The post is written thinking of it to be valid in several years.
This feature is very new and only present in master branch code, but the post is written thinking of it to be valid in several years :-)
is 2.0.0alpha4 dated 2012-07-02.
If the date are before August, 28 2012, then the feature is NOT present. You can wait for the next version (alpha-5 or beta-1) and use the first option for the moment, or build it from source

Is there a typo there? Both instruction look the same to me.
The diference into "File->New..." and "File->New" are three points
with points calls a file dialog to select template, without points tried to open default template.
The next day "File->New..." was renamed "File->New From Template" to avoid comfusions.
