Hey everybody,

Two big shifts this week: Python 3.14 lands with the most meaningful ergonomics + concurrency update in years, and Microsoft starts moving GitHub infra to Azure—huge implications for Copilot scale. I’ve also got my new video on the 10 AI concepts every dev should know.

🚀 A Big Release: Python 3.14

Python 3.14 Is Out
Python 3.14 officially released, introducing features like free-threaded builds (opt-in GIL removal), template strings (PEP 750), deferred evaluation of annotations (PEP 649), and smarter error messages and debuggers. If you maintain Python code, this is one to test soon.

How Fast Is Python 3.14? Benchmarks
Miguel Grinberg ran performance comparisons right after 3.14 dropped seeing which workloads improved, where regressions might lurk, and practical guidance for early adopters.

🛠️ Platform & Tools

Microsoft Moves GitHub Infrastructure to Azure
Microsoft is migrating all of GitHub’s infrastructure into Azure over the next ~18 months. The move is driven by scaling needs (especially for AI/Copilot features) and tighter integration with Microsoft’s cloud ecosystem.

AI Is Revolutionizing Software Development: How OpenAI’s Andy Brown Sees the Shift
At Tech Week Singapore, OpenAI’s Andy Brown argued that AI is changing not just what companies build, but how they build it, moving away from long sprint cycles to continuous release workflows, powered by rapid AI iteration.

⏱️ Try This in 5 Minutes

Spin up Python 3.14 locally and sanity-check new behaviors:

# If you use pyenv:
pyenv install 3.14.0 && pyenv virtualenv 3.14.0 py314 && pyenv local py314

python - <<'PY'
from string import Template
print(Template("Hello, $name").substitute(name="Travis"))

try:
    1/0
except Exception as e:
    # Observe improved tracebacks / hints
    raise
PY

Result: Quick feel for t-string ergonomics and nicer exceptions before deeper perf tests.
