And the oracle:

Go to the summary

Python 1.x (1991 – mid-90s)

• Initial release (1991): Guido van Rossum’s invention. Already had dynamic typing, exceptions, functions, modules, and high-level data types (lists, dicts, strings).

• Big idea: readability and simplicity (“executable pseudocode”).

• Earth-shaker: The language itself. At a time when scripting was Perl-dominated, Python’s clarity stood out.

---

Python 2.0 (2000)

• List comprehensions → a concise, expressive way to build lists in one line. Hugely influenced by functional programming and later spread widely in other languages.

• Garbage collection with cyclic references → no more manual memory juggling with ref cycles.

• Earth-shaker: List comprehensions fundamentally changed idiomatic Python, making it more elegant and expressive.

---

Python 2.2 (2001)

• New-style classes (unifying classes and types). Before, class Foo: ... was distinct from built-in types like int. This release made everything an object with a single inheritance model.

• Generators (via yield). Revolutionized iteration — let functions produce sequences lazily.

• Earth-shaker: Generators. They made Python truly excellent for data streaming and iteration.

---

Python 2.7 (2010)

• Last major 2.x release. Added dictionary comprehensions and set literals.

• Earth-shaker: not a feature, but end of life looming. This froze the world in a “2 vs 3” split for nearly a decade.

---

Python 3.0 (2008)

• Unicode everywhere → strings became str (Unicode), with bytes separate. Made Python a first-class citizen for the modern, international internet.

• print() as a function instead of statement.

• Removed many warts (like <>, implicit int/long distinction).

• Earth-shaker: Unicode by default. It was painful, but essential for the web era.

---

Python 3.3 (2012)

• yield from → made composing generators much more natural.

• Virtual environments (venv) → lightweight isolation of dependencies.

• Earth-shaker: venv. This made dependency management accessible to everyone, not just sysadmins.

---

Python 3.4 (2014)

• asyncio module → foundation for async/await concurrency.

• enum, pathlib modern conveniences.

• Earth-shaker: asyncio. It opened Python to high-performance networking, microservices, and event-driven programming.

---

Python 3.5 (2015)

• async and await keywords baked into the language. No longer obscure callback soup — asynchronous code looked almost synchronous.

• Matrix multiplication operator @ (for NumPy users).

• Earth-shaker: async/await. This turned Python into a serious competitor for Node.js in async I/O.

---

Python 3.6 (2016)

• F-strings (f"Hello {name}"). A massive quality-of-life improvement for string formatting. So widely loved that it instantly became idiomatic.

• Underscores in numeric literals (1_000_000).

• Earth-shaker: f-strings. Conciseness + readability = a feature devs never looked back from.

---

Python 3.7 (2018)

• Data classes (@dataclass). Removed boilerplate for simple classes.

• Context variables (for async).

• Earth-shaker: dataclasses. They changed how Python code models data, especially in APIs and configs.

---

Python 3.8 (2019)

• Walrus operator (:=). Assignment inside expressions.

• Positional-only parameters.

• Earth-shaker: walrus operator. Controversial but powerful (e.g. regex matches in if, avoiding duplication).

---

Python 3.9 (2020)

• Dictionary merge/update operators (|, |=).

• New parser (PEG-based) → allows more flexible grammar in the future.

• Earth-shaker: PEG parser. Invisible to most users, but opened the door for new syntax (like pattern matching).

---

Python 3.10 (2021)

• Structural pattern matching (match ... case). Brought modern algebraic data-type style dispatch to Python.

• Earth-shaker: pattern matching. A new paradigm for control flow, making Python more expressive for compilers, AST work, and config parsing.

---

Python 3.11 (2022)

• Major speed boost (10–60% faster) via specializing adaptive interpreter.

• Precise error locations in tracebacks.

• Earth-shaker: performance. Suddenly Python wasn’t “slow by default” anymore — CPython itself got much faster.

---

Python 3.12 (2023)

• Even more performance boosts, cleaner C API.

• Type system improvements (e.g. generic types without from __future__).

• Earth-shaker: types go mainstream. Type hints aren’t just annotations now — they’re actively shaping Python’s ecosystem.

---

Python 3.13 (2024)

• No GIL preview builds (still experimental). Removing the Global Interpreter Lock would be epoch-making for multi-core scaling.

• Earth-shaker: If no-GIL lands fully, true parallelism in CPython will change Python’s place in HPC and server workloads.
