Haven't been able to find some of the Mangrove Jack's dried strains that I'd used in the past, they seem to have disappeared from the MJ's website too. I also noticed that the packaging has changed to a uniform maroon colour. Turns out that they rebranded, and added some new strains to their range (for a launch in the US this summer it seems - no surprise looking at the new names!).
Here's a list of the rebrands for anyone looking for comparable strains -
M27 Belgian Ale- M29 French Saison
M07 British Ale- M42 New World Strong Ale
M79 Burton Union- M36 Liberty Bell Ale
M03 UK Dark Ale (formally Newcastle Dark Ale) - M15 Empire Ale
I don't see the 'Workhorse M10' yeast in the new range, was a great one for fermenting clean at higher temps (i.e.: during summer), so I'll be grabbing a few packs of that before stocks run out.

M10 is still available. See here for the current strains and their uses (beer styles):

These charts should be up to date.
