strip_prefix returns the detected prefix instead of logging it, so the load
summary reports it alongside the key count and the redundant reading-state
marker is gone. Four near-identical cls/file lines become one.
Base ships last.up all-zeros so the branch is a no-op; pre-branch
finetunes omit both keys. A zero_init_missing spec field zero-fills
them on load instead of falling back to the base transformer.
Under uv, install --upgrade re-resolves the full dependency set eagerly: the pinned tokenizers and transformers installs bumped typing-extensions past its requirements pin on every update, and the requirements check then downgraded it back, flagging a restart each time. The preceding uninstall and exact pins already force the intended change, so the flag only produced churn. The pip-routed diffusers install is aligned for consistency.
The post-upgrade restart depended on a pinned requirement drifting in the same run, since the requirements check was the only place that set restart_required. The direct check compared a short hash and date string against a full sha and never fired. Set restart_required when the repository update moves HEAD so an upgrade restarts even when no package pins changed; a no-op pull now logs the repository as unchanged instead of upgraded and skips the restart.
check_transformers and check_diffusers compared the target commit against a marker stored in server options, which is only persisted after full webui startup. An upgrade restart fires before that point, so the marker stayed stale and the next launch reinstalled the same pin again. Read the installed commit from the package dist-info direct_url.json instead; the options values remain as informational display.
strptime was handed the stat datetime instead of the date string, so it
always failed and left a raw string mtime; the Date sort then crashed on
mixed str/datetime items. Parse the date string, falling back to stat mtime.
CivitAI has no model type for a standalone transformer, so DiT finetunes
are published as 'Checkpoint' like full models and all landed in
Stable-diffusion, where the single-file transformer loader never looks.
Route Checkpoint downloads to UNET unless the base model is a known full
checkpoint (SD1.x/2.x, SDXL and its Pony/Illustrious/NoobAI derivatives,
SVD, Kolors, Stable Cascade). Downloads with no base_model, or a
civitai_save_type_folders override, keep the previous behavior.
An absolute 1024-byte floor rejected valid complete downloads, since
some safetensors are legitimately tiny (a lone projector-diff tensor is
~160 bytes). Verify completeness against the declared Content-Length
instead, accepting any size, and keep the floor only as a fallback when
it is missing. Reject text/* responses up front so an HTML error or
login page served with HTTP 200 is never saved as a model file.
The LTX tab already collected a last-frame image but anchored every condition at index 0, so it never acted as a last frame. Build a separate condition for it at the final frame: index -1 for the 2.x family (latent index, negatives wrap) and num_frames-1 for 0.9 (pixel index). The Last image input now shows only for Condition models, the pipelines that accept multi-frame conditioning.
The I2V path forwards a last-frame image to the pipeline when one is supplied and the loaded pipeline accepts it, turning the run into first-last-frame interpolation. supports_last_frame() gates on the pipeline taking a last_image argument and not running expand_timesteps, which conditions on the first frame only, so a model that cannot use a last frame logs a warning instead of silently ignoring it.
