# Release Notes for development

_Generated: 2025-11-14T00:04:02.126Z_

## Overview of new features
5+
6+
- MQTT V5 and transactional communication support with remote servers
7+
- GeoHash routing
8+
- Any configured schema can be converted to any other schema ( limitations apply )
9+
- Inter server fall back routing, allows the server to move to a different server if a connection fails
10+
11+
12+
### [MSG-10](https://mapsmessaging.atlassian.net/browse/MSG-10) — Complete the MQTT-V5 connection logic
13+
14+
The server can now support client side MQTT V5 protocol messages to establish links with other servers
15+
16+
17+
### [MSG-11](https://mapsmessaging.atlassian.net/browse/MSG-11) — Add config to select v3, v4, or v5
18+
19+
By specifying mqtt-v3 or mqtt-v5 for the protocol on the inter server links the user can select which protocol version to use. By specifying just mqtt then the server will attempt to connect using either of them and once connected will use that version
20+
21+
22+
```

```
73+
74+
75+
Also adding, that now we have discovery working the plan is to integrate the discovery manager and the Network Connection Manager so that when the server discovers another messaging server it will pass the details to the Network Connection Manager. If it is configured to be able to auto connect then the server will use the config to establish a connection and either pull/push data depending on the config.
76+
 
77+
So you can have a default config like
78+
79+
80+
81+
```
82+
name: {{hostname}}
83+
url: {{remote_url}}
84+
sessionId: {{auto-generate}}
85+
protocol: {{protocol_defined_in_discovery}}
86+
username: global_username
87+
password: global_token
88+
links:
89+
-
90+
direction: pull
91+
remote_namespace: #
92+
local_namespace: /{{hostname}}/
93+
```
94+
95+
96+
This would automatically connect to the discovered host, use the protocol that was being advertised with the username/password being that of the global one for the server. It would then subscribe to all topics and map them to the local namespace under the hostname.
97+
On a maps server it would also get the schemas for the topics and map them locally. Obviously this is a simple example of mapping everything but we can also add selectors, or break up the namespace. If we know its a maps server we can get a list of topics without actually subscribing to the server allowing the server to manage an “has interest” subscription.
98+
99+
100+
### [MSG-12](https://mapsmessaging.atlassian.net/browse/MSG-12) — Add support for transactional event passing
101+
102+
QoS can now be set on each “link” configuration in the NetworkConnectionManager.yaml
103+
104+
If the protocol doesn’t support the 3 different QoS then anything above 0 will be treated as transactional
105+
```
106+

109+
local_namespace: /zeropi05/
110+
remote_namespace: "/device/#"
111+
include_schema: true
112+
qos: 2 # 0, 1 or 2
113+
```
114+
115+
116+
117+
### [MSG-124](https://mapsmessaging.atlassian.net/browse/MSG-124) — Implement a geoHash message router
118+
119+
**Description**
120+
Used for inter server connections to enable events to be routed to a geoHash topic name
121+
122+
123+
### [MSG-134](https://mapsmessaging.atlassian.net/browse/MSG-134) — Event looping occurs when multiple joins to remote and local loop configured
124+
125+
The issue is that the message being delivered via the loop mechanism is being sent back into the engine without a clone being made, this causes the original topic/message to reset and send again, causing a messaging storm.
126+
127+
The loop has been fixed to stop this and a fatal error induced if it happens again
128+
129+
130+
### [MSG-135](https://mapsmessaging.atlassian.net/browse/MSG-135) — Docker script fails to start the server
131+
132+
The change to the lib layout resulted in the startDocker.sh unable to load the main Maps jar. The start script is now inline with the main start.sh script
133+
134+
Do not move the 'www' directory to data, leave in MAPS_HOME
135+
136+
137+
### [MSG-142](https://mapsmessaging.atlassian.net/browse/MSG-142) — Configure a Schema Repository for the server
138+
139+
The server schema support has been modified to remove the storage of the physical schema with the destination storage and into a Schema Repository. Currently only file is supported, in future this will encompase XRegistry and other Maps rest servers.
140+
141+
142+
Configurable schema repo ( currently file only supported ) when we get XRegistry we can add it or others
143+
Upgrade from previous version of schema
144+
Support for schema to schema data conversion
145+
regex topic name mapping for schemas, ( avoids adding a schema for each topic can map topics to a single schema )
146+
More validation and tests of data coming in to the schema
147+
More validation and tests in the server around schemas
148+
New SchemaManager.yaml file to configure the schema repository
149+
150+
151+
### [MSG-40](https://mapsmessaging.atlassian.net/browse/MSG-40) — Improve storage behavior when running OOM (literally or via corrupt file)
152+
153+
Fixed issues with the storage layer when changing configuration resulted in corruption of existing stores for that destination
154+
Add better exception handling in low memory environments
155+
Rename corrupted files for later processing
156+
157+
158+
### [MSG-73](https://mapsmessaging.atlassian.net/browse/MSG-73) — Concurrent modification logged
159+
160+
The concurrent exception arose while the restapi attempted to get the number of events for a specific destination. This was a long running function. The function is now very lightweight and avoids the same paths as an active server
161+
162+
163+
### [MSG-95](https://mapsmessaging.atlassian.net/browse/MSG-95) — Create release notes automatically
164+
165+
Release notes are not auto generated from github and jira
166+
167+
168+
169+
