legacy 1.4 update

IMO, the 1.51 update is the one to get.   There are release notes on the Lionel site, not sure what all was done.  Here's what the manual says for 1.4.

 

V1.4 Feature Summary
The V1.4 release improves usability, stability and adds some new features based on
feedback from users and requirements to support future products. Below is a list of the
major enhancements and differences from V1.2 and V1.3.
Faster Boot Up
• The remote splash screen has been removed to speed up the time it takes
to power up a remote. In addition, the remote remembers the last addressed
device when booting up.
Improved Auto-brake
• Velocity throttle controlled autobrake has been improved. The new behavior
of auto-brake allows you to control the brake sounds intensity, much like the
legacy brake rocker. The more you turn the knob below zero the brake sounds
increase.
Base Serial Improvements
• The base now has the ability to be accessed via serial port. This allows LIONEL
computer applications to read and write the internal memory and/or memory
module. LIONEL computer applications are not available as of this writing.
Improved Radio Driver
• The communication link between the base and remote has been improved in
both distance and reliability.
Manual RPM control
• Manual RPM control has been added that creates control similar to TMCC
manual RPM mode. See page 20 for more details on how to use this feature.
Improved RPM control in TMCC engines.
• Train brake no longer causes TMCC engines to ramp down the RPM, and using
high momentum with TMCC engines no longer causes the RPM to change over
time. RPM's will only change when you turn the knob.
Routes
• All routes are now double digit. This gives you time to view the route name
before ring the route. It also allows them to be con gured in the same manor
as all other devices (Scroll, addressing history, info, name). See page 69 for more
information on this feature.
Engine Queue
• The CAB now has an ‘engine queue’. This system allows changes to continue
in the background. When you have an engine or train that has not reached its
target speed and you ‘deselect it’ (change to another engine or leave the main
operating screen) the queue will take over controlling that engine. Currently the
queue will run up to 5 engines in the background. See page 58 for more details
on this feature.
Labor (EFX) Bias Control
• More labor can now be applied without affecting the speed of the train. Two
new touchpad keys have been added on the speed page to control this feature.
See page 30 for more details.

 

Specific Engine Types
• Additional device types have been added to the ENGINE INFO page to support
the new TRAIN LINK function. See page 57 for more details.
Engine Info Page Improvement
• The ENGINE INFO screen has been streamlined to make it simpler to use. In
addition, Memory Modules can now just be inserted to be recognized. See page
46 for more details.
Train Builder Improvements
• SOUND MASKING has been implemented giving the ability to move the dialog
and horn output on the newest LEGACY engines and some TMCC/LEGACY
combinations such as Super Roar. See page 61 for details.
• TRAIN LINK has been implemented to give quick access to operating cars
within a train. TRAIN LINK devices are indicated with a LINK over the engine
icon. See page 28 for more details.
• Each train device has a graphic representation in the consist. For example, if
you add a crane, you see a crane icon. See page 64 for more details.
• HYBRID MODE support has been implemented for the Super Bass Roar Unit
(TMCC engine as head, Super Bass Roar Unit in LEGACY mode in rear) This
will output labor commands in TMCC mode to trigger the Super Bass Roar Unit.
See page 62 for more details.
• Support for LEGACY Switchers has been implemented. If a switcher is lashed
up with other LEGACY engines, they will all run at the same speed and allow
LEGACY switchers and road engines to run in a lashup. See page 62 for more
details.
• AUTOMATIC SPEEDLIMIT has been implemented to resolve lashing problems
with engines having different top speeds. See page 62 for more details.
• Accessories can be placed in a consist and accessed with TRAIN LINK. See
page 65 for more details.
• The name of engine will be displayed in the Train Builder. See page 61 for more
details.
• The select and scroll keys can now be used in Train Builder to add engines with
ease. See page 64 and page 65 for more details.
• ENGINES CAN NOW EXIST IN MULTIPLE TRAINS making it easier to manage.
See page 62 for more details.
Additional Icons
• Several new icons were implemented into the LEGACY software for Legacy
passenger and Acela cars for lighting scenes and Speed Control for the Acela
Power management for extended battery life
• Cab-2 Remote Controller will turn off sooner, preserving batteries;

Thanks John,i have seen forum members say they are going from 1.3 right to 1.5 & i was wondering why they skipped 1.4,i do plan on going to 1.5 soon.

Actually those are 1.3 added features. 1.4 was only ZW-L support and REL100. The 1.4 manual was a cut and paste from 1.3

I knew some of that was from 1.3 and earlier, just didn't remember what.  The R100 support didn't work properly for the CCM in 1.4 anyway...
