# [NTG-context] Questions about creation of PDF's

```Hi all,

I came across the following changes in behaviour of compilation. Using this minimal example

\starttext
\pdfminorversion=3
Hello!
\stoptext

I found out that since TL2010 till TL2015, the output PDF is of the version 1.3
whereas TL2016 (which I do not use), TL2017 and current ConTeXt from the
garden produce PDF of version 1.7.

Is there any other (or new) way how to set the output version directly on the source file?

Simultaneously, I found out that the produced PDF by older version -- since
TL2010 till TL2015 -- contains, e.g.,

"Creator:  ConTeXt - 2015.05.18 12:26"

whereas  TL2017 and current ConTeXt contains very short information

"Creator:  LuaTeX + ConTeXt MkIV"

Is possible to extend this information adding the date&time of the ConTeXt, similarly to the older ones?
