 # Changelog
 
+## 1.9.6 - 2026-10-08
+
+- Add the supplied NX `text_NX.mpf` to the fixture corpus. Verify all 571 motions, completion at M30, and unchanged geometry when its five unmodeled auxiliary M codes are removed.
+- Make Editor G0, G1 and G2/G3 lexer colors configurable in Options / Colors, preserving custom values across theme/file-type changes and supporting Cancel and Restore Defaults.
+- Distinguish orange warning rows from red error rows in Tokens/Macro Variables. Open the full source block and diagnostic text on double-click without requiring copy/paste.
+- Split the bilingual landing page into editable HTML fragments with a deterministic assembler and stale-output check. Link README to the published English/Russian site. Synchronize FAQ/site controller tables for inverse-time feed, programmable frames, reference returns and non-blocking M codes; clarify post-template cycle reconstruction.
+- Keep unmodeled auxiliary M codes as non-blocking warnings in FANUC milling/turning and SINUMERIK native/ISO execution, including blocks containing motion or known M codes. Preserve M2/M30/M99 flow semantics and prevent ignored SINUMERIK M98 from invoking FANUC subprogram dispatch. Add trajectory and controller-flow regressions.
+- Execute native SINUMERIK programmable TRANS/ATRANS and ROT/AROT as rigid frames, replacing or composing in local axes and preserving physical tool position without emitting motion. Support XYZ spatial rotations with the documented default RPY order and RPL in G17/G18/G19; retain WCS and fail closed on unsupported composition. Preserve transformed analytical arcs/helices, FULL frame syntax and tolerance-controlled EXPANDED output. Remove unmodeled frame warnings and add independent geometry, reset, parameter, WCS, export and real impeller regressions.
+- Resolve native SINUMERIK CIP spatial arcs through their intermediate point, including G90/G91 and explicit AC/IC point coordinates. Preserve analytical geometry for plot, playback, lengths and bounds; linearize spatial arcs within the configured tolerance for EXPANDED conversion. Verify the CIMCO parallel-arc example and add independent geometry and replay regressions.
+- Detect native SINUMERIK commands in unnamed pasted editor text without saving or adding a Toolbar selector. Ignore comments and quoted strings; follow Undo/Redo and apply native comment/arc defaults without changing persisted preferences.
+- Accept classic 14-argument native SINUMERIK CYCLE800 calls with omitted FR_I/DMODE. Resolve classic ST0/ST1 new/additive frames through the existing swivel model; retain kinematics and composition checks. Add regressions for the CIMCO normal-plane call and documented Siemens classic frames.
+
 ## 1.9.5 - 2026-10-08
 
 - Preserve CRLF in translation sources after PowerShell lupdate generation so the Windows workflow's subsequent lint check passes. Make Play/Pause artwork tests portable by checking public tool-button properties instead of calling a protected Qt method on a C++-created widget.

-Native CR radius arcs require a SINUMERIK source document: use .mpf/.spf. A .nc or unsaved document uses FANUC syntax and cannot interpret CR= as a native radius address. Native X/Y/Z=IC(...) is incremental independently of G90/G91. MSG() is accepted.
+Unsaved editor text selects native SINUMERIK when executable commands such as SUPA, CIP, MCALL, TRANS or CYCLE800 are present. Comments and quoted strings do not select a dialect; Undo/Redo updates the selection. Named files retain their extension-based source contract.
+
+Programmable `TRANS`/`ATRANS` and `ROT`/`AROT` affect subsequent XYZ geometry relative to the active WCS. `TRANS` and `ROT` replace all programmable frame components; bare `TRANS` or `ROT` resets the frame. `ATRANS` adds a translation in the current local axes; `AROT` adds a local rotation and preserves translation. Changing the frame rebases program coordinates without moving the physical tool. Spatial XYZ angles use the default Siemens RPY order Z → Y′ → X″ (MD10600=1), regardless of address order in the block. Machines configured for Euler order are outside this policy. `RPL=` rotates in the active plane about +Z (G17), +Y (G18) or +X (G19). Each command requires a separate NC block and accepts numeric values, direct R references or supported named scalars; general expressions are not added. Active TWP/CYCLE800, TCP, polar mode, cycles and cutter compensation cannot be combined with these commands. SCALE/ASCALE and MIRROR/AMIRROR remain unsupported. FULL preserves frame commands; EXPANDED resolves their effect into output coordinates and linearizes arcs whose physical plane cannot be represented by the selected standard plane.
+
+Native CR radius arcs require a SINUMERIK source document: use .mpf/.spf, or unnamed text detected by executable native commands. A named .nc document retains FANUC syntax. Native X/Y/Z=IC(...) is incremental independently of G90/G91. MSG() is accepted.
 
 `CYCLE84` accepts the 24-argument CAM call and shortened numeric declarations. Depth uses `DP` or positive relative `DPR` in compatibility mode; explicit absolute-depth `AMODE=2/1001002` requires `DP`. Deep tapping, `MPIT`/thread tables, nonmetric pitch units, spindle orientation/technology options, left-hand tapping and unequal entry/withdrawal speeds are outside this subset and produce diagnostics. Spindle synchronization/reversal is represented by logical signals, without angular spindle simulation. The parameters follow [Siemens section 1.7](https://m3.tuc.gr/EQUIPMENT/CTX310/840D%20G-CODE.pdf); paired fixtures `tapping_sin840d.mpf` / `tapping_fanuc.nc` verify G84 geometry and native trace replay.

 Native `TURN=n` adds integer 0..999 complete revolutions to the base `G2/G3` arc (IJK or CR, G40, no active MCALL), according to [Siemens](https://support.industry.siemens.com/cs/attachments/104985512/802Dsl_BPF_1006_en.pdf). The trace keeps one analytical arc/helix with the total sweep. Rendering, playback and statistics retain those turns; DXF uses a sampled polyline, and FANUC/ISO exporters split arcs only during serialization. The existing stock material-removal timeline supports turning; this release does not add milling stock removal. Standalone native `G4 F...` uses seconds and leaves modal feed unchanged; spindle-revolution dwell is not modeled.

Configured numeric A/B/C assignments and direct R references follow G90/G91; rotary TCP arcs retain analytical Cartesian geometry and orientation endpoints.
