 # @debuffjp/core
 
+## 0.34.0
+
+### Minor Changes
+
+- 8784a2c: `GameOptions.blendSpace` passes spryte's `blendSpace` to the renderer, so a debuff game can turn on linear-light blending with `new Game({ ..., blendSpace: "linear" })`. Before this, `Game` created the renderer with only `backend` and `smooth`. Reported in #112.

 # spryte
 
+## 0.16.0
+
+### Minor Changes
+
+- 8784a2c: `source(uv)` in custom shaders now takes a `highp` uv, as do spryte's built-in effect and blur. Shaders run under `precision mediump float`, so before this a texture read through `source()` was addressed at fp16 on many mobile GPUs and sampled the wrong texels in images past about 1024 px, whatever precision the effect declared. The documented signature is now `vec4 effect(vec4 color, highp vec2 uv)`; an unqualified `vec2 uv` still compiles but stays mediump. Reported in #110.
+- 8784a2c: `Shader.set()` with the value a uniform already has no longer ends the batch. Numbers and arrays compare by value; a texture, or the same array object passed again (its contents may have changed), still flushes. The Shader docs now say that a shader switch and a uniform change each end a batch, and show the pattern for per-sprite values: one `withShader` around the whole walk. Reported in #109.
+- 8784a2c: `source()` in custom shaders picks the batch's texture with a `switch` instead of a chain of eight `if`s. A 16-tap effect over eight textures took about 35% less frame time on an RTX 5060 (7.1 ms to 4.6 ms median for 32 full-HD layers), with the same pixels. One-tap effects, including spryte's default program, showed no measurable change. Reported in #111.
+- 8784a2c: `draw.sprite` takes `user` and `user2` options: two floats a custom shader reads as `user()` and `user2()`, as `draw.sprites` copies already could through `each`. The sprite stays in the batch, so a per-sprite parameter (a share, a variant, a flag) no longer has to be packed into the tint. Sprites that set neither read 0. The values travel in a separate buffer that is uploaded only for a batch that uses them, so draws without a custom shader don't change. `spriteOptions()` includes the two new fields. Reported in #113.
+- 8784a2c: `asData(image, { premultiply: false })` uploads an image with straight alpha, under either blend space, so data packed into RGBA (timings, indices) survives where alpha is below 255. Other images still upload premultiplied. It works for an `<img>`; a canvas already holds premultiplied pixels, and an `ImageBitmap` keeps the `premultiplyAlpha` it was made with. Reported in #112.
+
+### Patch Changes
+
+- bed271b: A render target refilled with `draw.into()` after it was drawn stays filled. Its texture could still be bound to a texture unit from the earlier draw (or from its own creation), so the next draw into it was a feedback loop: WebGL rejected it and logged `GL_INVALID_OPERATION ... Feedback loop formed between Framebuffer and active Texture`, and the target stayed blank. Switching to a target now rebinds the 8 sprite units first. The same loop hit frames of shapes only under `blendSpace: "linear"`, whose sRGB framebuffer texture stayed bound after `end()` presented it; it no longer does. Reported in #118.
