+VERSION 2.4.0
+
+2025-07-21
+	Forthcoming Breaking Change.  Support for Python 2 and Pythons <= 3.8 to be dropped.
+	* PyShp 2.4.0 is the latest (and likely last) version of PyShp to support Python 2.7 and Pythons <= 3.8.
+	  These CPython versions have reached [end of life](https://devguide.python.org/versions/#versions).
+	* Future development will focus on PyShp v3.0.0 onwards (currently intended to supporting Pythons >= 3.9).
+	* This will not break any projects, as pip and other package managers should not install PyShp 3.0.0
+	  (after its release) in unsupported Pythons.  But we no longer promise such projects will get PyShp's latest
+	  bug fixes and features.
+	* If this negatively impacts your project, all feedback about this decision is welcome
+	  on our [the discussion page](https://github.com/GeospatialPython/pyshp/discussions/290).
+
+
+	New Features:
+	* Reader.iterRecords now allows start and stop to be specified, to lookup smaller ranges of records.
+	* Equality comparisons between Records now also require the fields to be the same (and in the same order).
+
+	Development:
+	* Code quality tools (Ruff format) run on PyShp
+	* Network, non-network, or all doctests selectable via command line args
+	* Network tests made runnable on localhost.
