+## [0.33.0] — 2026-09-14
+
+### Added
+
+- **Stack-split guards in `gasm asm`.**  Every framed function now gets
+  the morestack prologue check and the trailing morestack block
+  (`CALL runtime.morestack_noctxt`), byte-identical to the toolchain's
+  `stacksplit` output on all four architectures: the small, medium and
+  big frame classes, auto-NOSPLIT leaves, the materialised constants of
+  large frames (arm64 `R27`, riscv64 `X31`, loong64 `R30`) and the
+  arm64 extrasize rule.  Assembled objects are therefore linkable for
+  split functions, not only `NOSPLIT` leaves.
+- **`gasm dis`.**  Standalone disassembly through `golang.org/x/arch`:
+  a `.s` file is assembled and listed per `TEXT` function with local
+  labels at their real offsets, or raw bytes from a file or stdin are
+  disassembled linearly (`-a` selects the architecture).  The debugger
+  shares the same decoder instead of carrying its own.
+- **`gasm fmt -l` and `-d`.**  Check mode lists files whose formatting
+  differs; diff mode prints a unified diff from the project's own
+  LCS-based differ, with GNU header semantics.
+- **LSP cross-file navigation.**  Go-to-definition and find references
+  fall back from local labels to the `TEXT` functions of every open
+  document, and rename follows the same cross-file matching.
+- **Large frame offsets on riscv64 and arm64.**  Frame-relative loads
+  and stores beyond the signed 12-bit immediate range materialise the
+  address through the toolchain temp register (riscv64 `X31`, arm64
+  `R27`) instead of silently truncating the offset (riscv64) or
+  rejecting the instruction (arm64); arm64 frame sizes now add the
+  toolchain's extrasize exactly (+8 when the frame leaves an alignment
+  gap, +16 when it is already aligned).
+- **Tail calls `JMP sym(SB)`** on all four architectures (amd64 `E9`,
+  arm64 `B`, riscv64 `JAL X0`, loong64 `B`) with the call relocation.
+- **Live oracle-parity tests.**  Kernel files covering every guard
+  class, large-offset pattern and tail call are assembled by gasm and
+  by the installed `go tool asm` and compared byte-for-byte on all four
+  architectures, alongside the existing pinned-byte tests.
+
+### Fixed
+
+- The v0.32.0 review findings: the parser rejects malformed `TEXT`
+  frames and parses signed frame sizes; amd64 frame adjustments above
+  127 bytes encode with imm32; arm64 and loong64 relocation encodings
+  match the toolchain; the linter guards unnamed `TEXT` directives and
+  refreshes its textflag table; the LSP recovers from handler panics
+  and decodes client URIs; watchpoint slot state moved into the debug
+  session; dead verify code removed; em and en dashes replaced across
+  sources.
+- `gasm asm --format goobj`: internal calls to `TEXT` symbols of the
+  same file resolve on every architecture (the reference check accepted
+  only the amd64 call kind).
+- `gasm asm --format elf` on loong64: branch relocations now map to
+  `R_LARCH_B26` instead of falling into `R_LARCH_PCALA_HI20`.
+- arm64 large-prologue `ADD`/`SUB` use the extended-register encoding
+  the toolchain picks, and the morestack block saves the link register
+  with the toolchain's `OR` form on loong64.
