+# v0.9.3 - 2024-09-30
+
+## Breaks
+- `PyComplex[T]` -> `PyTComplex[T]`; PyComplex is now non-generics (like CPython's `Py_complex`)
+
+## Bug fixes
+- Lib/pathlib: argument order of Path.{sym,hard}link_to was reversed
+- os.utime not compile on x86_64 macos
+
+### math
+- expm1, log1p was inaccurate for arg near 0
+- dist's signature was wrong ( used to be `func [F: SomeFloat](x, y: F): F` )
+- `degrees` was typed as `degress`
+- log1p, expm1 not accurate for arg near 0; 
+
+
+## Fixes for inconsistence with Python
+- math.{floor,ceil,trunc} now return int over float
+- str for complex(N, nan) was "(Nnanj)" (shall be "nanj") and str(complex) returns something in form of `Complex(re: A, im: B)`
+- Lib/math's functions raises exception as Python does when math error occurs
+- Lib/math:
+  - dist's signature wrongly used that of hypot
+  - `degrees` was typed as degress
+
+## Feature additions
+- pow for complex type
+
+
+### math
+- supports objc (not test yet)
+- supports compiletime (nimvm)
+- for JS:
+  - math
+    - gamma, lgamma, erf, erfc are supported
+    - ldexp is more accurate
+
+- math:
+  - cbrt
+  - sumprod, dist, hypot
+  - nextafter, ulp
+  - ...  (all APIs in CPython's math)
+
+- pathlib:
+  - `/=` for Path
+
