Is there an updated timeline for 5e? I can only find the third edition timeline, so my group is missing 15 years...

Sixth World Almanac from 4th ed has the timeline up to 2072 or so, IIRC. Not all the way to present, but close.

any idea why they didnt put one in the 5th ed book?

Best guess?
Page count. The CRB is already a pretty thick book. To throw in an update of all the 'wacky' that had happened, even just from '72 to '75 would have added another 5 to 8 pages.

And that would also cut into the next almenac book as well.

The 5e core seems to assume that anyone reading it has played SR before and understands the setting history. This is evident by what I and many others consider to be a pretty awful setting and history chapter that doesn't do near enough to give new players insight as to how the world is the way it is. I think this is one of the biggest mistakes a game can make, assuming most or all consumers have existing knowledge. It can alienate a lot of people, and it's never good business practice for newcomers to need to buy basically useless books from a dead edition just to grok the setting.

I cannot think of a valid reason for the important and detailed history of Shadowrun to have been presented this way for a brand new edition, or needing to seek out a corollary product like Storm Front to understand the narrative changes between the default setting times of 4th and 5th (which was, what, about 5 years difference)?

TL;DR: they didn't put one in the core book because 5e is plagued with bad decisions

Apparently I missed some books in 5th edition. I've only got a timeline I know down to 2075, not 76 or 77.
