If you have a package where a lot of people are still using a legacy version of it you might want to keep pushing (security-)fixes to that "branch".

Let's say the "latest" version of your package is "5.4.0", but there is as significant amount of people still using "4.7.4" – the last version you released before doing "5.0.0".

You found a critical bug in "5.4.0" and push it as out as "5.4.1", but it applies to "4.7.4" as well and so you want to do "4.7.5".

Assuming you have semantic-release already set up, you can follow these steps to get that "4.7.5" legacy support release out.

Go to the relevant commit: git checkout v4.7.4
Create a new branch from it: git checkout -b 4.x (You can choose any branch name, just make sure to use the same in step 3)

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

Generate ssh key pairs for accounts and add them to GitHub accounts.

Use curl to get the JSON response for the latest release
Use grep to find the line containing file URL
Use cut and tr to extract the URL
Use wget to download it

curl -s https://api.github.com/repos/jgm/pandoc/releases/latest \
| grep "browser_download_url.*deb" \
| cut -d : -f 2,3 \
| tr -d \" \
