{{% 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 [URL-safe unpadded
Base64](/appendices/#url-safe-unpadded-base64).

Event IDs are still prefixed with `$` and might result in looking like
`$Rqnc-F-dvnEYJTyHq_iKxU2bZ1CI92-kuZq3a5lr5Zg`.
Clarify event format text in room version specs (#3501) Split the text about event IDs and event formats into separate sections. This is largely to make it easier to link to, but I think the resulting text makes more sense too. 2021-11-19 12:05:52 +01:00			`---`

Fix the table of content for room versions (#1884) * Fix ToC for room versions pages Like for the cs-module shortcode, use .RenderShortcodes instead of .Content for the rver-fragment shortcode, so the headings are detected by Hugo. Signed-off-by: Kévin Commaille <zecakeh@tedomum.fr> * Change the way "this version" is detected in added-in and changed-in shortcodes 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.

Update documentation style & fix room version heading order (#3683) * Update documentation style & fix room version heading order Also add a missing signing key section to v6. This additionally contains various edits to the fragments to have them make a little bit more sense in context. Finally, this updates various aspects of the documentation style which haven't previously been considered - they're added here considering we're in the area. * changelog * enhanced changelogs * Minor wording adjustments * Apply suggestions from code review Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com> 2022-01-31 23:18:58 +01:00			Event IDs are still prefixed with `$` and might result in looking like
