+**Reminder Bot Update 1.3.0**
+
+- `help` command reworked:
+  + The help command now shows all information within Discord, rather than redirecting to an external website
+  + The help command has separate pages for different commands with examples, and detailed information on arguments
+
+- `timezone` command reworked:
+  + Timezone was a notoriously annoying and confusing command to use, so these changes will hopefully improve its usability
+  + Typing `$timezone` will now show you a list of the most popular timezones and the time in those timezones, to make it easy for many users to select their timezones
+  + If a timezone is not recognised, the bot will show you a list of 'similar' timezones by name, and the times in these timezones
+  + Outputs are more descriptive
+
+- `language` command reworked:
+  + Language has been made to look somewhat nicer and you can now use reactions to respond with what language you wish to switch to
+
+- `timer` visual improvements:
+  + Some emojis have been added to the timer command to make it look nicer
+
+- `look` fixes:
+  + `$look all` has been removed again, as some users pointed out that this was flawed and allowed random users to check reminders in private channels
+  + Fixed a bug where channels would be ignored if other switches were provided to the command
+
+- `remind` command reworked:
+  + Backend of this command completely reworked to be much cleaner code
+  + Fixed providing times in exact format sometimes not working if a day was provided but not a month/year
+  + This command can now be used to bulk-set reminders to multiple locations
+
+- General changes:
+  + More command outputs use embeds to look nicer
+  + Commands that fail provide help outputs that are the same as the help command
+  + Remind commands now provide output that is more detailed. This includes showing the exact errors that occurred for each reminder that couldn't be set, if bulk-setting reminders
+  + Translations are now loaded from a JSON file included within the executable, which should be faster
+  + Reduced user caching by individually querying some attributes like language and timezone
