add.

{p 5 9 2}
{* fix}
5.  (GUI) The {dialog labeldefine_dlg:label define} dialog displayed the
    numeric representations of missing values; this has been fixed.

{p 5 9 2}
{* enhancement}
6.  {help odbc load} (available for Windows, Macintosh OS X, and Linux) has
    two new options, {cmd:allstring} and {cmd:datestring}, which import either
    all data or just dates as strings; see help {help odbc}.

{p 5 9 2}
{* fix}
7.  {help postfile} with the {cmd:every()} option specified as {cmd:every(0)}
    caused Stata to crash; this has been fixed.

{p 5 9 2}
{* enhancement}
8.  {help rmdir} is a new command for removing an existing directory (folder);
    see help {help rmdir}.

{p 5 9 2}
{* fix}
9.  {help tabulate} with the {cmd:exact} option took an excessive amount of
    time if the number of rows of a contingency table was greater than the
    number of columns.  In such a case, Stata now works with the transpose of
    the table to dramatically decrease the computational time for Fisher's
    exact test.


    {title:Stata executable, Windows}

{p 4 9 2}
{* enhancement}
10.  You may now copy the contents of the Review window to the Clipboard.

{p 4 9 2}
{* fix}
11.  The {help doedit:Do-file Editor} is limited to 30K of text.  However, text
    could be pasted into the editor that would exceed this limit.  This has
    been fixed.

{p 4 9 2}
{* fix}
12.  {help dialog} {cmd:VARNAME} and {cmd:VARLIST} controls will now display
     the varlist even if there is a {cmd:--more--} condition.  Stata
     previously displayed an error message that it was busy.

{p 4 9 2}
{* fix}
13.  The {dialog labeldefine_dlg:label define} dialog showed only the first 10
     characters of a label when it was being modified; this has been fixed.


    {title:Stata executable, Macintosh}

{p 4 9 2}
{* enhancement}
14.  There is now a console version of {help specialedition:Stata/SE} for the
     Macintosh.  See {browse "http://www.stata.com"} for more information.

{p 4 9 2}
{* fix}
15.  When running Stata remotely to execute a batch job, Stata now treats the
     {cmd:-b} option as an {cmd:-e} option to prevent the alert dialog from
     appearing.

{p 4 9 2}
{* fix}
16.  Graphs created while Stata is running in batch mode no longer appear on
     the screen.

{p 4 9 2}
{* fix}
17.  {help dialog} {cmd:VARNAME} and {cmd:VARLIST} controls will now display
     the varlist even if there is a {cmd:--more--} condition.  Stata
     previously displayed an error message that it was busy.

{p 4 9 2}
{* fix}
18.  In the {help doedit:Do-file Editor}, if you found some text and selected
     Replace..., it ignored the highlighted text and skipped down to the next
     occurrence and replaced that instead.  This has been fixed.

{p 4 9 2}
{* fix}
19.  The tiling of newly opened {help doedit:Do-file Editor} windows has been
     fixed.

{p 4 9 2}
{* fix}
20.  If the {help viewer:Viewer}'s scheme was changed and Default Windowing
     was selected from the Prefs menu, the Viewer's scheme would not be
     restored to the default setting.  This has been fixed.

{p 4 9 2}
{* fix}
21.  The Viewer button on the toolbar brought up a prompt for a file to view
     when it should have just displayed the {help viewer:Viewer}; this has
     been fixed.


    {title:Stata executable, Unix (GUI)}

{p 4 9 2}
{* fix}
22.  The {help edit:Data Editor} now allows you to accept changes to the data
     when exiting, discard changes to the data when exiting, and cancel
     exiting.  It previously did not allow you to cancel exiting.

{p 4 9 2}
{* fix}
23.  When you refreshed a long file opened in the {help viewer:Viewer}, the
     Viewer would flicker as the file was being refreshed.  This has been
     fixed.


{hline 8} {hi:update 09dec2004} {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(4)}.

{p 5 9 2}
{* enhancement}
2.  {help graph twoway}, {help graph bar}, {help graph box}, and 
    {help graph dot} have a new {cmd:aspectratio()} option to control the
    aspect ratio of a graph's plot region; see help {help aspect_option}.

{p 5 9 2}
{* enhancement}
3.  The default connecting line patterns for the {help scheme s2mono:s2mono}
    and {help scheme s2manual:s2manual} schemes have been improved to take
    advantage of the increased flexibility available to schemes.  The default
    connecting line patterns drawn by {help twoway line} continue to cycle
    through dashed and dotted patterns, while those drawn by
    {help twoway connected} and {help twoway scatter} {hline 2} with the
    {cmd:connect()} option {hline 2} are now all solid.

{p 5 9 2}
{* fix}
4.  Graph margin settings made by the {cmd:margin()} option of 
    {help graph display} would "stick" and apply the same margins to all
    subsequently drawn graphs until a {cmd:discard} command was issued; this
    has been fixed.


{hline 8} {hi:update 24nov2004} {hline}

    {title:Ado-files}

{p 5 9 2}
{* enhancement}
1.  Documentation for {help graph} scheme files is now available; see help
    {help scheme files}.

{p 5 9 2}
{* enhancement}
2.  The Data menu has been slightly reorganized.  The Labels & Notes submenu
    has been split into two separate entries.  Under Labels, value labels have
    been organized into their own submenu.

{p 5 9 2}
{* fix}
3.  {help cc} and {help cci} with small numbers in the case-control table and
    when {cmd:cornfield} was specified entered an endless loop; this has been
    fixed.

{p 5 9 2}
{* fix}
4.  {help cf} produced an incorrect message when the dataset contained a
    variable named {cmd:_merge}; it now produces the correct error message.

{p 5 9 2}
{* fix}
5.  {help cf} created local macros named after every variable in the dataset.
    This could cause a naming conflict with the local macros used in {cmd:cf}.
    This has been fixed.

{p 5 9 2}
{* fix}
6.  {help clonevar} has improved error messages.

{p 5 9 2}
{* enhancement}
7.  {help duplicates report} is now {help return:r-class} and returns
    {cmd:r(unique_value)} and {cmd:r(N)}.  {cmd:r(unique_value)} is the count
    of unique observations, while {cmd:r(N)} is the total number of
    observations.

{p 5 9 2}
{* enhancement}
8.  {help graph twoway} has a new {cmd:pcycle()} option that specifies the
    number of plots on a graph before the {help pstyle:pstyles} recycle back
    to the first style; see help {help advanced options}.

{p 5 9 2}
{* enhancement}
9.  {help loneway} now allows the group variable to be a string.

{p 4 9 2}
{* fix}
