 Changelog
 =========
 
+Version 0.1.4
+-------------
+
+Density placement: Force scaling on voxels that are not full. Fix #27. (#28)
+
+split_into_halves existed in atlas_commons; remove the copy here (#26)
+
+Restrict ISH slice positions that are inside the volume_mask volume. (#25)
+
+Version 0.1.3
+-------------
+Add excitatory split
+
+Version 0.1.2
+-------------
+
+Excitatory split (#19)
+ * Write SSCX layer-specific types to all isocortex
+ * Changed layer key in csv file, changed layer filter in metadata to make it specific for Isocortex layers, changed code to do isocortex instead of just SSCX
+ * made it isocortex specific
+ * Used code snippet from Dimitri to read in metadata and create layers
+
+Version 0.1.1
+-------------
+
+Update Roussel et al.'s pipeline to match implementation from the paper (#12)
+ * Update Roussel et al.'s pipeline to match the implementation from the paper. Htr3a is now split into vip and lamp5.
+ * Added a warning for the user in case the thresholding causes the dataset to be entirely null.
+ * A threshold can be applied to the Nissl and raw ISH datasets to remove a part of the background expression.
+  If the expression outside the test datasets is too high then the thresholding process will set the whole dataset to 0. Some tests will therefore randomly fail when this event happen.
+
+add examples to README.rst (#6)
+ * Add references to Rodarie's and Roussel's and Kim's paper.
+ * Add context for the AIBS datasets and pipeline steps.
+ * add note about memory usage
+ * Fix assertion errors due to float rounding issues for inhibitory neuron density optimization.
+
+Fixes to match previous pipeline
+ * Split mandatory ccfv2 fibers and cell containing regions combination from ccfv3 / ccfv2 annotation combination
+ * Add normalization and cell overlapping of Nissl and ISH dataset to match Erö's pipeline.
+ * Fix glia cell density placement, prevent negative densities.
+ * Add purely inhibitory regions for Erö's method to match model from 2019.
+ * Fix masks for cerebellar cortex, molecular and cortex L1 and related test.
+
+
+fix warnings/deprecations (#5)
+
