 # Release notes
 
+## 1.2.6 (versionCode 8)
+
+Presets
+- New film sim B&W HIGH CONTRAST, next to ACRIPES. Acros' grey ramp taken through a warm filter mix - red 0.38 / green 0.56 / blue 0.06, the three rows equal and summing to 1.00, so a neutral stays the neutral the sensor recorded and nothing clips at either end - and then pushed at both ends: the toe goes to -0.32 against Acros' -0.12, and the shoulder LIFTS to +0.26 instead of rolling off. Midtones see neither mask, so the long smooth stretch between the two ends survives, which is what keeps that hard a push off the posterised look.
+- The stock's own slope (+4 of Contrast) is not in the sim's adjustments: the panel still reads EXPOSURE 0 / CONTRAST 0, and FX still reads GRAIN 0 / CLARITY 0, while the render comes out pushed. It rides STOCK_BIAS in colorUtils.ts, keyed by baseFilter - the old STOCK_EXPOSURE table folded in, one place for the tone a stock carries by itself (LC STREETLIFE VIVID exposure +2, B&W HIGH CONTRAST contrast +4).
+- Two black-and-white stocks exist now, so every "is this a colour stock?" test goes through the new isMonochromeBase(): saturation, white balance and the R/B fine-tune in the matrix, Color Chrome in the tone shader. A second B&W stock can no longer end up half excluded - a stray Kelvin gain on a grey ramp shows up as a tint.
+- Measured against the compiled tables: a 0.25 grey goes 0.2500 -> 0.2250 (the +4 slope pivoting on mid-grey 0.5), a full red goes 0.213 -> 0.368 while blue drops to 0.016, and colour-stage knobs moved hard (saturation +8, white balance 9000K, wbR +5 / wbB -5) leave both B&W matrices byte-identical.
+- On a Xiaomi thor: the chip sits right after ACRIPES, its preview reads mean chroma 0.00 against 17.48 for a colour sim, and the frame's luma spread widens as designed (sd 92.3 / p95 245 against ACRIPES' 88.9 / 238).
