Thanks Alan. Thanks to Statanow, new releases aren’t as exciting as they used to be! I’m not even sure which of the “new” features I don’t already have. Many of the new things are not things I personally want, but I am sure they will make others very happy.

[Ariel Karlinsky]

How can I update my StataNow 18.5 to 19?

When I do `update query` or `update all` I get the Stata 19 availability announcement but also that:

    Do nothing; all files are up to date.

Great stuff; thanks Alan Riley (StataCorp) and everyone at StataCorp!

Assuming I translated these dates correctly, then here’s a bit of trivia: this is the first time back-to-back releases of Stata have had spent the same time in-the-making.

Code in case anyone wants to check/fix the dates

You will receive an email from us with instructions on how to request your free upgrade to StataNow 19. Because it is a major version change, it does still require that you install the new version rather than simply update to it. All current StataNow users will receive download instructions and new license codes from us for the new version.

I'm not sure if it is a bug, but every time I open a project in Stata 19, the Project Manager does not appear, and I cannot toggle it back on. Clicking does not do anything. I have to RESTORE the project manager layout and size every time I open a project.

EDIT:

Issue fixed by reinstalling Stata.

EDIT 2:

Oops problem really wasn't fixed.

Please contact tech support and let us know which platform you're running Stata on.

This is a bug that was introduced in the Windows version of the Do-file Editor for StataNow 19 and Stata 19. We will get this fixed in an upcoming update. To work around this you can close the affected instance of the Do-file Editor and then open a new instance of the Do-file Editor. Once open, if you use the "View" menu to "Show Project Manager" and then proceed to use the "File" menu to open your existing project.

Sorry for the inconvenience. We'll get this fixed!

I quite happily installed my Stata 19 upgrade yesterday, only to discover that do files that operated perfectly well under Stata 17 & 18 now crash! After some digging I have uncovered that swindex, which I have previously been using for years effectively "kills" esttab as a command and estimation results stored for later tabulation can no longer be tabulated.

As a PhD student in the final stage of write-up, who pays out of my own pocket for my Stata, you can imagine I found this a poor show. I can't go back to my perfectly functioning Stata18, as the 1st line advice I received locally was to delete the previous release upon updating!

Is there a fix to this issue?

[Hua Peng (StataCorp)]

The simple case seems work fine:

sysuse auto
eststo: reg mpg price
esttab
swindex trunk weight length, generate(sizeindex)
esttab

Can you provide an example? And what is the error you get? Also, if you contact our sales depratment, they will help you to reinstall Stata 18 (before we can track down and fix the issue in Stata 19).

[Stephen Dorgan]

Unfortunately not in mine.... When I open a new instance of Stata 19 on my Apple Silicon Mac (Single-user 4-core MP—Parallel Edition) and use your code I get the following.....

Basically all OK until swindex is executed

Since this might take some time for us to track down the issue, I took the liberty of asking our sales depratment to contact you with the instructions of downlaoding Stata 18 installer, you should get an email from them today.

I will report back when we track down the issue.

[Stephen Dorgan]

That is super helpful, I very much appreciate it.

[Hua Peng (StataCorp)]

No problem, our sales depratment sent the email, thanks for your patience. Also, would you mind show the version information of esttab? On my machine:

. which esttab
C:\Users\hop\ado\plus\e\esttab.ado
*! version 2.1.1  10jun2022  Ben Jann
*! wrapper for estout

[Stephen Dorgan]

More than happy oblige... I get

. which esttab
/Users/Stephen/Library/Application Support/Stata/ado/plus/e/esttab.ado
*! version 1.3.2, Ben Jann, 29may2007
