16+ - Fix a bug in :class: `~imblearn.over_sampling.SMOTENC ` where the entries of the
17+ one-hot encoding should be divided by `sqrt(2) ` and not `2 `, taking into account that
18+ they are plugged into an Euclidean distance computation.
19+ :pr: `1014 ` by :user: `Guillaume Lemaitre <glemaitre> `.
20+
21+ - Raise an informative error message when all support vectors are tagged as noise in
22+ :class: `~imblearn.over_sampling.SVMSMOTE `.
23+ :pr: `1016 ` by :user: `Guillaume Lemaitre <glemaitre> `.
24+
25+ - Fix a bug in :class: `~imblearn.over_sampling.SMOTENC ` where the median of standard
26+ deviation of the continuous features was only computed on the minority class. Now,
27+ we are computing this statistic for each class that is up-sampled.
28+ :pr: `1015 ` by :user: `Guillaume Lemaitre <glemaitre> `.
29+
30+ - Fix a bug in :class: `~imblearn.over_sampling.SMOTENC ` such that the case where
31+ the median of standard deviation of the continuous features is null is handled
32+ in the multiclass case as well.
33+ :pr: `1015 ` by :user: `Guillaume Lemaitre <glemaitre> `.
34+
35+ - Fix a bug in :class: `~imblearn.over_sampling.BorderlineSMOTE ` version 2 where samples
36+ should be generated from the whole dataset and not only from the minority class.
37+ :pr: `1023 ` by :user: `Guillaume Lemaitre <glemaitre> `.
38+
1639- Fix a bug in :class: `~imblearn.under_sampling.NeighbourhoodCleaningRule ` where the
1740 `kind_sel="all" ` was not working as explained in the literature.
