+# Version 4.150.0
+
+> **Upcoming release** · In development · Not yet available on NuGet
+
+> **Supersedes [4.148.0](4.148.0-unreleased.md)** · Rolls up preview-only work that was never released as stable — those changes are included cumulatively below.
+
+## Highlights
+
+This in-development release cumulates all preview-only 4.148.0 work — including the Skia m148 engine upgrade, API surface refinements, and significant bug fixes — and adds harfbuzz 14.2.1 plus a containerized Tizen build environment on top of that foundation.
+
+## Breaking Changes
+
+*None in this release.*
+
+## New Features
+
+### Dependencies
+
+- **harfbuzz 14.2.1** — Updates the text shaping engine bundled inside Skia to the latest harfbuzz release. ([#4167](https://github.com/mono/SkiaSharp/pull/4167))
+
+### Platform
+
+- **Tizen builds in Docker** — Tizen native dependencies are now compiled inside a Docker container, improving build reproducibility and environment isolation. ([#4154](https://github.com/mono/SkiaSharp/pull/4154))
