The format is based on Keep a Changelog.

This project adheres to a flavour of Calendar Versioning
for the globale releases (YYYY.MINOR), and to Semantic
Versioning for libnopegl.

[Unreleased]

[2023.4] [libnopegl 0.10.0] - 2023-09-28

Added

• Eval* nodes now accept multi-dimensional input resources
• luma(r,g,b) and srgbmix(a,b,x) functions in eval
• GridLayout node to make a grid out of a number of scenes
• FilterColorMap node to remap colors using a gradient of color points
• Animated GIF export in the viewer
• RenderNoise node to generate fractal noise on the GPU
• Texture2D node now accepts a scene as data_src and acts as an implicit
  render target (which simplifies the graph when all the features of the
  RenderToTexture node are not needed)
• RenderToTexture and Texture2D nodes can now be automatically resized to
  match screen size if their initial dimensions are left to (0, 0)
• Ability to drag'n drop Python scripts in the Viewer

Fixed

• Viewer path management on Windows
• Name filters in the export dialog of the viewer
• Viewer export on Windows

Changed

• The installed nodes.specs specifications have been extended to include more
  information (types, choices, etc)
• The documentation has been reworked, notably to include code examples with
  associated rendering and graph
• Transform node now accepts a node as input parameter and can be animated
  this way
• scene, SceneInfo and SceneCfg are now part of pynopegl instead of
  pynopegl-utils, where they are deprecated

Removed

• RenderToTexture.features as the RTT node is now able to detect
  automatically if the underlying graph requires a depth/stencil buffer

[2023.3] [libnopegl 0.9.0] - 2023-09-01

Fixed

• Linux and macOS release jobs

[2023.2] [libnopegl 0.9.0] - 2023-09-01

Added

• Much more detailed typing annotations in pynopegl
• RenderDisplace node for texture displacement
• Visual scopes support through the ColorStats, RenderHistogram and
  RenderWaveform nodes (see scopes example in the demos)
• Multiple modulo functions for the Eval* nodes: mod_e (euclidean), mod_f
  (floored) and mod_t (truncated)
• Support for rendering to 3D textures
• Support for 3D textures image load/store
• Support for cube maps image load/store
• Support for array of 2D textures
• External font rendering in the Text node
• Fixed scaling in the Text node
• Text effects (color, opacity, transform, glow, outline, blur), applicable per
  character/word/lines
• PathKeyClose node to close the current sub-path
• RenderPath node to render paths visually
• Optional compat_specs in the @scene decorator to add a version requirement
  constraint
• ngl-viewer tool to select, customize and export scenes with a simple and
  intuitive interface

Changed

• CSV export in the HUD now always prints floats in C locale instead of quoted
• pynopegl.Context.configure() now takes a Config as argument
• pynopegl log levels are now controled using the pynopegl.Log enum
• max_texture_dimensions_* capabilities are renamed to max_texture_dimension_*
• Backend probing in pynopegl now returns a more Pythonic output
• GraphicConfig.scissor is now an ivec4 parameter instead of vec4
• TimeRangeMode* nodes are removed and TimeRangeFilter is simplified to
  handle their role; if multiple ranges are needed simulteanously, a Group can
  be used. TimeRangeFilter.max_idle_time is removed since its use was limited
  to inter range times (now only a single time segment is handled).
• The API now mandates that node scenes have to be wrapped into a dedicated
  scene object that holds extra metadata (duration, aspect ratio and framerate)
• All counters and size-based arguments in the public API are now using size_t
  instead of int
• The Text.valign and Text.halign parameters now also align the text per line
• Text rendering has been completely reworked to support more advanced effects
  and smooth rendering at high resolution
• The @scene decorator now relies on an explicity controls dictionary
  instead of **kwargs
• The Texture* nodes now use linear filtering by default instead of
  nearest

Removed

• ResourceProps.variadic bool flag as it was never a functional interface
• NGL_CAP_NPOT_TEXTURE as we mandate full support for textures with
  non-power-of-two dimensions
• Support for OpenGL < 3.3 and OpenGL ES < 3.0 and the associated capabilities:
  NGL_CAP_BLOCK, NGL_CAP_INSTANCED_DRAW, NGL_CAP_SHADER_TEXTURE_LOD,
  NGL_CAP_TEXTURE_2D_ARRAY, NGL_CAP_TEXTURE_3D, NGL_CAP_TEXTURE_CUBE,
  NGL_CAP_UINT_UNIFORMS
• GLSL ngl_tex{2d,3d,cube,2dlod,3dlod,cubelod}() declarations (users must now
  use texture() and textureLod() directly). ngl_texvideo() is still there
  and is still the prefered picking method

[2023.1] [libnopegl 0.8.0] - 2023-04-07

Changed

• Project renamed to nope.gl, as part of the Nope Foundry

---

  environments)
• Compatibility with static analyzers for symbols discovery in pynodegl,
  including typing annotations
• Compatibility with Vulkan devices not supporting host cached memory

Fixed

• Missing exposed constants in pynodegl (some backend capabilities and
  the Wayland platform ID)
• Undefined behaviour when using geometries with Render* nodes (Render node
  is not affected)
• Undefined behaviour in sRGB/linear conversions with negative colors

Changed

  of an integer index

Added

• eye, center and up Camera parameters can now be node
• Honor NO_COLOR environment variable

Fixed

• A crash happening in the VAAPI context module when both the OpenGL and Vulkan
  backends were enabled.
• A deadlock in ngl-control when specifying invalid encoding arguments
