 **PyKX** is a Python-first interface to **kdb+** (the world's fastest time-series database) and **q** (kdb+'s underlying vector programming language). PyKX is the result of 10+ years of integrations between two languages: Python and q. Its aim is to help users query and analyze huge amounts of in-memory and on-disk time-series data, significantly faster than other libraries.
 
+- For **Python developers**, PyKX unlocks the speed and power of kdb+ for data processing and storage from within your Python environment. It enables anyone with Python knowledge to apply analytics against vast amounts of data, both in-memory and on-disk, in a fraction of the time, allowing you to focus on getting the best from your data.
+
+- For **q developers**, PyKX brings together Python's data science ecosystem and the power of kdb+'s vector and time-series analytics. This makes them available in both q and Python environments. You can use it to run q code within a Python environment or embed Python analytics within your q session.

 ## Use cases
 
 PyKX supports three main use cases, allowing Python data engineers and data scientists to:

-# PyKX 3.1.8
+## PyKX 3.1.9
+
+#### Release Date
+
+2026-04-02
+
+### Additions
+
+- Added `.np()` method to `pykx.serialize` function, this returns the serialized data as a NumPy array.
+- Added support for calling `pykx.deserialize` on NumPy arrays of serialized `K` objects.
+
+	```python
+	>>> import pykx as kx
+	>>> vec = kx.q('til 10')
+	>>> vec
+	pykx.LongVector(pykx.q('0 1 2 3 4 5 6 7 8 9'))
+	>>> ser = kx.serialize(vec)
+	>>> type(ser)
+	<class 'pykx.serialize.serialize'>
+	>>> ser_np = ser.np()
+	>>> type(ser_np)
+	<class 'numpy.ndarray'>
+	>>> ser_np.dtype
+	dtype('uint8')
+	>>> kx.deserialize(ser_np)
+	pykx.LongVector(pykx.q('0 1 2 3 4 5 6 7 8 9'))
+	```
+
+- Added `.bin()` method to `pykx.Column` class, to perform a binary search using the data in a `pykx.Column` object.
+
+	```python
+	>>> import pykx as kx
+	>>> t = kx.q('([] n: 2 4)')
+	>>> t.select(kx.Column('n').bin([1,3,5]))
+	pykx.Table(pykx.q('
+	n
+	-
+	0
+	1
+	'))
+	```
+
+### Fixes and Improvements
+
+- Updated 4.1 to 2026.04.01 for all platforms.
