Now that we use .RenderShortcodes in the rver-fragment shortcode, we cannot remove the output of these shortcodes dynamically because they are replaced by a temporary placeholder due to Hugo's internals. Instead, since the `this` parameter was only used for room version, we always use the `v` parameter and compare with the version provided in the page's front matter.

{{% added-in v=4 %}} The event ID is the [reference
|
|
hash](/server-server-api#calculating-the-reference-hash-for-an-event) of
|
|
the event encoded using a variation of [Unpadded
|
|
Base64](/appendices#unpadded-base64) which replaces the 62nd and
|
|
63rd characters with `-` and `_` instead of using `+` and `/`. This
|
|
matches [RFC4648's definition of URL-safe
|
|
base64](https://tools.ietf.org/html/rfc4648#section-5).
|
|
|
|
Event IDs are still prefixed with `$` and might result in looking like
|
|
`$Rqnc-F-dvnEYJTyHq_iKxU2bZ1CI92-kuZq3a5lr5Zg`.
