Hello,

the number after the . is the version of the transcript.

See here.

When talking/writing about transcript one should always add the information about the version and the reference genome.

In some cases it might also point to isoforms of a specific gene. But that's not gonna be the case here I think

EDIT: after consulting people from Ensembl it turns out my comment above is not holding true for the emsembl IDs, so can safely be ignored in this specific case!

Those numbers after the '.' indicate the transcript version, see also https://m.ensembl.org/info/genome/stable_ids/index.html
