Version 37 (2 July 2020)

• The NAM has switched over to a new Java-based installer designed by daeley, with cross-platform support for any operating system that supports the Java Runtime Environment (JRE).
• The RealHighway (RHW) system has undergone a massive code overhaul ("Mark IV"), greatly improving stability, especially in compact situations. Diagonal x Diagonal (DxD) crossings (grade-separated) between wider RHW networks should now be possible in most situations.
• The RealRailway (RRW) system is now the default (and only) option for the Rail network. Users wishing to retain the original Maxis Rail should download the separate Maxis Rail Legacy Plugin.
• Various cosmetic/legacy plugins, such as the Bullet Train Mod (BTM) and El-Rail Alternate Implementation, are no longer directly available within the main NAM download, due to crosslink and support issues. They will be available as separate downloads, as Legacy Plugins with no guarantee of support or further upgrades.
• An initial basic version of the RealExpressway (REW) mod is now available.
• A pathing issue affecting intersections with the Diagonal Streets Plugin, dating back to NAM 20 (!) has now been fixed (thanks to McDuell).
• RRW Fractional Angle and FlexTrack switch content can now be constructed using easier-to-use FLEX Pieces, rather than memorizing drag/draw patterns. Some limited Fractional Angle elevated support is now available.
• The Road-based Single-Tile and Dual-Tile Network Widening Mod (NWM) networks now support Multi-Radius Curves (MRCs). For the single-tile networks, override the base Road MRCs with the appropriate NWM network to convert them, and use the dedicated pieces for the dual-tile versions (the RD-6 uses an override of the TLA-5 version--place Road stubs to fill in the "bites" on the RD-6 R4 curve).
• L3 and L4 FLEXFly pieces are now available for the RHW.
• RHW FlexSPUI has been redesigned, with improved support for the current array of RHW networks. Support for L0 and L2 is present (use the legacy TuLEP OnSlope to connect to the L2 version).
• Orthogonal TLA-3 and AVE-2 connections to the One-Way Road Roundabouts are now supported.
• Three new RHW FLEXRamps are now supported: Type D1-Inside (RHW-4 base), Type E1-Inside (RHW-4 base), and Type D1-Inside Dual Shift (RHW-6C base). Additionally, L1 and L2 support has been added to the Type A2 ramps for the RHW-8C and RHW-10S networks, and the L1 and L2 versions of the RHW-3 network now support Type A1 and B1 ramps.
• Various "tidal flow"-related pathing issues with the Draggable Elevated One-Way Road Viaducts have been addressed.
• File encoding issues with certain NAM files that have been known to cause crash-to-desktop (CTD) errors with Aspyr's new 64-bit macOS port of SimCity 4 (currently just the App Store version) have been fixed.
• A new bridge has been added for the NWM's NRD-4 network.

Changes introduced since the NAM 37 Release Candidate of 23/24 April 2020:

• The new FlexSPUI V2 now works properly in LHD mode.
• Drag pattern interference between the new draggable Road Small 90° Curve and the Road Long FA3 (71.6°) curve has been eliminated.
• Issues with various RHW and NWM bridges have been addressed, including the RHW-4 Small Steel Arch, the RHW-6S Concrete Arch Dual, and the NRD-4 Thru Truss. The accidentally-omitted DDRHW-4 bridge has also (again) be re-added.
• Missing textures/paths on some RHW T-intersections involving diagonals have been addressed.
• New draggable Road curves (Small 90° and Small S) have received Euro texture support.
• Issues involving the L1 RHW-8C crossings over Avenue have been addressed.
• Pathing for the RHW-3-to-ARD-3 transition has been fixed.
• The texture for the OWR-3 x OWR-2 +-intersection has been rotated to the correct direction.
• Tidal flow issues with the Slip Lane functionality, causing paths to not function in certain directions (esp. in LHD) have been fixed.
• Various Euro texture issues with the RHW-8C Type D1 ramp have been fixed.
• The OWR-1-to-MIS transition has been fixed.
• Avenue-to-MIS transitions have been fixed.
• Both US and EU textures for the RHW-6C and 8C Type D1 Dual Shift Inside FLEXRamp have been fixed.
• Various fixes have been made to the RealRailway (RRW) network.
• Pathing fixes have been made to the draggable Wide-Radius Curve (WRC)/Multi-Radius Curve (MRC) and Fractional Angle (FA) functionality.
• TLA Center Turn Arrow cosmetic mod now installed as option under Texture and Drive Side options, fixing previous file architecture issues.
• Mac-only issues with GHSR network showing Monorail supports have been fixed.
• Some INRUL-based issues with the RRW FlexTrack system have been addressed, particularly with the J2 Turnout (Ortho-to-FARR-1.33/1.5). Note that these changes have altered the availability of some drag patterns, and clicking on some existing switches may break them. Such switches will need to be rebuilt using their FLEX Piece equivalent.
• Note that no new features have been added since the NAM 37 Release Candidate. Addition of new content will resume with NAM 38 development.

Version 36 (13 September 2017)

• New FLEX Turn Lanes (FTL) feature added, providing a more intuitive and flexible alternative to the old Turn Lane Extension Pieces (TuLEPs, now deprecated).
• Draggable Elevated RealRailway (RRW) viaducts added at L1 (7.5 meter) and L2 (15 meter) heights.
• One-Way Road Signalized Intersection and Turn Arrow Project (SITAP) expanded to cover intersections with FLEX Turn Lanes and Road-based multi-tile NWM networks.
• Street Addon Mod (SAM) Set 11 - IndustrieSAM by mgb204 added, providing a new, industrial-style Street texture.
• Draggable Wide-Radius Curve functionality added to all applicable Street Addon Mod (SAM) override networks.
• RealRailway (RRW) FlexTrack functionality expanded to cover additional setups.
• R5 radius Multi-Radius Curves (MRCs) added to the Road network.
• Diagonal FLEX On-Slope Transitions added to the RHW, supporting 1 and 2-level transitions for the RHW-2, RHW-4, and MIS networks.
• R4 and R5 radii Multi-Radius Curves (MRCs) added to the RealHighway (RHW) system, with support for the L0 RHW-2, L0 RHW-4, and L0 RHW-6S netwoks. Overlap ability also added to the ground-level R2 curves for the RHW, allowing for smoother loop ramps.
• Diagonal MIS Connection support added to the One-Way Road Roundabouts.
• Texture glitch fixed with the Euro version of the L1-L4 RHW-6S Type A2 FLEXRamps/DRIs.
• Minor pathing fix to improve zone access on the TLA-7 network in the Network Widening Mod (NWM).
• The compression scheme on the NAM Installer has been changed, making it such that the external 7-Zip SFX layer surrounding it is no longer needed.
• New edition of the NAM documentation started, marking a return to the HTML format used prior to the NAM 31.x releases of 2013. Please note that due to the incredible scope of the mod, and the amount of time to adequately document features, that some sections may remain in an incomplete state.

Version 35 (4 November 2016)

• New RealRailway (RRW) FlexTrack functionality, including draggable Fractional Angle Railroads (FARR) at three angles (FA-2, FA-3, and FA-1.33/1.5) and improved Single-Track Rail (STR) support.
• Vastly improved adjacency stability for ramp-style RealHighway (RHW) FLEX Height Transitions, including many adjacencies with FLEXRamps and Draggable Ramp Interfaces (DRIs).
• Several new draggable NWM transitions: NRD-4-to-ARD-3, NRD-4-to-Avenue, NRD-4-to-TLA-5, NRD-4-to-RD-4, Road-to-RD-4, TLA-3-to-Avenue, TLA-3-to-TLA-5, AVE-2-to-TLA-5, AVE-2-to-Avenue, TLA-7/AVE-6-to-Dual-OWR-3, OWR-4-to-RHW-8S, OWR-5-to-RHW-10S, and OWR-1-to-MIS. These transitions can either be built through the stub method, or (in case of different base networks), direct connection.
• At-grade intersection support for the Road, OWR, and Avenue Viaducts, plus other stability and cosmetic improvements.
• Multi-Radius Curve (MRC) functionality added to the L1 and L2 RHW-2.
• A number of path fixes involving elevated RHW networks.
• Support for at-grade RHW-4 x Avenue, RHW-3 x Avenue and MIS x Street intersections (OxO only), as well as improvements and additions to RHW-2 and MIS diagonal intersections with Maxis surface networks.
• Proper P57-era RHW support for Moonlinght's Alternate El-Rail and Bullet Train (Shinkansen) mods (OxO only).
• Various fixes to the Maxis Highway Override (MHO), including improved RealRailway (RRW) support, support for moonlinght's Alternate El-Rail and Bullet Train, and Level Bridges for both L0 and L2 MHO networks.
• Re-implementation of some multi-tile RHW and NWM starter pieces, to improve stability in preparation for future additions. Legacy code has been added to provide stability to older, unconverted starters.

Version 34 (25 December 2015)

• The Tram-in-Avenue (TiA), Tram-in-Road (TiR), Tram-on-Road (ToR), and Tram-on-Street (ToS) dual networks are now partially draggable. To activate the dual networks, click the Elevated Rail tool over Avenue for TiA, the Elevated Rail tool over Road for TiR, the Rail tool for ToR, and the Elevated Rail tool on Street for ToS.
• Elevated RealHighway (RHW) networks and draggable Elevated Road, One-Way Road, and Avenue Viaducts can now form overpasses over Tram-in-Avenue, Tram-in-Road, Tram-on-Road, and Tram-on-Street dual networks. Simply drag the crossing network up to the edge of the Tram Dual-Network to form a stub, and begin dragging from stub on the other side of the Tram Dual-Network to continue the network. Some support for networks besides RHWs and the Road Viaducts has also been added, using similar means.
• RealHighway crossings over Network Widening Mod networks are now vastly more stable.
• Multi-Radius Curves (MRCs) for the Road network have been added in draggable form, in four different radii (R1-R4).
• Signalized intersections for One-Way Roads are now possible in the initial phase of the OWR Signalization and Turn Arrow Project (SITAP), complete with turn arrows before the intersection (NOTE: LHD functionality for this feature may still be limited). These signals cannot automatically appear, due to the game's handling of One-Way Road mechanics, but can be activated by transitioning from One-Way Road to Road just before the intersection. For intersections between two One-Way Roads, it is necessary to click over the resultant 90-degree Road bend with the One-Way Road tool. +-intersections and T-intersections between One-Way Roads and Roads, One-Way Roads, Avenues, and +-intersections (no T-intersections) with single-tile Road-based NWM networks (TLA-3, AVE-2, ARD-3, NRD-4) are available.
• 7 new bridges by eggman121 have been added, including the first-ever NWM bridges for the RD-4 and RD-6 networks, plus a new RHW-4 bridge, and four RealRailway (RRW) bridges.
• FLEX On-Slope Transitions for the Elevated Road, One-Way Road, and Avenue Viaducts have been improved to support tighter situations, where a network is directly below the elevated end of the transition.
• Many Elevated RHW base network features now show preview textures.
• An issue with High Speed Rail crossings over wider ground-level RHW networks has been addressed.
• An issue preventing the proper override of the ramp interfaces on L1 RHW QuickChanges has been fixed. Some clickaround may still be necessary to force the overrides to continue.

Version 33 (26 November 2015)

• Massive update to the Draggable Ramp Interface (DRI) and FLEXRamp systems in the RealHighway (RHW) Mod. 90% of all previous static puzzle piece ramps have been given easier-to-use FLEX and/or draggable counterparts, and a plethora of new ramp interfaces for elevated RHW networks are now available, Wealth textures are included for ground level versions.
• The RHW FLEXFly system has been completely overhauled, and now includes 90-degree and 45-degree versions, in single and dual-lane configurations, at Ground Level (L0), 7.5m (L1), and 15m (L2) heights.
• The double-decker RHW-4 (DDRHW-4) has been lowered one level (from L2/L3 to L1/L2), increasing ease of use. The DDRHW-4 has also gained support for DRIs and FLEXRamps, including A1 and B1 Outside and Inside Ramps.
• Disconnector added, to simplify demolition of FLEX-based RHW pieces.
• Multi-Radius Curves (MRCs), in both draggable and FLEX form, have been added to the RealHighway Mod, in three different radii, for the RHW-2, MIS, RHW-4, and RHW-6S.
• Stability improvements to the FLEX Height Transitions.
• Major improvements to the RealRailway (RRW) plugin, which now supports most crossings.
• Transit station functionality and compatibility has been further improved.
• Minor fixes to other NAM components.
• New High Speed Rail Project (HSRP) textures, courtesy of vershner.

Changes introduced since the NAM 33 Pre-Release of 29 July 2015:

• The RealRailway (RRW) FlexTrack system makes an earlier-than-expected debut. See the FlexTrack User's Guide in the Documentation folder for more details.
• PedMall functionality greatly enhanced with the addition of access paths to most non-Highway-type road networks, including NWM networks and Tram/El-Rail Dual-Networking items. Pedestrians may now directly access the PedMalls from these other networks without the need of a station or other transit-enabled lot/switch.
• Many custom bridges that previously blocked all ferry traffic have now been corrected.
• MandelSoft's previous RHW texture sets, including Euro, Ontario, and Irish/South African textures, have been discontinued. A new standard Euro RHW set, based on the default US set, has been added as a replacement, and adds compatibility for all current RHW features.
• An issue with the NAM 33 Pre-Release in which the Controller Compiler would fail due to an XML read error has been fixed.
• Several overhanging texture issues with the new RHW ramp interfaces have been corrected.
• The R3 FLEX-Multi Radius Curve now rotates fully as intended.
• A number of Left-Hand Drive transit path file issues across the entire mod have been added or corrected for proper functionality.

Version 32.1 [Mac-only] (28 June 2014)

• Solved file encoding issues on Additional Bridges, High Monorail, and High Elevated Rail, which prevented the NAM from running on Universal Binary versions of the Aspyr Mac port of SimCity 4 Deluxe.
• Introduced an installer to NAM Mac version, using a Wineskin wrapper of the Windows installer.
• Addressed some other transportation-related issues present in the Aspyr Mac port.

Version 32 (14 January 2014)

• The NAM Elevated Viaducts for Roads, One-Way Roads, and Avenues are now available in a draggable form, at both Level 1 (7.5 meter) and Level 2 (15 meter) heights, complete with FLEX Height and On-Slope transitions. Overpass situations involving one or more diagonal networks are not yet supported.
• Elevated Rail-over-Avenue and Elevated Rail-over-NWM Road-4 dual-networking support has been added, complete with a new station supporting both networks.
• The initial phases of the RealRailway (RRW) system have been added. This feature must be selected as part of a custom install.
• The RealHighway (RHW) system has been expanded to include the QuickChange interchange system, which blends the RHW's modularity with the ease of Maxis Highway construction techniques for certain situations, which will be expanded in future NAM releases. Additionally, several new types of FLEXRamps are available--please read the instructions in the description text. FLEX Transitions have also been given stability improvements for certain situations.
• Coupled with the RHW system, the NAM now offers Bus Rapid Transit (BRT) functionality, including stations.
• Transit station functionality has been further improved, including the beginning of the implementation of the SLURP, which will gradually raise all transit stations to NAM standards.
• The NAM Controller Compiler has been included with the installer, with which it now communicates, ensuring that only the installed features are incorporated into the NAM Controller, reducing file size and load times. (The e-series and s-series controllers have been discontinued.)
• About 50 bugs reported since the start of the NAM 32 Pre-Release have also been squished, including some that had been present since earlier versions of the NAM. It is highly recommended that users update to the latest NAM in order to enjoy a more stable experience.

Version 31.2 (4 June 2013)

• Integration of 4GB Patch into installer, further preventing risk of CTDs on newer systems.
• Maxis Highway Custom Interchanges button re-enabled, after fixing HID re-index issue in RUL0 file.
• "Sinkhole-to-China" bugs fixed on several RealHighway (RHW) pieces.
• L2 RHW x RHW OxD Stability improved.
• Maxis Highway Override/"Project Symphony" Type A ramp is now able to be fully rotated.
• RHW-10S bridge no longer has issues with missing tiles.
• DDRHW-4 paths now at proper heights.
• Maxis Highway Override/"Project Symphony" no longer causes CTDs when dragged under High Speed Rail.
• Further improvements to RealHighway filler pieces.
• Maxis Highway Override/"Project Symphony" OxD crossing with Rail Viaducts now facing the correct direction on all tiles.
• Multiple "rainbow tile" issues fixed.
• Some files moved from Rail Viaducts to Base Contents, to address issue with "missing tiles"
reported by users who did not install the viaducts.
• Several LHD path fixes for bridges.
• Under/overpass on starter situations improved for RHW starters.
• While the expanded RealHighway functionality available in the 31.x-series releases is much more stable in Version 31.2, issues still exist with the L1 and L2 Diagonal RHW-6C, 8C, 8S, and 10S, when crossing over other RealHighways. The overpass may behave as if it is prevented, or produce inexplicable results. Due to the complexity of the coding for any sort of crosslinking between two override networks (especially when one is multi-tile and diagonal), solving this issue is a veritable "needle in the haystack" situation, and will take substantial time to correct. *Support will not be provided for issues involving these overpasses.*
• Two multi-purpose transit stations by E-N of BriPizza have been added, serving the orthogonal intersections of almost all single-width networks that differ in height by 15m.
• The NAM Ideal Transit Switches (NITS) have been introduced. The NITS provide greatly increased efficiency for all combo NAM transit stations (e.g., all stations with subway access and at least one other major network), which results in greater network usage.
• Controller updated to version r184.
• Please note that the installer will "seek and destroy" old NAM installations in your Plugins, so there is no need to worry about uninstalling/deleting your old NAM.

Version 31.1 (6 April 2013)

• Controller divided into two different packages to improve stability--the smaller "standard" (or "s-series") package, and the larger "extreme" (or "e-series"), to improve stability issues present with NAM 31.
• Road Turning Lanes "semi-automatic" functionality has changed implementation, from Rail overclick to One-Way Road overclick.
• A number of transit stations have had bugs fixed or performance otherwise enhanced, and several optional new stations have been added. For PC users, any stations plopped in your cities from NAM 31 will automatically be upgraded when you install NAM 31.1.For Mac users, the replacement set of basic Maxis stations had to be modified, along with the Modern El Train Station by Brenda Xne. These fixes were necessary due to a bug in the Mac version of SC4. If you're a Mac user and you plopped any of these stations from the NAM using version 31, you will have to bulldoze them and replop them once you have installed NAM 31.1.
• New Street network functionality: Some new draggable wide-radius curves, and intersections along wide-radius curves, are now possible with the Street network.
Credit for this new feature goes to Swordmaster from the NAM Team.
• RealHighway Filler Pieces have been restored and expanded after previous issues.
• Installing over previous versions: NAM 31.1 may be installed directly over top of any previous NAM releases. It is a full release, not a patch or a hotfix. All future updates are planned to be in full package form, and there are no plans to issue patches or hotfixes in the future. Please also note that the NAM Team only provides technical support for the most recent version, which, as of this document, is NAM 31.1. We cannot assist users of the original NAM 31 release, or NAM 30 (or earlier).
• Special Thanks: The NAM Team would like to thank the following members of the community, who have tested the penultimate build of the NAM 31.1 controller and given their feedback on its stability, and/or assisted with other controller-related tests after the NAM 31 release, in an effort to nail down the game stability issues: A Nonny Moose, dyoungyn, Joe 90, mgarcia, mneonnew, shanghai kid, spot, and txrailcat74.

Version 31.0 (2 March 2013)

• The NAM has changed to a "monolithic" package. With the exception of the Diagonal Bridge Enabler (DBE), all other separate-download NAM plugins have been merged into the main package, including the RealHighway Mod (RHW), the Railway Addon Mod (RAM), the Network Widening Mod (NWM), the High Speed Rail Project (HSRP), the Street Addon Mod (SAM), and the Rural Roads Plugin (RuRP). All NAM-issued bridges have also been incorporated into the package. These plugins may all be selected as options in the new and improved NAM installer.
• Substantial expansion of the RealHighway (RHW) Mod network options, including the addition of the full Multi-Height System, which allows four elevated heights-L1 (7.5m), L2 (15m), L3 (22.5m), and L4 (30m). All widths of the RHW also now have L1 and L2 elevated counterparts, and the RHW-4, RHW-6S, and MIS Ramps have L3 and L4 available.
• The RHW also now includes FLEX Height Transitions (FLEX-HT), FLEX On-Slope Transitions (FLEX-OST), FLEX Ramp Interfaces (FLEXRamps), accommodating many of the new networks without adding massive numbers of new puzzle pieces.
• Draggable Fractional Angle Roads have been added at two different angles-FA3 (18.4°/71.6°) and a new angle, FA2 (26.6°/63.4°).
• For the first time ever, the NAM now includes Lots, adding a basic variety of stations for NAM override networks that require them, including Ground Light Rail, the Tram/El-Rail Dual Networks, and High Speed Rail.
• Starter Pieces have now been converted to include a self-destructing construction lot, simplifying construction.
• Hole Diggers and Raisers have also been added in two forms: the conventional Lot-based approach, and a new self-destructing variant.
• Maxis Highway Override, AKA Project Symphony, has been added. This plugin converts the Maxis Highways from 6 undersized lanes, to 4 RHW-scaled lanes, and better allows the network to interface with RHW functionality.
• Wide Radius Curves added to the Monorail network.
• Moonlinght's popular Alternate El-Rail Mod and Bullet Train (Shinkansen) Mod have been added as optional skins for the El-Rail and Monorail networks, respectively.
• Two new SAM sets have been added: the Klinker Streets by squidi, and moonlinght's Japanese Streets.

(Please note that due to the model-based nature of this functionality, the natively-built pillars on the Elevated Rail network had to be removed. You may need to reconstruct sections of your Elevated Rail network to re-add the pillars with this plugin installed.)
• RUL updates for the RealHighway Mod (RHW), Network Widening Mod (NWM), Street Addon Mod (SAM) and Diagonal Bridge Enabler (DBE), all downloaded separately.

• Left Hand Version Rail-Networks Fix: A fix has been made, for players who actively use Left Hand Version of the game, for all of the Rail-Based networks. This fix encompasses Rail, ElevatedRail, MonoRail, & Subway networks & any intersections involving these networks. This fix makes adjustments so that the Trains on these networks operate & run on their proper side for Left-Hand Version players, just like cars do on road based networks. This fix is also UDI compliant (where applicable). This fix is only applicable & only intended for active Left-Hand Version players. This fix subsequently has a bearing on Transit Enabled Lots. Left-Hand Version players please see the Installation Instructions for additional Plugin(s) required. For more details regarding this fix please read the Technical Notes.
• Numerous visual improvements made to various existing items ~ of which there is to many to list.
• OneWayRoad Bridges have been adjusted. The models & textures they use are no longer dependent on the games own files, & hence can be changed. Please see the Contents for more details.
• Monorail over Elevated Highway overpass.
• Double Diagonal Rail x Orthogonal Avenue (this is a normal ground intersection).
• Numerous new Puzzle Pieces added. Any new Puzzle Pieces have been placed in their appropriate menu button. A majority of new Puzzle Piece items have been integrated into their existing appropriate Puzzle Pieces menu position & can be accessed via the Home/End keyboard key. For example; the Diagonal Road Start/End Puzzle Piece is integrated along with the existing Orthogonal Road Start/End Puzzle Piece. Using the Home/End keyboard keys will rotate the item from orthogonal to diagonal to orthogonal etc. The same applies to many other Puzzle Pieces containing a Diagonal component. Please see the Contents for more details.
• OneWayRoad Puzzle Pieces have been overhauled to address Pathing/Automata issues that currently exist with them. Most OneWayRoad Puzzle Pieces now contain Directional Enforcing & contain Directional Arrows to assist with their placement & general use. Please note: For this reason any existing OneWayRoad Puzzle Pieces should be checked, preferably bulldozed & replaced, especially if Pathing issues start to arise. The game should also be given some time to adjust & update because of this. This adjustment will ultimately reduce the Pathing/Automata issues that currently exist with this item & make them function more efficiently. Using either query tools &/or the bulldozing tool & highlighting OneWayRoad Puzzle Pieces (one tile at a time only) will show these Directional Arrows, & hence the flow of direction.
• The above paragraph subsequently also applies to OneWayRoad Overpasses.
• The existing 1x1 Avenue Filler Puzzle Piece has been overhauled to address pathing/automata issue that currently exist with the item & now contain Directional Enforcing. Please note: For this reason any existing 1x1 Avenue Filler Puzzle Pieces should be checked, preferably bulldozed & replaced, especially if Pathing issues start to arise. The game should also be given some time to adjust & update because of this. This adjustment will ultimately reduce the Pathing/Automata issues that currently exist with this item. Directional Arrows have now also been added to applicable 1x1 Avenue Filler Puzzle Pieces & preview models to assist with their placement & general use. Using either query tools &/or the bulldozing tool & highlighting applicable 1x1 Avenue Filler Puzzle Pieces (one tile at a time only) will show these Directional Arrows, & hence the flow of direction.
• Various other file item adjustments, improvements &/or fixes ~ of which there is to many to list.
• Main NAM.dat surpasses 8,000 files.
