Creating a release

• ensure travis and appveyor is green (Usually the case these days) for the release branch 0-19, 0-20, etc

• test if Nimble works with new version

• Update the version in system.nim

• Update the changelog (put the release date, copy it to e.g. changelog_0_20_0.md)

• Tag the release, e.g. git tag -am "Version 0.15.0" v0.15.0

• Push the tag: git push origin [tagname]

• Nightlies now build the binaries for us: https://github.com/nim-lang/nightlies/releases

• Ensure nightly builds exist

• Recompile koch!

• Generate the full docs; koch doc0 (not koch doc); copy the docs from upload/$nimversion not from docs/html! Otherwise the GA code would be missing!

• Merge 0-19 branch into master

• Update csources via koch pushcsources

Website

• Download the binaries from https://github.com/nim-lang/nightlies/releases
• Rename the nim-$version_windows_(x32/x64).zip files to nim-$version(x32/x64).zip for consistency with every older release.
• Rename the nim-$version_osx.tar.xz to nim-$version.tar.xz as that is what we use for the source based installation.
• Upload the produced .zips. For example: scp nim-0.18.0.tar.xz username@servername:/var/www/nim-lang.org/download/nim-0.18.0.tar.xz (change the version obviously)

Generating the sha256's

• ssh username@servername
• cd /var/www/nim-lang.org/download/
• export NIM_VER=<current_ver> (for example export NIM_VER=0.19.0).
• sh checksums.sh

Updating the blog/downloads page

• Create a new blog post in _drafts titled: version-<ver>-released.md where <ver> is the version without any dots, e.g. 0180 for 0.18.0.
• When ready to release:
  • move the blog post into _posts, making sure to append the current date to its filename: 2017-09-31-title.md.
  • modify config.yml's version key to the new version
  • git commit
    • TIP: Here is a real-life example of a commit that signifies a release: https://github.com/nim-lang/website/commit/6f95916dee1212dcf5465d74dcff14e01f714503. The draft blog post was created in earlier commits, but hopefully it's pretty easy to figure out how it was made.
    • TIP2: You can see what a draft post looks like by running jekyll serve --drafts inside the website's jekyll directory.
  • git push live master (the live remote is a strict secret)

Uploading docs

• export NIM_VER=<current_ver> (for example export NIM_VER=0.19.0).
• Upload documentation to /var/www/nim-lang.org/$NIM_VER
• Change docs symlink
  • cd /var/www/nim-lang.org/
  • ln -sfn $NIM_VER docs (change the version here)
  • Verify this worked using ls -la | grep "docs"

Updating choosenim's channels

Choosenim currently only supports gz so you will need to create a .tar.gz out of the .tar.xz:

• export NIM_VER=<current_ver>
• cd /var/www/nim-lang.org/download
• cp nim-$NIM_VER.tar.xz nim-"$NIM_VER"_copy.tar.xz
• unxz nim-"$NIM_VER"_copy.tar.xz
• gzip --best nim-"$NIM_VER"_copy.tar
• mv nim-"$NIM_VER"_copy.tar.gz nim-"$NIM_VER".tar.gz
• sha256sum nim-"$NIM_VER".tar.gz > nim-"$NIM_VER".tar.gz.sha256

Update the stable channel:

• Update /var/www/nim-lang.org/channels using your favourite editor
  • vim /var/www/nim-lang.org/channels/stable
