 # Changelog
 
+## 1.9.8 - 2026-10-09
+
+- Reorganize the bilingual project landing page into feature sections with grouped screenshots, blue controls and larger text. Retain the video demonstration, crop its white borders and add full-viewport image/video previews with a top-right close button.
+- Publish updated English and Russian CIMCO Edit 8 comparisons in `COMPARISON.md` and `COMPARISON_RU.md`, with collapsible tables on both landing pages. Clarify Russian technical descriptions and restore Statistics navigation.
+- Add the project website above the author in About and a localized Close button to the STL Objects panel.
+- Limit exported HTML statistics tables and SVG projections to 900 px; scale projections to the available window height. Show the coordinate origin and positive XY/XZ axes, preserving the marker when filtering by tool. Refresh the downloadable example report.
+- Register both Fusion benchmark fixtures in the corpus and verify the two G41 corner joins in the full native CAM GUI regression. Simplify milling preset and cycle validation to satisfy lint checks without suppressions.
+- Execute the complete paired Fusion 1001 benchmarks through M30 on AC table kinematics. Add native CYCLE85/86/87/89, deep/left CYCLE84, FANUC G74/G76/G87/G89 and synchronized G74/G84 Q pecks. Preserve feeds, clearance shifts and spindle/stop signals.
+- Resolve Siemens circle planes from endpoint addresses without changing the modal plane. Allow pure native rapid indexing under CYCLE800; normalize signed/unwrapped Fusion DC targets for backplotting with source warnings.
+- Handle G92.1 as a non-motion coordinate preset and restore all explicit absolute axes after unsupported blocks.
+- Reject inconsistent milling IJK radii and zero-sweep arcs with source-line diagnostics, preserving full circles and configured arc tolerances.
+- Transform absolute IJK centers consistently with G52, WCS, rotation and scaling. Preserve native SINUMERIK AC centers without applying offsets twice.
+- Correct G18 cutter-compensation projection and arc direction, and include the starting point in turning profile-arc membership checks.
+- Align default motion budgets, arc tolerances and IJK autodetection across GUI, CLI analysis and export. Keep explicit execution limits and manual arc selection available.
+- Expose program wrappers, comment style, decimal precision, forced decimal and positive-sign options in single and batch CLI export. Use the source controller for direct API Auto export and detect each batch input's machine type when --lang is omitted.
+- Allow DXF export of available partial execution geometry while retaining diagnostics and blocking incomplete NC output.
+- Clarify that G76 marks the lead-based axial chamfer interval but does not model an angled radial pull-out.
+- Accept repeated native SINUMERIK rotary targets under CYCLE800 without changing geometry. Identify CYCLE800 in native rotary-frame diagnostics and describe the simulator limitation.
+

 ### How is G76 chamfer modeled?
 
-The packed chamfer digits are converted into an axial chamfer length based on thread lead. The final part of each thread pass is split when necessary to represent the chamfer section.
+The packed chamfer digits mark an axial interval based on thread lead. The current model splits the final part of the pass into collinear segments; it does not simulate an angled radial pull-out or the resulting physical chamfer. The controller's pull-out angle is not configured, and the tool angle in P is not a substitute for it. No universal 45-degree exit is assumed.

+If every candidate is ambiguous, the selected fallback mode is used. GUI, CLI parse/trace/analysis and file/batch export enable detection by default for both milling and turning; CLI uses relative IJK as the fallback. Shared application execution uses the GUI's default 0.01 mm arc tolerance. Direct kernel calls retain explicit mode/tolerance controls and a 0.001 mm default for turning.
 
 Selecting an Arc Type in the GUI manually overrides auto detection for the current document. The Auto Detect setting remains enabled for the next opened document. In turning, an I/K arc interpreted with the wrong center mode reports `INVALID_TURNING_ARC_CENTER`; selecting Radius mode for an arc without an R word reports `TURNING_ARC_REQUIRES_R`.

-The corpus also includes [ext_cycles.mpf](tests/fixtures/milling/sinumerik/ext_cycles.mpf) and [no_ext_cycles.mpf](tests/fixtures/milling/sinumerik/no_ext_cycles.mpf), retained as posted. They are mixed supported/unsupported audit programs, not examples of complete successful execution. Common CYCLE81/82/83 operations have matching geometry in their respective profiles. The extended file first stops at line 216 on deep/chip-breaking CYCLE84; the classic file first stops at line 200 because its CYCLE84 declaration has 21 positional parameters, beyond the current classic limit of 18. Left-hand/deep tapping and CYCLE85/86/87/89 are not modeled. Native M19 is supported as a spindle-orientation signal. Selecting the extended interface does not enable those operations.
+The unchanged [ext_cycles.mpf](tests/fixtures/milling/sinumerik/ext_cycles.mpf) and [no_ext_cycles.mpf](tests/fixtures/milling/sinumerik/no_ext_cycles.mpf) now execute completely in their selected profiles, including deep/left tapping and CYCLE85/86/87/89. Native M19 emits a spindle-orientation signal.
 
 Arc-center interpretation follows the executed controller mode: native and ISO-M (`G291`) use incremental IJK centers; native I=AC/J=AC/K=AC explicitly selects absolute centers. Mixed `G290/G291` input resolves each arc in its active mode; document arc settings and automatic detection do not override these semantics. Configured native rotary axes are supported by the bounded TCP/indexing subset; rotary A/B/C in G291 remains rejected.

 Cython accelerates contiguous literal position runs, with per-block capability validation before state changes. Controller-specific declarations and G290/G291 switches interrupt the current run, after which eligible positions resume acceleration. Positions inside an active MCALL cycle stay on the Python reference path until cancellation. Metadata or a native cycle elsewhere in the file does not disable acceleration for the whole program.
