May 2025 (django/djangoproject.com) focused on robustness of payments and content rendering. Implemented atomic transactions to ensure Stripe donation subscription updates are consistent when donation interval or amount changes, preventing partial updates and mismatches between our records and Stripe. Completed a safe update path that rolls back on Stripe API errors to avoid data inconsistencies. Addressed content rendering safety by escaping special characters in image alt text during HTML/Markdown generation and added tests to verify escaping across formats, reducing rendering issues and potential security vulnerabilities. These changes are traceable to commits 152809a61a485c7eda3afe4486091323e4e2a4c1 (Fixed updating of stripe donations) and 253cc2a4499cfe0935c4e4462a3562a4650df317 (Fixed escaping of alt text in ContentFormat.img() (#2036)).
