Re: [limesurvey-developers] release notice for 1.92 RC1

[Thibault Le M. <Thi...@su...>]

Hi Tom,
Hi Carsten,


As you were able to figure out I was completely unable to work on LS  
for the last 2 months for professionnal and medical reasons.

I guess I may have some time for LS this week (holidays for me), so if  
you need help in releasing 1.92RC1 officially (preparing packages,  
upload to sf.net, ...), let me know.

Thibault

>    {INSERT:SGQA} syntax.
>    - Write complex expressions using 70+ mathematical/date/string
>    functions, parentheses, and any math/logic operators.
>    - Use cascading conditional logic, like cascading array_filter /
>    array_filter_exclude.
>    - Eliminate the need for most custom JavaScript - computations, scoring
>    and tailoring are done by EM.
>    - Run surveys with complex conditions and piping in All-in-one mode,
>    even if highly dynamic.
>    - Run large, complex surveys faster, even if they contain many
>    conditions.
>    - Use the Question/Group Navigation Index even with complex conditions.
>    - Jump forward in Navigation Index, re-validating all intervening steps
>    and stopping if any are invalid.

>    Conditions editor if you like it.
>    - Re-order and/or delete any questions or groups, even if they contain
>    complex conditions.
>    - Use EM syntax-highlighting to quickly validate and debug your work.

>    code, SGQA, question text, and enumerated answer choices. Clicking on the
