[Edited Message Follows]

We just posted some changes to the components, here is the. changelog.  Several of these changes will require significant doc for you to use so more to come:
AB:

• Add AGC update including new settings

• In AB.ini you can now set usrpAgc to adjust the threshold, slope and decay of the AGC

• "Threshold" specifies AGC Knee in dB if AGC is active.( nominal range -160 to 0dB)

• "Slope" specifies dB reduction in output at knee from maximum output level(nominal range 0 to 10dB) 

• "Decay" is AGC decay value in milliseconds ( nominal range 20 to 5000 milliSeconds)

• Add reloadDatabase remote command
• This command (issued from dvswitch.sh) will cause AB to reload its internal database of users from disk.  This is normally done once every 24h

• Add menu command (does not popup menu on mobile)

• Like the "macro" menu for DVSM/pyUC, the menu command loads a transient menu into the client. 
• Unlike the "macro" command (which now popups up immediately) the menu command just loads the menu
• This command is most useful in conjunction with the OnRegister macro

• Support USRP ping back (NAT keep alive)

• Allow AB to respect a reverse keep alive from the mobile client for some NAT situations

• Multiport transmit to support better bridge creation

• This requires a full post all by itself, but the quick description is that a comma delimited list of transmit ports is now supported by AB and MB
• The main purpose of this is to support better bridge architectures
• Other uses include logging and streaming 

• Allow macro variables with substitution

• Again a single change that requires a full post.
• Variables are now supported in the macro section of AB.ini
• The variables are substituted by the shell before command. execution
• The variables allow for much more concise command line strings
• The variables make for much more readable macro definitions
• Less dedicated scripts will. be needed as the macro definition can be defined in the section alone
• Variables are exported to the environment and be used by client scripts for context

• Better ini parsing error messages

• When an error. is encountered in the parsing of the ini files, a better error message is. generated to. help diagnose the problem

• Add warning if call not found in database (DSTAR)

• DSTAR/ircddbGateway is picky and wants a valid callsign to operate.
• This warning tells you that a call can not be found in the database that matches the DMR ID/CCS7 provided in "gatewayDmrId"

• Add name lookup and metadata export

• Metadata exported from the USRP interface now includes the first name and callsign of the DMR ID
• The information comes from the database file loaded by "subscriberFile"

• Change default transferRoot to /tmp

• Change the default so that users who fail to set this parameter still function as expected

• Make tune command able to invoke macros

• The dvswitch.sh tune command/AB now supports invocation of AB macros using the same syntax (*) as DVSM/pyUC

dvswitch.sh

• Inherit dir names from environment

• Along with the variable support in AB, dvswitch.sh can now use AB_DIR, MMDVM_DIR and NODE_DIR from the environment

• Use awk and not jq

• On small machines (older Raspberry Pi) using jq would choke on large database files (DMR)
• We moved bac to using awk which performs MUCH better and does not choke

• Change ASL validation to a more visible node

• Allow several commands to execute without ABInfo being present.

• Add download and validation of user database files.

• Support new AB commands reloadDatabase, AGC settings, etc

MB:

• Change DMR networks on the fly.

• The DMR tune command now support network selection.
• The tune syntax. is PPPPP@AAAAA:###:OOOO
• Where
• PPPPP is the password for the DMR server
• AAAA is the. FQDN (ip address) of the server
• #### is the port that the DMR server is listening on
• OOOO is any options that may be needed (XLX and DMR+)

• Comma delimited set of transmit ports for each mode.

• This will take a whole post to describe!  Maybe even two
• The transmit ports in DVSWITCH.INI now take a comma delimited list of ports
• These ports will allow you to set up single instance bridges with like mode partners with greater than two networks
• NXDN remote command error silence (Just a bug fix)
• DSTAR remote command was dropping into END_TX case. (just a bug fix)

• Better error message for dvswitch.ini file parsing.

• When an error. is found while parsing the ini files, a better error message is generated

• DMR support for talker alias. DVSWITCH.ini has a new tag (TalkerAlias) in the DMR section.

• This setting will be transmitted to the network on each transmission and can include your name, rig, location, etc

• P25 Soft Id transmit and receive

• Still a work in progress, but it is functional on decode

• YSF split of narrow and wide TLV export to support transcode.

• Wide mode YSF packets can now be sent to its own list of transmit ports using TXWidePort
• This is independent of the narrow transmit ports
• This allows you to transcode one side of YSF while keeping the other format free from conversion

• YSF uses the latitude and longitude from MMDVM_Bridge.ini for the GPS location.

• All transmissions will include GPS locations from the MB.ini file if non-zero

• DSTAR slow data fix DSTAR ini file addition: message
• Force MB to begin transmission if we did not see one (FCS bug)
• Make MB return MMDVM and not _Unknown
