Previous version of the talk I used v0.12, which was clearly labeled as a preview version for research purposes.
v1.0 uses a complete rewrite of the patch format, amongst other things.
A few months after the release of Pijul 0.12, a user reported a defect regarding the unrecording of patches that were previously involved in a conflict.
After some time a solution was found, but it meant that a new patch format was needed, along with a few new algorithms.
So, Pijul had to be rewritten from scratch to make it all work, which obviously resulted in a lot of breaking changes.

Let's introduce another one, while we`re at it!
Your version control system may be supported by a hosting provider, but that doesn't necessarily mean that said hosting provider supports the open-source community.
Lots of hosting providers primarily offer private repositories.
Also, not all version control systems focus as much on supporting open-source development as Git does, for example.

Now at Info Support, besides doing consultancy work, I also teach a few courses.
We offer a wide range of courses.
And they exist mainly to get our junior colleagues up to speed with important concepts or products they'll need for their daily work.
They address base software development topics such as object-orientation, automated testing, continuous delivery, containerisation and so on.

Well, BitKeeper happened.
BitKeeper always was a proprietary piece of software, so a paid product.
But Linux got a special deal.
The deal is simple, the Linux community could use Bitkeeper for free in exchange for some metadata and an agreement for Linux contributors not to work on competing version control systems. 
No other distributed version control systems existed at the time.
Eventually however, in March 2005, Bitkeeper informs teh Linux Kernel Development Team that they will have to start to pay to continue using Bitkeeper.

So **I** thought the year 2005 really stood out in this graphic.
Of course, that doesn't necessarily mean everyone thought so.
In fact, at the end of one particular course day, a student came to me with a question.
And her question proved that she had noticed an **entirely** different thing than I had.
She came to me after class and said: "Git is great and all that, but what's gonna be the **next** big thing?"

"It looks like nothing has happend in Version Control world for over ten years!"
