Right now you can’t try out an Org2Blog v1.1.0 package from MELPA because it isn’t yet building using Org2Blog’s new recipe. Eventually the pull request will get merged. Once it does I will push the changes. However, you can still try out v1.1.0 using a package.
If you’ve been waiting to try Org2Blog v1.1.0 using a package then you can download it here just download the tar file. After downloading it you can install it from Emacs by typing M-x package-install-file and then choosing the file org2blog-master.tar you just downloaded.
The package manager should install the required packages but if it doesn’t it will warn you and you can manually install them. Depending on how you configured package-archives and package-archive-priorities everything should go just fine. Let me know if it doesn’t.
Checkout the README.org now included within the package.
Happy blogging
