# In Hugo v0.60.0 Markdown rendering library changed from Blackfriday to Goldmark.
# This broke all slides formatting: every single slide appears on the same page, one on top of the other 🤦
#
# Pinning Hugo to v0.59.1 until I make time to update Academic theme (latest stable is v4.7.0, currently using v4.0.0),
# and keep it in lock-step with Hugo version, as well as address the slides formatting issue.
