We've updated our apps with new cache management options so that Telegram can take up nearly zero space on your phone, even if you‘re using it heavily.

Read about it in the Telegram blog:

In other news, you can now manually reorder your sticker packs, and the order will be synced across all your devices. This can be done in Sticker Settings, accessible via the new button in the sticker panel (or via Settings).

On Android and Desktop, tap/click and hold on a pack to drag it to its new place. On iOS, tap 'Edit' first. Manual reordering is coming to all other official apps within a day.
