Use an H2 for changelog entries.

The documentation rule requires sections to start at ##. This new ### 2026-10-20 heading also triggers markdownlint MD001 after # Changelog. Use ## for the date entries, including this entry.

As per coding guidelines, documentation sections start at ##.

[warning] 5-5: Heading levels should only increment by one level at a time

Review comment at @ecosystem/standalone-extensions/posi/changelog.md at line 5:
Update the changelog date-entry heading from H3 to H2 so it starts with ##,
consistent with the required section level after the Changelog heading.

* **listen**: `posix_listen` added, `listen(2)` 1:1, with `SOMAXCONN` registered if absent ([descriptors](/docs/{{version}}/ecosystem/standalone-extensions/posi/api/descriptors-and-paths), [constants](/docs/{{version}}/ecosystem/standalone-extensions/posi/api/constants)). SocketTest 16 passed + 1 skipped on php84, zhp and the Pi. Shipped in tag v0.10.6; `PHP_POSI_VERSION` and the composer.json `version` read 0.10.6, matching the tag.

### 2026-10-14

* **Socket descriptors**: `posix_fileno`, `posix_dup`, `posix_socket_fdopen` added for sharing one listening socket across ext-parallel threads ([descriptors](/docs/{{version}}/ecosystem/standalone-extensions/posi/api/descriptors-and-paths)). Suite 67 passed (66 + 1 skipped on php84, which has no ext-parallel). Shipped in tag v0.10.5; `PHP_POSI_VERSION` and the composer.json `version` read 0.10.6 at that tag.

##### `posix_listen(int $fd, int $backlog): int`

Marks a bound socket as accepting connections. Returns `0`, or `-1` (same semantics as C `listen(2)`). A non-socket fails with `ENOTSOCK`, a datagram socket with `EOPNOTSUPP`.

* `$fd` — a bound `SOCK_STREAM` socket descriptor (TCP or Unix).
* `$backlog` — the queue length for pending connections; `SOMAXCONN` asks for the system maximum.

**Example**

```php
$server = stream_socket_server('unix:///tmp/app.sock', $errno, $error, STREAM_SERVER_BIND);
posix_listen(posix_fileno($server), SOMAXCONN);
$connection = stream_socket_accept($server);
```
