New features include an optional explicit-override error code enforcing the @typing.override decorator, more flexible TypedDict creation/update via a new --extra-checks flag, deprecation of --strict-concatenate in favor of --extra-checks, optional documentation links for error codes, more consistent handling of unreachable code, and an experimental --new-type-inference flag improving generic function inference. Partial Python 3.12 support was added along with numerous dataclass, mypyc, stubgen, and typeshed improvements. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does mypy 1.5 still support Python 3.7? No, mypy 1.5 dropped support for running with Python 3.7 because that Python version reached end-of-life. Developers still on Python 3.7 need to upgrade their interpreter or stay on an earlier mypy version to keep type checking their code. _Track runtime and tooling support changes like this on daily.dev before they break your pipeline._ ### How do I make mypy require the @override decorator on method overrides? Enable the explicit-override error code, either with --enable-error-code=explicit-override on the command line or enable_error_code = explicit-override in the mypy config file. Mypy then reports an error if a method overrides a parent method without using @typing.override (or the typing_extensions backport), helping catch accidental overrides. The override decorator itself lands in typing with Python 3.12. _daily.dev helps Python developers keep up with mypy configuration options like this one._ ### Why does mypy now allow TypedDict construction with ** that mixes a subset of keys? Mypy 1.5 relaxed previously overly strict checks on TypedDict creation and update operations, so constructing one TypedDict from another using ** syntax, or calling update() with a TypedDict containing only a subset of keys, is now allowed by default. Stricter checking can still be enabled with the new --extra-checks flag. _Developers debugging TypedDict type errors can follow changes like this via daily.dev._ ## Similar posts on daily.dev - [The Mypy Blog: Mypy 2.4 Released](https://daily.dev/posts/the-mypy-blog-mypy-2-4-released-frfrx4bzr) · mypy - Optional Static Typing for Python · 1 upvotes · 0 comments - [New Book Release: Python Typing](https://daily.dev/posts/new-book-release-python-typing-krwdybma9) · Planet Python · 0 upvotes · 0 comments - [From Scripts to Scale](https://daily.dev/posts/from-scripts-to-scale-z15peccf4) · Simple Thread · 0 upvotes · 0 comments - [Pyrefly 1.0: A fast, forward-looking Python linter](https://daily.dev/posts/pyrefly-1-0-a-fast-forward-looking-python-linter-k4vukcqpr) · InfoWorld · 0 upvotes · 0 comments --- Tags: [#general-programming](https://daily.dev/tags/general-programming), [#python](https://daily.dev/tags/python) [View this post on daily.dev](https://daily.dev/posts/the-mypy-blog-mypy-1-5-released-cjpfq2e44) ```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":"The Mypy Blog: Mypy 1.5 Released","url":"https://daily.dev/posts/the-mypy-blog-mypy-1-5-released-cjpfq2e44","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-mypy-blog-mypy-1-5-released-cjpfq2e44"},"datePublished":"2026-08-23T12:17:37.565Z","dateModified":"2026-08-23T13:00:06.321Z","description":"Mypy 1.5 has been released, dropping support for Python 3.7 which reached end-of-life.
