Does anybody know what was fixed in this patch update? TIA

Open Issues:

(30257) Streaming ThreadAbort Exceptions

Should this thread be re-titled "WL6 Pro/Dev 6.2.46 patch" ?

Open Issues does NOT show "(26535) GetExternalSymbol does not populate Named DataSeries" as being fixed, whereas does my WLD 6.1 startup Home Page DOES show this as being fixed.

Should this Open Issue be marked as fixed? Also, is it likely that any of the other "Named DataSeries bugs" have been fixed?

No, it's not fixed.

I have just seen the same problem. If you are working with an external time series "GetExternalSymbol". If I switch to an another time range (f.ex. from daily to weekly), I get an error message.

I suppose it is this problem mentioned below:

Versions 6.0-6.2:

•(13937) Named series are lost with some data loading range settings

?Named DataSeries are present in the data when "Load All Data" is selected and lost when switching to some data loading range settings like X bars, Y months/etc., Date range. Applies to all providers that register named series, such as ASCII or TradingBlox.

No, it's not the same issue - and most likely is not a bug. Look up Named DataSeries related functions in the QuickRef to have an understanding of the concept. Then search that error message in the Wiki and here on the forum. If a solution couldn't be found (that's unlikely), please start a new forum thread with more details: error message text, data providers.

I found a solution to my problem:

I use now
Bars GetExternalSymbol(string dataSetName, string symbol, bool synchronize);
instead of:
Bars GetExternalSymbol(string symbol, bool synchronize);

The external data are in ASCII database. If I specify the dataSetName, than the code works if I am swichting form "Daily" to "Weekly" or "Monthly" and back.

These days it is scary to download any upgrades. This the is the second upgrade this year that caused the application crashed. I stopped accepting the prompt for upgrade.

See Wealth-Lab crashes on start: scroll down to "General troubleshooting procedure". Good luck.
