Let's welcome brand new look made by Bootstrap 4!
Not only website but also our logo is being flat now.
The new logo uses blue as main color, to be different from original.
For us, it also shows the project has up to a new stage.
We hope that the project will get better and better.
BREAKING CHANGE: The path for users to place their images is renamed.
Logos are saved as new names too. Users should move "pictures" to "images".
Any modifications should suit the Bootstrap 4's standard.
When using sub-directory blog, the 'blogof' not looks so good.
And, there are duplicate 'blog' characters, which making people uncomfortable.
So, for sub-directory blog, use 'blog' instead of 'blogof'.
'blog' is not as a sub folder or type anymore, use 'post' instead.
BREAKING CHANGE: Due to the conflict of 'blog' sub-directory, when go to blog post,
now should use 'blogs/{id}'; but when subdomain mode is on, you can still use 'blog'
to access these blog posts. 'blogof' is no longer used, and you need to inform users
that blog link is changed, to avoid the inaccessbility.
