			* [https://github.com/LuxCoreRender/BlendLuxCore/issues/167 Inserted keyframes in material node graph don't show up in graph editor or anywhere else]
			* LuxCore node parameters can not be animated in Blender 2.82. This bug is fixed in Blender 2.83 and later
			* Rendering with caches (e.g. PhotonGI, DLSC, Env. light cache) can lead to problems '''if border rendering is enabled'''. A workaround is to disable automatic radius estimation and setting the radius manually instead when using border rendering

			===New Features:===

			* Add twosided material node
			* New light group editor, now in the compositor for improved workflow: https://youtu.be/vqigKhwWxIs
			* Warn if subdiv modifier is enabled in viewport, but disabled in final render, or if the subdiv level in viewport is higher than in final render
			* Add support for non-uniform chromatic aberration
			* Add support for sinc and catmullrom filter
			* Move film device selection to properties, couple to GPU backend
			* Add support for OptiX denoiser for viewport renders
			* Add support for non-uniform bokeh and custom bokeh images
			* Show a more helpful error message for Windows 7 users missing the update needed for AddDllDirectory
			* Add stop button, to stop a render and run compositing
			* Add support for holdout material option (in material output node)
			* Add support for wireframe texture
			* Use the new eye/light halt spp conditions (this means that samples from light tracing are now separate, which makes it much easier to set halt spp correctly with light tracing enabled)
			* Improve volume node warning about incompatible (2D) texture nodes
			* Allow to set the volume ID
			* Add distort texture
			* Add support for new AOVs (separate reflect/transmit variants of diffuse/glossy/specular direct/indirect light AOVs, caustic AOV)
			* Cycles node reader: add support for the Normal input on material nodes, and basic support for the Bump node
			* Cycles node reader: add support for holdout shader
			* Add support for randomized tiling
			* Add support for "reverse" option of white balance imagepipeline plugin
			* Add support for temperature property of lights
			* Make it possible again to use different devices for viewport and final renders (default for viewport: CPU), because users might prefer the lower latency of CPU preview renders even when using the GPU for final rendering
			* Use sensible min value for Blender texture noise size
			* Add support for texture bombing node
			* Show a warning if an unsupported image source like Movie or UDIM Tiles is selected
			* Rename AOV panel from "LuxCore Arbitrary Output Variables (AOVs)" to "LuxCore AOVs"
			* LOL: Add support for local material assets and thumbnail rendering
			* LOL: Automatically copy and downscale full preview images placed in preview directory (e.g. by manual download)

			v2.5beta1 released

			* Expose bump sampling distance because it requires adjustment in some rare cases (e.g. in very large or very small scenes, when procedural textures with extreme frequencies of detail are used)
			* Add notes to tooltips that caches are only used during final render
			* Show warning if a material combines volumes with opacity < 1, as this can lead to artifacts
			* Add support for hiding planar edges in wireframe node
			* Add slower fallback for custom normals if they aren't supported through C++ for a Blender version (a warning is shown if this adds more than 0.3 seconds to the export time of a mesh, so the user can disable custom normals for the mesh if they are not needed and drive up export time too much)

			===Fixed Bugs:===

			* Fix message about env. light cache building showing in viewport render, even when the cache is not built
			* Fix NodeTreeUndefined being returned as node_tree.bl_idname in some cases
			* Fix wrong function return values on hair export failure
			* Fix NVRTC DLL loading on Linux
			* Hide non-functional camera stereoscopy panel
			* Cycles node reader: Fix bug with nested node groups
			* Brick texture: remove unused bevel option, rename sockets, add support for modulation bias property
			* Fix wrong sampler property being used when engine is Bidir and device is OCL
			* Set glossytranclucent backface props regardless if double sided is checked or not
			* Change Cauchy naming convention in Glass Material
			* Fix out of core being used for CPU if enabled for GPU
			* LOL: Fix wrong category asset selection
			* LOL: Fix bug with assetbar when asset count is smaller than max row count
			* LOL: Change colorspace of preview images from linear to default
			* LOL: Use low resolution thumbnails in assetbar
			* LOL: fix thumbnail download
			* LOL: Fix thread handling (start thread twice error) if an error occurs during execution
			* LOL: Fix bug in library deactivation in preferences which keep the LOL tab visible

			v2.5beta1 released

			* Fix crash on trying to replace a pinned node tree
			* Fix no viewport update being triggered when toggling the advanced options of velvet material
			* Fix dimension, lacunarity, octaves and intensity parameters of musgrave texture not working
			* Fix noise depth not working in blender marble texture
			* Fix RGB color and temperature not working for sun light and its sub-types (sun, distant, hemi)
			* Ensure that noisedepth aka oct is in range 0..25 to avoid visual artifacts
			* Fix a panel being shown even when the renderengine is not LuxCore
			* Implement a workaround for viewport sessions not being deleted after viewport window resize or render configuration change, which led to a memory leak
			* LOL: Fix problem of material assets if material name doesn't match asset name
