With macOS Catalina, Apple changed the Terminal's default shell from bash to zsh. If you want to stay with the bash, you now always get a banner telling you to move to zsh:
The default interactive shell is now zsh. To update your account to use zsh, please run chsh -s /bin/zsh. For more details, please visit https://support.apple.com/kb/HT208050.
This was one of the first things I noticed when switching from Mojave to Catalina. Fixing this, however, is very easy:
echo "export BASH_SILENCE_DEPRECATION_WARNING=1" >> ~/.bash_profile
Setting that environment variable is enough to make it shut up about zsh.
