JIRA ID: ALMIOPEN-2636

Motivation

Routine version bump for the ROCm 10.2 release.

Technical Details

Bumps MIOpen from 3.6.1 to 3.6.2 in CMakeLists.txt and adds the corresponding entry to CHANGELOG.md.

Risk Assessment

Mechanical version-number change only; no code or behavior affected.

Risk Level: 🟢 Low

Test Plan

None needed — versioning/changelog metadata only.

Test Result

N/A.

JIRA ID: ALMIOPEN-2913

## Motivation

Only 5 of the 30 commits that landed against `projects/miopen` since the
3.6.2 version bump (`2d20a8f775e`, #12211) were reflected in
`CHANGELOG.md`. The remaining 25 were reviewed and the 15
externally-visible ones documented, so the ROCm 10.2.0 section
accurately reflects what shipped.

14 entries added (two of the fixes share one entry), plus a
duplicate-heading fix.

### Added
* [Conv] NHWC (channel-last) support in the GEMM convolution solvers,
with new im2col/col2im kernels (#8693)
* [Conv] Cross-architecture AI heuristics for immediate mode
(`MIOPEN_FIND_MODE=2`), extending data-driven selection to Navi (#9680)
* [Conv] Missing 3x3 stride-1 pad-1 tile-28 CK depthwise backward-data
instance — ALMIOPEN-2423 (#11271)

### Changed
* [Conv] `ConvHipConv` held out of the AI perf-config picker until its
model is retrained — ALMIOPEN-2494 (#13337)
* [Conv] CK byte-span gate lifted for forward and backward-data, now
that CK fixes the 32-bit offset overflow itself — ALMIOPEN-2645 (#12396)

### Optimized
* [Conv] `ConvDirectNaiveConv`: per-direction kernel files, float
accumulators, spatial tiling, bfloat16 path — ALMIOPEN-2485/2486 (#7529)
* Kernel cache reuses cached SQLite connections instead of reopening per
load/store — ALMIOPEN-2598 (#11933)

### Resolved Issues
* [Conv] Incorrect backward-weights results from the gfx950 direct
kernel at `waves_q == 1` (missing cross-lane ordering on LDS staging
reuse) — ROCM-31508 (#12406)
* [Conv] Up to 8x slower hipconv `direct`/`direct_l1`/`direct_wgrad`
under ROCm 10.1's full AMDGCN LTO default; fixed with `-fno-offload-lto`
— ROCM-31334 (#12328)
* [Conv] gfx942 multi-node training throughput regression from backward
GEMM on small-batch 1x1 NHWC shapes — ROCM-31155 (#13232)
* [Conv] Invalid CK perf-config entries in the gfx1201 and gfx1100
system databases — ROCM-29026 (#12088, #12117)
* [BatchNorm] JIT compilation failures on non-GFX9 targets; Welford DPP
assembly restricted to GFX9 — ALMIOPEN-2838 (#12889)
* Out-of-bounds write in `miopenLoadSolution` when a serialized solution
carries more than three work dimensions — ROCM-31082 (#12242)
* `uint64_t` typedef conflict between `miopen_cstdint.hpp` and system
`<stdint.h>` on LP64 Linux (#12623)

## Technical Details

Single-file change to `projects/miopen/CHANGELOG.md`.

The 10.2.0 section had **two** `### Resolved Issues` headings. The two
entries under the trailing one (`ConvHipConv` gfx1250 crash/LDS race,
and the perf-db reload config loss) were merged into the first, and the
trailing heading removed — this accounts for the 2 removed bullets in
the diff. Section order is now `Resolved Issues → Added → Changed →
Optimized → Removed`, matching the 3.6.1 section. `Optimized` is new to
this release section.

Already documented, so untouched: #12874 (reduce int32 rejection),
#12000 / #13016 / #13213 (hipconv v0.3.1 / v0.3.2 / v0.4.0), #11761
(gfx803 removal).

## Notes

Deliberately excluded as not externally visible (10 commits):

* **hipDNN convolution forwarding (#12276)** —
`MIOPEN_ENABLE_HIPDNN_WRAPPER` defaults to `OFF`
(`projects/miopen/CMakeLists.txt:162`), so no shipped build compiles the
forwarding code and the runtime `MIOPEN_HIPDNN_FORWARDING` flag has
nothing to enable.
* **Test-only**: #13289 (gfx1250 depthwise test applicability,
ALMIOPEN-2841), #11610 (hipDNN parity harness), #12660 (Jenkins status
post).
* **Internal kernel-math cleanup, generated ISA unchanged**: #13312
(drop direct `__ocml` calls), #13190 (remove broken single-argument
`__half` overloads).
* **Add/revert pairs, net no change**: #12466 + #13066 (gfx1101 Navi
system DBs), #12496 + #12800 (gfx1250 in the dev image arch lists).

## Risk Assessment

Documentation-only change to a single Markdown file; no code, build, or
runtime impact.

**Risk Level: 🟢 Low**

## Test Plan

None required — Markdown-only. Verified that the entry topics are not
already documented elsewhere in the file, that no content was lost when
merging the duplicate heading, and that every new entry maps to a commit
in `2d20a8f775e..origin/develop -- projects/miopen`.

## Test Result

16 bullets added, 2 relocated — 14 net-new entries covering 15 commits.
Duplicate heading removed; section ordering matches 3.6.1.
