+<p>FUTURE PLANS</p>
+
+<p>0.9</p>
+
+<p>As the project moves towards a 1.0 release, the community is working to
clean up and/or remove parts of the code base that are under-supported or that
underperform as well as to better focus the energy and contributions on key
algorithms that are proven to scale in production and have seen wide-spread
adoption. To this end, in the next release, the project is planning on
removing support for the following algorithms unless there is sustained support
and improvement of them before the next release.</p>
+
+<p>The algorithms to be removed are:</p>
+<ul class="alternate" type="square">
+ <li>From Clustering:<br/>
+ Dirichlet<br/>
+ MeanShift<br/>
+ MinHash<br/>
+ Eigencuts</li>
+ <li>From Classification (both are sequential implementations)<br/>
+ Winnow<br/>
+ Perceptron</li>
+ <li>Frequent Pattern Mining</li>
+ <li>Collaborative Filtering<br/>
+ All recommenders in org.apache.mahout.cf.taste.impl.recommender.knn<br/>
+ SlopeOne implementations in org.apache.mahout.cf.taste.hadoop.slopeone
and org.apache.mahout.cf.taste.impl.recommender.slopeone<br/>
+ Distributed pseudo recommender in
org.apache.mahout.cf.taste.hadoop.pseudo<br/>
+ TreeClusteringRecommender in
org.apache.mahout.cf.taste.impl.recommender</li>
+ <li>Mahout Math<br/>
+ Lanczos in favour of SSVD<br/>
+ Hadoop entropy stuff in org.apache.mahout.math.stats.entropy</li>
+</ul>
+
+
+<p>If you are interested in supporting 1 or more of these algorithms, please
make it known on [email protected] and via JIRA issues that fix and/or
improve them. Please also provide supporting evidence as to their
effectiveness for you in production.</p>
+
+<p>1.0 PLANS</p>
+
+<p>Our plans as a community are to focus 0.9 on cleanup of bugs and the
removal of the code mentioned above and then to follow with a 1.0 release soon
thereafter, at which point the community is committing to the support of the
algorithms packaged in the 1.0 for at least two minor versions after their
release. In the case of removal, we will deprecate the functionality in the
1.(x+1) minor release and remove it in the 1.(x+2) release. For instance, if
feature X is to be removed after the 1.2 release, it will be deprecated in 1.3
and removed in 1.4.</p>

- <li>Alternating Least Squares with Weighted Regularization collaborative
filtering implementation,
- both distributed and non-distributed</li>
- <li>SVDRecommender enhancements</li>
- <li>Initial work at merging clustering and classification
infrastructure</li>
- <li>Better control over candidate item selection in item-based
recommenders</li>
