 # Changelog
 
+## [16.4.0] - unreleased
+
+### General
+- Officially added support for Python 3.13.
+
+### Removed
+- The deprecated functions `Game.read_game`, `Game.parse_game` and `Game.write` functions have
+  been removed as planned. (#357)
+
+### Added
+- Implement `GetPlays()` (C++) and `get_plays` (Python) to compute the set of terminal nodes consistent
+  with a node, information set, or action (#517)
+- Implement `GameStrategyRep::GetAction` (C++) and `Strategy.action` (Python) retrieving the action
+    prescribed by a strategy at an information set
+- Tests for creation of the reduced strategic form from an extensive-form game (currently only
+  for games with perfect recall)
+- Implement `Nodes` collection as a member of `GameRep`, including a C++ iterator that
+  returns nodes in depth-first traversal order (#530)
+
+
+## [16.3.1] - unreleased
+
+### Fixed
+- Corrected a regression in which information sets were prematurely invalidated (and therefore
+  `delete this` called on them) when removing the last node from an information set.
+
+
+## [16.3.0] - 2025-01-13
+
+### General
+- Dropped support for Python 3.8.
+
+### Added
+- Implemented maximum-likelihood estimation for agent logit QRE, to parallel existing support
+  for strategic logit QRE.  Strategic logit QRE function names have been modified to provide
+  parallel naming.  Estimation using the correspondence now supports an option to stop at the
+  first interior local maximizer found (if one exists).
+- Maximum-likelihood estimation for logit QRE using empirical payoffs has an improved internal
+  calculation of log-likelihood, and returns the estimated profile instead of just a list of
+  probabilities.
+- Reorganized naming conventions in pygambit for functions for computing QRE in both strategic
+  and agent versions, and added a corresponding section in the user guide.
+- `enumpoly_solve` has been returned to being fully supported from temporarily being experimental;
+  now available in `pygambit`.
+- `enumpoly_solve` for strategic games now uses the Porter, Nudelman, and Shoham (2004) ordering
+  of supports to search.
+- `to_arrays` converts a `Game` to a list of `numpy` arrays containing its reduced strategic form.
+  (#461)
+- Integrated support (in Python) for using `PHCpack` to solve systems of polynomial equations in
+  `enumpoly_solve` based on an implementation formerly in the `contrib` section of the
+  repository. (#165)
+- New format-specific functions `pygambit.read_*` and `pygambit.Game.to_*` functions have been
+  added to (de-)serialise games.  The existing `Game.read_game` and `Game.write` functions have
+  been deprecated and will be removed in 16.4. (#357)
+
+### Changed
+- The built-in implementation of lrslib (dating from 2016) has been removed.  Instead, access to
+  lrsnash is provided as an external tool via the `enummixed_solve` function, in parallel to
+  PHCpack for `enumpoly_solve`.
+
+### Fixed
+- When parsing .nfg files, check that the number of outcomes or payoffs is the expected number,
+  and raise an exception if not.  (#119)
+
+### Removed
+- `Game.write()` no longer supports generation of the XML-format files for Game Theory
+  Explorer, as GTE no longer reads files in this format.
+
+
 ## [16.2.2] - unreleased
