It hasn't been that long ago that we saw a BlackBerry World update for BlackBerry 10, or even an update to BlackBerry Bridge. However, updates have dropped for both apps. If you haven't got the notification already, there is an update for both BlackBerry World and BlackBerry Bridge on BlackBerry 10.
The BlackBerry World update goes to v22.214.171.124 and brings about performance and stability improvements. Hopefully, that includes better notifications for app updates, as I still find these hit and miss.
The BlackBerry Bridge update goes to v126.96.36.199 and is a little bigger as it now brings SMS to the PlayBook when you are bridged with a BlackBerry 10 device. Definitely something welcome following the last BlackBerry Bridge update in September, which brought BBM to the PlayBook while bridged.
If the update isn't showing yet, try manual refreshing BlackBerry World. It should be pushed soon enough. You can use the link below for BlackBerry Bridge too.
