The symlink `archive/ktransformers/ktransformers` points to
`/home/djw/py311_717/ktransformers/ktransformers`, an absolute path
on a developer's local machine. It was introduced in #1581 during the
repository restructuring and is broken on every other machine.
Tools that recursively copy the repo tree (e.g. shutil.copytree)
fail with FileNotFoundError on this dangling link.
* Add utility script to merge loose layer weights to safetensors
* Send warnings and errors to stderr
* Fix expert index parsing for MOE_INT4 and MOE_INT8
* Support for GLM-5 and Minimax-M2.5
Add CPU weight conversion support for GLM-5 and Minimax-M2.5
* fix: remove overly restrictive MiniMax condition and deduplicate code
- Remove `args.input_type == "fp8"` from MiniMaxConverter selection so
bf16/fp16 MiniMax models no longer fall through to OnlineQuantConverter
(which doesn't handle w1/w2/w3 naming and would fail).
- Remove OnlineQuantConverter._find_expert_layers() which is identical
to the inherited ConverterBase._find_expert_layers().
- Remove redundant expert_key_filter assignment (same as base default).

Add numa_nodes parameter to BaseMoEWrapper and all subclasses, allowing
users to explicitly specify which NUMA node IDs to use for subpool
mapping instead of always defaulting to sequential [0, 1, ..., N-1].
This enables running multiple KTransformers instances on different NUMA
nodes of the same machine, e.g. --kt-threadpool-count 1 --kt-numa-nodes 1
to bind to NUMA node 1. Previously this required external numactl
workarounds since subpool_numa_map was hardcoded to start from 0.
* initial fix for issue 1858
* [fix]: add done flag check to sync() wait predicate to prevent deadlock during destruction

* Increase timeout for Check if --kt-gpu-prefill-token-threshold is in the help output to 90 seconds.
In cloud environments,CUDA initialization and Python module loading can easily exceed 30 seconds.
* Update kt-kernel/python/cli/utils/sglang_checker.py

* [feat]: simplify sglang installation with submodule, auto-sync CI, and version alignment
- Add kvcache-ai/sglang as git submodule at third_party/sglang (branch = main)
- Add top-level install.sh for one-click source installation (sglang + kt-kernel)
- Add sglang-kt as hard dependency in kt-kernel/pyproject.toml
- Add CI workflow to auto-sync sglang submodule daily and create PR
- Add CI workflow to build and publish sglang-kt to PyPI
- Integrate sglang-kt build into release-pypi.yml (version.py bump publishes both packages)
- Align sglang-kt version with ktransformers via SGLANG_KT_VERSION env var injection
- Update Dockerfile to use submodule and inject aligned version
- Update all 13 doc files, CLI hints, and i18n strings to reference new install methods

* [build]: bump version to 0.5.2
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* [build]: rename PyPI package from kt-kernel to ktransformers
Users can now `pip install ktransformers` to get everything
(sglang-kt is auto-installed as a dependency).

* Revert "[build]: rename PyPI package from kt-kernel to ktransformers"
This reverts commit e0cbbf6364.
* [build]: add ktransformers meta-package for PyPI
`pip install ktransformers` now works as a single install command.
It pulls kt-kernel (which in turn pulls sglang-kt).

* [fix]: show sglang-kt package version in kt version command
- Prioritize sglang-kt package version (aligned with ktransformers)
over sglang internal __version__
- Update display name from "sglang" to "sglang-kt"

* [fix]: improve sglang-kt detection in kt doctor and kt version
Recognize sglang-kt package name as proof of kvcache-ai fork installation.
Previously both commands fell through to "PyPI (not recommended)" for
non-editable local source installs. Now version.py reuses the centralized
check_sglang_installation() logic.

* Handle unquoted paths and special characters in model scanner
* Fix ValueError: capture_output cannot be used with stderr
`capture_output=True` internally sets `stderr=PIPE`, which conflicts
with `stderr=subprocess.DEVNULL`. Replace `capture_output=True` with
explicit `stdout=subprocess.PIPE` to keep stderr suppressed correctly.
Also remove redundant `shell=False` (already the default).
