+## [0.29.0] — 2026-08-05
+
+RISC-V GOOBJ emission, YMM vector register display, named buffer allocation
+in the debugger, two new CLI commands (`diff`, `profile`), go-to-definition in
+the LSP, combined ABI+fuzz verification, and did-you-mean label suggestions.
+
+### Added
+
+- **RISC-V GOOBJ emission** — `gasm asm --format goobj` for RISC-V produces
+  linkable Go objects with funcdata, pc-value tables, and RISC-V relocation
+  types (same format as amd64 GOOBJ, with the RISC-V architecture marker).
+- **`gasm diff`** — compare the machine code of two assembly files byte-for-byte;
+  shows which functions differ and the first few differing bytes.
+- **`gasm profile`** — show the basic-block structure of each function: labels,
+  offsets, frame size, and NOSPLIT flag.
+- **LSP go-to-definition** — `textDocument/definition` navigates from a label
+  reference to its definition.
+- **did-you-mean** — when the RISC-V assembler encounters an undefined label, it
+  suggests the closest existing label using Levenshtein distance.
+- **YMM vector register display** — `regs` in the debugger now shows YMM
+  registers via `PTRACE_GETFPREGS` (falls back to XMM when XSAVE is unavailable).
+- **Named buffer allocation** — `gasm debug --buf name:size:pattern` allocates
+  buffers in the debuggee filled with `zero`, `ones`, `seq`, or a hex pattern;
+  buffer pointers are placed into the argument block at the matching positions.
+- **Crash input storage** — `FuzzResult.CrashInput` stores the input that caused
+  a crash or mismatch for reproducibility.
+- **ABI + fuzz combined** — `gasm verify --fuzz` now runs ABI checks (sentinel
+  registers, canary, stack bounds) alongside differential fuzz testing.
+
+### Verified
+
+- RISC-V GOOBJ output links correctly with the Go toolchain.
+- `gasm diff` detects byte-level differences in real assembly kernels.
+- LSP go-to-definition resolves labels across functions and files.
+- Debugger YMM display confirmed on AVX2-capable hardware.
