Vowpal Wabbit Versions Save

Vowpal Wabbit is a machine learning system which pushes the frontier of machine learning with techniques such as online, hashing, allreduce, reductions, learning2search, active, and interactive learning.

9.0.0

2 years ago

Vowpal Wabbit 9 is the first major release in over 6 years! There are a number of usability improvements, new reductions, bug fixes and internal improvements here. The Python package has undergone a bit of a modernization with a more understandable module structure, naming and types. Most changes should be non breaking for standard use cases. See here for the Python migration guide.

ci: update brew to mitigate bintray brownout (#2941)
chore: update version to 8.10.1
build: add 3.9 to windows python build (#2939)

Fixes

[nn] fix double free (#2802)

8.9.1

3 years ago

This patch release contains a fix for the Java bindings. It changes no other code paths apart from the version number changing.

Fixes

Don't export lib symbols from vw_jni binary when static linking (#2789)

8.9.0

3 years ago

This release includes major features such as continuous actions, square CB, probabilistic label tree, slates, CB distributionally robust optimization, CB ADF RND, Python wheels and many bug fixes.

This patch release fixes an issue in the Python bindings where parsing examples from text sometimes caused crashes.

Fixes:

Fix delete behavior for examples created using parse function (#2206)

8.8.0

4 years ago

There has significant work in streamlining and improving support for the Python bindings. Thanks @peterychang! (#1928)
The Conditional Contextual Bandit reduction got merged in, this reduction allows you to express problems where there are multiple slots to fill. See here for the wiki page. (#1816) (#1995) (#2078) (#2141)
CMake install targets have been added to the build files (#2172) (#2135)
- Now you can find and link VW easily in other projects:
```
find_package(VowpalWabbit REQUIRED)
add_executable(my_exe main.cpp)
target_link_libraries(my_exe PRIVATE VowpalWabbit::vw)
```
Slim VW got merged into master. This is an experimental lightweight inference runtime that supports a subset of VW features. (#2028)
Bug fixes! (see all changes below)
