Are you on the latest chainladder version?
Describe the bug in words
Pandas 3.0 breaks the package.
Amongst the detected bugs so far, the most notable is latest_diagonal, which is caused by triangle.valuation and triangle.valuation_date being out of sync.
How can the bug be reproduced?
Will create branch and provide link
What is the expected behavior?
It's hard to see us moving completely out of pandas, even after adding arrow suppport.
