Usage tips

As an adverb, 'bislang' (so far) can stand in different positions in the sentence. If it stands in position 1, the verb follows directly after it (inversion). However, it can also stand after the conjugated verb in the middle of the sentence.
EXAMPLE
Bislang habe ich nichts von ihm gehört.
So far, I haven't heard anything from him.
Register and style
'Bislang' (so far) belongs more to written language or a somewhat more formal style. In everyday conversation, 'bis jetzt' (until now) or 'bisher' (so far) is used more often.
EXAMPLE

Implicit contrast
The use of 'bislang' (so far) often suggests that the described state only applies up to the present moment and could change in the future. It often prepares for a contrast that can be introduced with 'aber' (but).
EXAMPLE

bislang vs bisher
so far
'bisher' and 'bislang' mean almost the same thing in this use: something has been this way so far, or has not happened so far. In many sentences, you can swap the two words. 'bisher' sounds very natural and common in everyday language. 'bislang' sounds a little more formal or more written, but it also fits in normal conversations. So the difference is less about meaning and more about style.
bislang
Bislang gibt es keine neuen Informationen zu dem Termin.
So far, there is no new information about the appointment.
bisher
Bisher hat sich niemand für den freien Platz im Kurs gemeldet.
So far, no one has signed up for the open spot in the course.
