Rebrand cleanups: getpeerinfo help example + 1.0.3 debian changelog entry

net.cpp: getpeerinfo help address example 18030->21768 and 'Hush server'->'DragonX server'. debian/changelog: prepend 1.0.3 release entry summarizing IBD speedups, witness fix, bulk streaming, seed phrases, assumeutxo removal. NOTE net.cpp change needs a daemon rebuild to surface in runtime RPC help. Staged on 176; not pushed.

+    * No GUI currently utilizes this but that feature is planned for SD
+    * The donation has extremely good privacy:
+      * It cannot be determined from public blockchain data if a donation is being made, as it takes the place of a Sietch output
+      * It cannot be determined from public blockchain data the amount of the donation
+      * Donations do not create new transactions, do not use additional blockspace and cannot be detected by anyone but the sender or reciever
+  * New HAC option `ac_clearnet` can be used to disable clearnet networking for an entire blockchain instead of just a single node
+  * Updated test framework and tests which allowed the fixing of the `z_sendmany` bug above
+  * Faster compiling of RandomX internals
+  * GMP dependency removed, as it is no longer needed
+  * Hush is now compatible with GCC15 and now correctly supports customizing the compiler for a build via the CC env var
+  * New HTML man pages are now available at doc/man/hushd.html and doc/man/hush-cli.html
+
 hush (3.10.4) stable; urgency=medium
 
   * Updated seed node list

+##            Quick Primer on addnode vs connect            ##
+##  Let's say for instance you use addnode=4.2.2.4          ##
+##  addnode will connect you to and tell you about the      ##
+##    nodes connected to 4.2.2.4.  In addition it will tell ##
+##    the other nodes connected to it that you exist so     ##
+##    they can connect to you.                              ##
+##  connect will not do the above when you 'connect' to it. ##
+##    It will *only* connect you to 4.2.2.4 and no one else.##
+##                                                          ##
+##  So if you're behind a firewall, or have other problems  ##
+##  finding nodes, add some using 'addnode'.                ##
+##                                                          ##
+##  If you want to stay private, use 'connect' to only      ##
+##  connect to "trusted" nodes.                             ##
+##                                                          ##
+##  If you run multiple nodes on a LAN, there's no need for ##
+##  all of them to open lots of connections.  Instead       ##
+##  'connect' them all to one node that is port forwarded   ##
+##  and has lots of connections.                            ##
+##       Thanks goes to [Noodle] on Freenode.               ##

+
+First set it up as follows:
+* Copy dragonxd.service to the systemd user directory, which is /usr/lib/systemd/user directory
+
+## Basic Usage
+
+How to start the script:
+`systemctl start --user dragonxd.service`
+
+How to stop the script:
+`systemctl stop --user dragonxd.service`
+
+How to restart the script:
+`systemctl restart --user dragonxd.service`
+
+## How to watch it as it starts
+
+Use the following on most Linux distros:
+`watch systemctl status --user dragonxd.service`
+
+Or watch the log directly:
+`tail -f ~/.hush/DRAGONX/debug.log`
+
+## Troubleshooting
+
+* Don't run it with sudo or root, or it won't work with the wallet.

-# Hush 3.10.5 ""
+# Hush 3.10.5 "Atelic Alpaca"
 
 This is an OPTIONAL but RECOMMENDED upgrade.
 
+  * DragonX is no longer supported by this codebase
+    * DragonX devs have forked our code and we wish them the best
+    * Find the latest place to download a DragonX full node via dragonx.is
   * Concurrent `z_sendmany` now works
     * A longstanding bug relating to run multiple `z_sendmany` operations at
       once has been fixed. You can now queue up many `z_sendmany` operations
       and they will succeed because they now understand how to avoid spending
       coins that another `z_sendmany` process is trying to spend.
+  * Updated Autonomous System Map (asmap)
   * New RPC `z_listlockunspent`
     * Lists shielded notes (coins inside a zaddr) which are temporarily unspendable because an RPC process is currently trying to spend them.
     * If that operation succeeds, they will become spent. If it fails they will be unlocked and become spendable again.
-  * Fixed DragonX checkpoints
+  * New option to `z_shieldcoinbase` allows privately donating a percentage of coinbase funds during shielding
-    * Hush checkpoints were mistakenly listed as checkpoints in the 3.10.4
+    * This new option defaults to OFF and allows CLI users to opt-in to donating between 0% and 10% of coinbase funds to developers
-     release, which caused some nodes to be unable to sync.
+    * No GUI currently utilizes this but that feature is planned for SD
-    * This release fixes this issue.
+    * The donation has extremely good privacy:
+      * It cannot be determined from public blockchain data if a donation is being made, as it takes the place of a Sietch output
+      * It cannot be determined from public blockchain data the amount of the donation
+      * Donations do not create new transactions, do not use additional blockspace and cannot be detected by anyone but the sender or reciever
+  * New HAC option `ac_clearnet` can be used to disable clearnet networking for an entire blockchain instead of just a single node
   * Updated test framework and tests which allowed the fixing of the `z_sendmany` bug above
   * Faster compiling of RandomX internals
+  * GMP dependency removed, as it is no longer needed
+  * Hush is now compatible with GCC15 and now correctly supports customizing the compiler for a build via the CC env var
+  * New HTML man pages are now available at doc/man/hushd.html and doc/man/hush-cli.html
