 -->
 
+1.8.18
+
+- fixed: remove the switch to "bg_cam" (when exists) in autobuild
+
+1.8.17
+
+- changed: in autobuild, skip object that are not visible in scene or with render toggle off
+
+1.8.16
+
+- fixed: Better reorder socket. Still not perfect, can have bad result if there some unconnected sockets on both sides.
+
+1.8.15
+
+- changed: exclude background GP by default in autobuild (`is_background` is a custom property set on some GP by the addon "Background Plane Manager")
+- added: autobuild bool argument `exclude_background_gp` (Default to True).
+- fixed: clean name in file output gernerator
+
+1.8.14
+
+- fixed: error when trying remove a viewlayer
+
+1.8.13
+
+- changed: improve `connect to fileoutput` feature:
+  - possible to choose `node_name + socket name` or `node name` instead of `socket name` only
+  - default is now `node_name_socket_name`
+  - added some exception behavior:
+    - if a node has single output : write the node name only
+    - render layers use `scene_viewlayer` as node_name intead of "Render Layer"
+    - interface shows source node label (with source node name in parenthesis)
+    - interface shows render layer scene/viewlayer name (with name in parenthesis)
+
+- fixed: a potential name overlapping bug in connect to fileoutput
+
+1.8.12
+
+- changed: Use GP_RENDER_FILE_FORMAT env var to set file output nodes
+
+1.8.11
+
+- fixed: cleaning materials duplication checked against name without checking material GP type
+
+1.8.10
+
+- fixed: node not deleted after a merge using (compo scene not referenced correctly to point node_trees)
+
+1.8.9
+
+- fixed: error when setting object active at the end of autobuild
+
+1.8.8
+
+- added: Add `export transformation to AE` in export menu:
+ - export camera
+ - export objects transformation 
+ - export exposition (object, GPencil keys, etc)
+
+1.8.7
+
+- changed: Layer `channel_colors` have _value component_ clamped to 0.65 when transfered to compo node to limit color flashyness (eye care update)
+
+1.8.6
+
+- changed: removed mask terms from exclude export list `MA, MASK, mask, MSK, msk` (still excluded when opacity is at 0)
+
+1.8.5
+
+- changed: `group adjacent prefix` prefix pattern now ignore case
+
+1.8.4
+
+- fix: select node from layer
+- changed: Check for problems: object numbering check does not list as error if parent part has number prefix (previously checked only for last part)
+
+1.8.3
+
+- changed: for layer with 0 opacity, do not send to render and keep opacity
+- removed: `GP` prefix exclusion to send GP to render
+- added: more default prefix exclusion for _layer to render_ and _skip opacity reset_ (`MASK, mask, MSK, msk`)
+- added: option to restore layer state from json (commit by Christophe.S)
+
+1.8.2
+
+- added: `Reset Layer State` (Check layer) in Autobuild
+- added: environment variable `GP_RENDER_LAYER_GROUP_PATTERN` for layer merging regex pattern
+
