PostgreSQL contributor Robert Haas has published a blog post that breaks down code contributions to PostgreSQL in 2025.

I calculate that, in 2025, there were 266 people who were the principal author of at least one PostgreSQL commit. 66% of the new lines of code where contributed by one of 26 people, and 90% of the lines of new code were contributed by one of 67 people.

Contributions to the project seem to be on the upswing; in his analysis of development in 2024, there were 229 people who were the primary authors of a commit, and 66% of new lines of code were contributed by one of 18 people. The raw data is also available.

Version 11.0 of the Wine Windows compatibility layer is out. "This release represents a year of development effort, around 6,300 individual changes, and more than 600 bug fixes." The most notable changes in this release are support for the NTSync Linux kernel module (when available), and the completion of the Windows 32-bit on Windows 64-bit (WoW64) architecture that was announced as experimental in Wine 9.0.
