- New nodes: Image Resize plus the Utility group (Text, Integer, Float, Show Text, Math Expression, Select Every Nth, Split Batch, Merge Batches, Free Memory) - the dependency-free gaps that let shared workflows drop heavy packs. - Replace with AusBoss nodes (prototype): preview-then-confirm graph rewrite swapping known third-party nodes for pack equivalents, with a tested translation map, per-node opt-out, and refuse-with-reason for nodes the pack cannot stand in for. - Load Video: single-frame FRAME picker, an honest "what will load" label from the probed source rate, drop-a-video-to-restore. Save Video: format-aware widgets and a file_path output. Stitch Inpaint gained a blend_mask output, Select Frame negative from-the-end indexing, Image Size a batch count - all appended, saved workflows load unchanged. - LoRA Loader: drag-to-reorder rows, hover thumbnails on rows, file size and date in the info card. - Appearance: flagship scheme deepened to slate-teal; the retired bright-teal pair upgrades automatically via LEGACY_SCHEME_PAIRS. Optional queue-completion chime, off by default. - Image Resize invariant: pixels are only invented on an explicit width+height pad request - scale-derived modes resolve divisible_by snaps with a sub-half-step resize, never bars. - Docs refreshed for six stale pages, stale text and metadata fixed across the pack, the panel-height rule codified in AGENTS.md and the brand skill, and ausboss_node_tour.json added - a model-free example exercising 17 node types in one graph. Validated: scripts/validate_nodes.py (24 files), 300 JS tests, all Python suites under the ComfyUI embedded interpreter.

# Math Expression
|
|
|
|
Evaluates one arithmetic expression over the inputs `a`, `b` and `c` and
|
|
returns the result as both `FLOAT` and `INT` — width and height math,
|
|
strength ramps, frame counts.
|
|
|
|
## Controls
|
|
|
|
- **expression**: The arithmetic to evaluate. Allowed: numbers, the names
|
|
`a`/`b`/`c`, the operators `+ - * / // % **`, parentheses, unary minus, and
|
|
the functions `min`, `max`, `abs`, `round`, `floor`, `ceil`, `sqrt`.
|
|
Examples: `a * 2`, `floor(a / 64) * 64`, `min(a, b) + 0.5`,
|
|
`sqrt(a*a + b*b)`.
|
|
- **a**, **b**, **c**: The values the expression reads. Type them or convert
|
|
them to inputs and wire numbers in; an unused one costs nothing and an
|
|
unwired one reads as its widget value.
|
|
|
|
## Outputs
|
|
|
|
- **float**: The result as a float.
|
|
- **int**: The result rounded to the nearest whole number; halves round away
|
|
from zero (`2.5` becomes `3`, `-2.5` becomes `-3`).
|
|
|
|
## Safety
|
|
|
|
The expression is parsed with Python's `ast` module and walked against a
|
|
whitelist — it is never passed to `eval`. Anything outside the grammar above
|
|
(other names, attribute access, subscripts, strings, comparisons) stops the
|
|
run with an error naming what to remove, so a workflow shared by someone else
|
|
cannot smuggle code through this node. Division by zero and overflowing
|
|
results are clear errors rather than a crash or an `inf` traveling
|
|
downstream.
