* `show_reactions`: Let favourites and emoji reactions be viewed through the API (default: `true`).
* `password_reset_token_validity`: The time after which reset tokens aren't accepted anymore, in seconds (default: one day).
## :database
* `improved_hashtag_timeline`: Setting to force toggle / force disable improved hashtags timeline. `:enabled` forces hashtags to be fetched from `hashtags` table for hashtags timeline. `:disabled` forces object-embedded hashtags to be used (slower). Keep it `:auto` for automatic behaviour (it is auto-set to `:enabled` [unless overridden] when HashtagsTableMigrator completes).
## Background migrations
* `populate_hashtags_table/sleep_interval_ms`: Sleep interval between each chunk of processed records in order to decrease the load on the system (defaults to 0 and should be keep default on most instances).
* `populate_hashtags_table/fault_rate_allowance`: Max rate of failed objects to actually processed objects in order to enable the feature (any value from 0.0 which tolerates no errors to 1.0 which will enable the feature even if hashtags transfer failed for all records).
## Welcome
* `direct_message`: - welcome message sent as a direct message.
* `enabled`: Enables the send a direct message to a newly registered user. Defaults to `false`.
