Real Python interviews Seth Larson, the PSF's Security Developer in Residence, about supply chain defense. PyPI now limits version strings to 128 characters, a change affecting only two of roughly 10 million existing releases. Python 3.15.1, 3.14.9 and 3.13.17 have been released, and a new profiling module organizing built-in profiling tools ships in Python 3.15. Experimental uv-ty integration adds unified CLI and editor support via a new uv check command. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the new maximum length for a PyPI package version string? PyPI now limits version strings to 128 characters. Across roughly 10 million existing releases, only two had version strings longer than that limit, so the change affects almost no one. The limit exists mainly to keep page rendering reasonable for projects, and it applies only to PyPI itself, not to tools like pip or uv. _Track packaging changes like this PyPI version limit as you maintain Python dependencies with daily.dev._ ### Which Python patch versions were released together recently? Python 3.15.1, 3.14.9, and 3.13.17 were released together as coordinated patch updates across three active release branches. This keeps the three most recent minor versions updated with fixes simultaneously, following Python's standard maintenance release cadence. _Developers tracking Python patch releases follow updates like these on daily.dev to stay current._ ### What does the new profiling module do in Python 3.15? The profiling module introduced in Python 3.15 organizes Python's built-in profiling tools under a single unified module. It consolidates previously scattered profiling utilities to make performance analysis more discoverable and consistent across the standard library. _Python developers optimizing performance keep up with standard library changes like this via daily.dev._ ## Similar posts on daily.dev - [Python 3.15.0a8, 3.14.4 and 3.13.13 are out\!](https://daily.dev/posts/python-3-15-0a8-3-14-4-and-3-13-13-are-out--fpknzjqcr) · Python Insider · 29 upvotes · 1 comments - [PyCoder’s Weekly](https://daily.dev/posts/pycoder-s-weekly-oqwpneq66) · Planet Python · 0 upvotes · 0 comments - [A New Python Packaging Council and Other News for May 2026 – Real Python](https://daily.dev/posts/a-new-python-packaging-council-and-other-news-for-may-2026-real-python-j4ikhcce9) · Real Python · 0 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#django](https://daily.dev/tags/django) [View this post on daily.dev](https://daily.dev/posts/pycoder-s-weekly-1bms4mrky) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"PyCoder’s Weekly","url":"https://daily.dev/posts/pycoder-s-weekly-1bms4mrky","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/pycoder-s-weekly-1bms4mrky"},"datePublished":"2026-10-27T19:53:43.179Z","dateModified":"2026-10-27T20:15:50.082Z","description":"This issue of PyCoder's Weekly covers Python security, performance and new tooling.
