Recently, I opened MikTex Console in a machine running on Ubuntu 18.04 to check for updates and several dozen of available updates were listed. I accepted them all and successfully updated everything that the console proposed.
However, after said updates, I went back to working in a .tex file I had been using and without changing anything in any of the files, a mere recompilation of my .tex into PDF generated a different rendering of the PDF. Basically, the letter spacing changed and the caption font increased.
For comparison, here's a paragraph rendered before/after the many updates were performed:
And here's a table caption rendered before/after the many updates were performed:
While those changes may seem small they are enough to completely mess up the editing I was doing in this .tex file. Therefore, my questions:
(1) what is going on here? May be some fonts got weirdly updated? The compilation log shows that main font used is \T1/ntxtlf/m/n/12.
(2) how could I fix this and revert back to the prior status quo? It is rather upsetting that updating packages will change aesthetic rendering of PDFs.
Any suggestions are welcome.
