So, I had a problem - my TeX distribution is new and updated, but I need to submit a paper
to the arXiv, and arXiv has a different version of TeX distribution (currently 2016).
The main problem is biblatex, which creates an incompatible version of the bibliography .bbl file.
For this, I need an appropriate version of the biblatex package.
My solution which gives the needed version 2.8 of the .bbl file:
ftp://tug.org/historic/systems/mactex/tlmgr utility by sudo tlmgr update --selfbiblatex using sudo tlmgr install <package>biblatex with sudo tlmgr remove biblatexbiblatex (currently arXiv needs 3.5), by
downloading the corresponding release of biblatex from the biblatex github repo, and installing it.Note that
cloning the full biblatex github repo and running their install script (turns out I needed version 3.5 of biblatex)
for some reason does not give the needed version 2.8 of the .bbl file.
