+<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 dev@mahout.apache.org 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>

-
- <ul>
- <li>Improved Lanczos solver: graceful restarts, better scalability</li>
- <li>LDA improvements: document-topic distribution output, graceful restarts</li>
- <li>Stochastic Singular Value Decomposition implementation</li>
- <li>Incremental SVD implementation</li>
- <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>
- <li>Significant removal of deprecated or dead code</li>
- <li>Many bug fixes, refactorings and other small improvements</li>
