+### Features
+
+- [New Network Monitor](https://github.com/nymtech/nym/pull/4610): Monitors the Nym network by sending itself packages across the mixnet. Network monitor is running two tokio tasks, one manages mixnet clients and another manages monitoring itself. Monitor is designed to be driven externally, via an `HTTP api`. This means that it does not do any monitoring unless driven by something like [`locust`](https://locust.io/). This allows us to tailor the load externally, potentially distributing it across multiple monitors. Includes a dockerised setup for automatically spinning up monitor and driving it with locust.
+    - *Note: NNM is not deployed on mainnet yet!*
+ 
+- [Add get_mixnodes_described to validator_client](https://github.com/nymtech/nym/pull/4725)
+
+- [Remove deprecated mark_as_success and use new disarm](https://github.com/nymtech/nym/pull/4751): Update function name to keep terminology consistent with tokio `CancellationToken DropGuard`.
+
+- [Update peer refresh value](https://github.com/nymtech/nym/pull/4754): `lso` expose the value by moving it to wireguard types, and separate the refresh time to the database sync time, so that more probable and needed actions happen faster (refresh) and more improbable ones don't overload the system (peer suspended or stale)
+~~~admonish example collapsible=true title='Testing steps performed'
+- **Noted** that the constants `DEFAULT_PEER_TIMEOUT` and `DEFAULT_PEER_TIMEOUT_CHECK` have been moved to `common/wireguard-types/src/lib.rs` and are now being used across modules for consistency
+- **Observed** that the `peer_controller.rs` now separates the in-memory updates from the storage sync operations to reduce system load
+- **Identified** that in-memory updates of peer bandwidth usage happen every `DEFAULT_PEER_TIMEOUT_CHECK` (every 5 seconds), while storage updates occur every 5 * `DEFAULT_PEER_TIMEOUT_CHECK` (every 25 seconds)
+ 
+**Checked System Load and Performance:**
+ 
+- **Monitored** system resource usage (CPU, memory, I/O) during the test to assess the impact of the changes
+- **Confirmed** that the separation of in-memory updates and storage syncs resulted in reduced system load, particularly I/O operations, compared to previous versions where storage updates occurred more frequently
+- **Ensured** that the system remained responsive and no performance bottlenecks were introduced
+
+- **Efficiency Improvement:** The separation of in-memory updates and storage syncs effectively reduced unnecessary database writes, improving system efficiency without compromising data accuracy
+~~~
+
+- [Remove duplicate stat count for retransmissions](https://github.com/nymtech/nym/pull/4756)
+
+- [Make gateway latency check generic](https://github.com/nymtech/nym/pull/4759): Replace concrete gateway type with trait in latency check, so we can make use of it in the vpn client.
+~~~admonish example collapsible=true title='Testing steps performed'
+- Initialised new `nym-client` with the `--latency-based-selection` flag and ensured it still works as normal. 
+~~~
+
+- [chore: remove repetitive words](https://github.com/nymtech/nym/pull/4763)
+
+- [Avoid race on ip and registration structures](https://github.com/nymtech/nym/pull/4766): To avoid a state where the ip is being cleared out before the registration is also cleared out, couple the two structures under the same lock, since they are anyway very inter-dependent.
+~~~admonish example collapsible=true title='Testing steps performed'
+1.  - **Checked out** the release/2024.10-wedel branch containing the fix for the race condition on IP and registration structures
+    - **Deployed** the on a controlled test environment to prevent interference
+ 
+2. **Monitored Logs:**
+
+    - **Enabled** debug logging to capture all events
+    - **Monitored** logs in real-time to observe the handling of concurrent registration requests
+    - **Checked** for any error messages, warnings, or indications of race conditions
+ 
+3. **Verified Client Responses:**
+ 
+    - Ensured that all clients received appropriate responses:
+    - Successful registration with assigned IP and registration data
+    - Appropriate error messages if no IPs were available or if other issues occurred
+    - Confirmed that no clients were left in an inconsistent state (e.g., assigned an IP but not fully registered)
+ 
+4. **Validated Normal Operation:**
+    - **Conducted standard registration processes** with individual clients to confirm that regular functionality is unaffected via `nym-vpn-cli`
+    - Ensured that authenticated clients could communicate over the network as expected

+# Making `sqlx` work
+
+Some of the errors encountered and possible solutions.
+
+## `The cargo feature offline has to be enabled to use SQLX_OFFLINE`
+
+Did you enable `offline` **cargo feature** of `sqlx` dependency in your
+`Cargo.toml`?
+
+Also, it may happen if you have a version mismatch beetween
+
+- `sqlx` cargo dependency in `Cargo.toml`
+- `sqlx-cli` installed by cargo
+
+To ensure correct version, do
+
+```
+cargo uninstall sqlx-cli
+cargo install --version <version> sqlx-cli
+```
+
+where `<version>` matches the version of sqlx in your `Cargo.toml`.
+
+## `Error: failed to connect to database: password authentication failed`
+
+If it's in-code, make sure you don't "double authenticate", i.e.
+
+- if username and password are already specified in `DATABASE_URL`
+- then, you don't have to use
+
+```rust
+ConnectOptions::from_str(&database_Url)
+    .username() // unnecessary
+    .password() // unnecessary
+```
+
+If it's outside of code (i.e. when running `cargo check`)
+
+- make sure password doesn't have any special characters that could be
+  interpreted by the command line/shell weirdly, like `$#\` etc.
+
+## Cannot generate `sqlx-data.json`
+
+In order for `sqlx` to generate schema for "offline" work (without DB
+connection), as of `v0.6.3` you first **need an active DB connection**.
+
+So make sure
+
+- DB is running
+- `DATABASE_URL` is set correctly
+- `SQLX_OFFLINE` isn't exported to true
+
+Then run `cargo sqlx prepare`
+
+After you have the file, you can ignore `DATABASE_URL` and terminate the DB
+instance. This file represents the DB schema, so when your migrations change,
+you'll need to re-generate it
+
+Make sure to commit the file to VCS if you want to avoid re-doing this again on
+each machine (e.g. other developers, CI).
+
+## Generated `sqlx-data.json` looks like this
+
+```json
+{
+  "db": "PostgreSQL"
+}
+```
+
+after running `cargo sqlx prepare`
+
+### Similar to:
+
+```
+warning: no queries found; do you have the `offline` feature enabled
+```
+
+### Possible solutions
+
+- does your `sqlx-cli` version match `sqlx` version from `Cargo.toml`?
+- do you have `offline` cargo feature enabled?
+- make sure to `cargo clean` after these updates
+
+## Any many, many more
+
+- `EOF while parsing a value at line`
+- `failed to find data for query`
+
+### Possible solutions
+
+- Usually a DB connection issue
+- Retry everything
+- Throw in a `cargo clean -p <your package>` for good measure
