October 2025 monthly summary for arXiv/arxiv-browse: Delivered the phase-out of the legacy notification service integration. Removed references to the sorryapp notification service from the base HTML template and deleted links for email and Slack notifications via sorryapp to complete the deprecation of the status notification workflow. This reduces external dependencies, simplifies notification routing, and mitigates risks associated with deprecated services. The change aligns with the roadmap to streamline notification infrastructure and lowers ongoing maintenance. Implementation tracked in commit 47d26ca0b0d9922940fde725bde56c5fe7dacc1f.

Bulgarian localization for Typst UI completed in 2024-11. This feature adds a Bulgarian translation file and registers it within the library's language constants so UI elements and messages render in Bulgarian. The work strengthens accessibility and supports our internationalization (i18n) roadmap by enabling Bulgarian-speaking users to interact with Typst without language barriers. No major bugs were fixed this month; the focus was on delivering a solid localization feature and establishing a scalable workflow for future locales.
