- GitHub account with access to solidity, solc-js, solc-bin, solidity-website.
- DockerHub account with push rights to the
solc
image. - Launchpad (Ubuntu One) account with a membership in the "Ethereum" team and
a gnupg key for your email in the
ethereum.org
domain (has to be version 1, gpg2 won't work). - Ubuntu/Debian dependencies of the PPA scripts:
devscripts
,debhelper
,dput
,git
,wget
,ca-certificates
. - npm Registry account added as a collaborator for the
solc
package. - Access to the solidity_lang Twitter account.
- Reddit account that is at least 10 days old with a minimum of 20 comment karma (
/r/ethereum
requirements).
At least a day before the release:
- Run
make linkcheck
from withindocs/
and fix any broken links it finds. Ignore false positives caused byhref
anchors and dummy links not meant to work. Note: In order to run the link check, make sure you've built the docs first viadocs.sh
. - Double-check that the most recent docs builds at readthedocs succeeded.
- Make sure that all merged PRs that should have changelog entries do have them.
- Rerun CI on the top commits of main branches in all repositories that do not have daily activity by creating a test branch or PR:
-
solc-js
-
solc-bin
(make sure the bytecode comparison check did run)
-
- (Optional) Create a prerelease in our Ubuntu PPA by following the steps in the PPA section below on
develop
rather than on a tag. This is recommended especially when dealing with PPA for the first time, when we add a new Ubuntu version or when the PPA scripts were modified in this release cycle. - Verify that the release tarball of
solc-js
works. Bump version locally, addsoljson.js
from CI, build it, compare the file structure with the previous version, install it locally and try to use it. - Review Learning from Past Releases to make sure you don't repeat the same mistakes.
At least a day before the release:
- Create a draft PR to sort the changelog.
- Create draft PRs to bump version in
solidity
andsolc-js
. Note: Thesolc-js
PR won't pass CI checks yet because it depends on the soljson binary fromsolc-bin
. - Create a draft of the release on github.
- Create a draft PR to update soliditylang.org.
- Create drafts of blog posts.
- Prepare drafts of Twitter, Reddit and Solidity Forum announcements.
- Create a post on solidity-website in the
Releases
category and explain some of the new features or concepts. - Create a post on solidity-website in the
Security Alerts
category in case of important bug(s). - Get the posts reviewed and approved before the release starts.
- Sort the changelog entries alphabetically and correct any errors you notice. Commit it.
- Update the changelog to include a release date.
- Run
scripts/update_bugs_by_version.py
to regeneratebugs_by_version.json
from the changelog andbugs.json
. Make sure that the resultingbugs_by_version.json
has a new, empty entry for the new version. - Commit changes, create a pull request and wait for the tests. Then merge it.
- Copy the changelog into the release blog post.
- Create a release on GitHub.
Set the target to the
develop
branch and the tag to the new version, e.g.v0.8.5
. Include the following warning:**The release is still in progress. You may see broken links and binaries may not yet be available from all sources.**
. Do not publish it yet - click theSave draft
button instead. - Thank voluntary contributors in the GitHub release notes.
Use
scripts/list_contributors.sh v<previous version>
to get initial list of names. Remove different variants of the same name manually before using the output. - Check that all tests on the latest commit in
develop
are green. - Click the
Publish release
button on the release page, creating the tag. Important: Must not be done before all the PRs, including changelog cleanup and date, are merged. - Wait for the CI runs on the tag itself.
- Switch to the tag that archives have to be created for.
- Create the
prerelease.txt
file: (echo -n > prerelease.txt
). - Run
scripts/create_source_tarball.sh
while being on the tag to create the source tarball. This will create the tarball in a directory calledupload
. - Take the tarball from the upload directory (its name should be
solidity_x.x.x.tar.gz
, otherwiseprerelease.txt
was missing in the step before) and upload the source tarball to the release page. - Take the
github-binaries.tar
tarball fromc_release_binaries
run of the tagged commit in circle-ci and add all binaries from it to the release page. Make sure it contains four binaries:solc-windows.exe
,solc-macos
,solc-static-linux
andsoljson.js
. - Take the
solc-bin-binaries.tar
tarball fromc_release_binaries
run of the tagged commit in circle-ci and add all binaries from it to solc-bin. - Run
npm install
if you've got a clean checkout of the solc-bin repo. - Run
npm run update -- --reuse-hashes
insolc-bin
and verify that the script has updatedlist.js
,list.txt
andlist.json
files correctly and that symlinks to the new release have been added insolc-bin/wasm/
andsolc-bin/emscripten-wasm32/
. - Create a pull request in solc-bin and merge.
- Update the version and the hash (
sha256sum solidity_$VERSION.tar.gz
) in thesolidity
formula in Homebrew core repository.
- Run
./scripts/docker_deploy_manual.sh v$VERSION
.
- Create
.release_ppa_auth
at the root of your local Solidity checkout and setLAUNCHPAD_EMAIL
andLAUNCHPAD_KEYID
to your key's email and key id. - Double-check that the
DISTRIBUTIONS
list inscripts/release_ppa.sh
andscripts/deps-ppa/static_z3.sh
contains the most recent versions of Ubuntu. - Make sure the
~ethereum/cpp-build-deps
PPA repository containslibz3-static-dev
builds for all current versions of Ubuntu. Note that it may be included in thez3-static
multipackage (follow theView package details
link to check). If not present, runscripts/deps-ppa/static_z3.sh
and wait for the builds to succeed before continuing. - Run
scripts/release_ppa.sh v$VERSION
to create the PPA release. This will create a single package containing static binary for older Ubuntu versions in the~ethereum/ethereum-static
PPA and separate packages with dynamically-linked binaries for recent versions (those listed inDISTRIBUTIONS
) in the~ethereum/ethereum
PPA. - Wait for the build to be finished and published for all architectures (currently we only build for
amd64
, but we may addarm
in the future). SERIOUSLY: DO NOT PROCEED EARLIER!!! - After the package with the static build is published, use it to create packages for older Ubuntu versions.
Copy the static package to the
~ethereum/ethereum
PPA for the destination seriesTrusty
,Xenial
andBionic
while selectingCopy existing binaries
.
- Wait until solc-bin was properly deployed. You can test this via remix - a test run through remix is advisable anyway.
- Increment the version number, create a pull request for that, merge it after tests succeeded.
- Create a tag using
git tag --annotate v$VERSION
and push it withgit push --tags
. - Wait for the CI runs on the tag itself.
- Take the
solc-x.y.z.tgz
artifact frombuild-package
run on the tagged commit in circle-ci. Inspect the tarball to ensure that it contains an up-to-date compiler binary (soljson.js
). - Run
npm publish solc-x.y.z.tgz
to publish the newly created tarball.
- Make sure the documentation for the new release has been published successfully. Go to the documentation status page at ReadTheDocs and verify that the new version is listed, works and is marked as default.
- Remove "still in progress" warning from the release notes.
- Merge the blog posts related to the release.
- Create a commit to increase the version number on
develop
inCMakeLists.txt
and add a new skeleton changelog entry. - Update the release information section in the source of soliditylang.org.
- Announce on Twitter, including links to the release and the blog post.
- Announce on Fosstodon, including links to the release and the blog post.
- Share the announcement on Reddit in
/r/ethdev
, cross-posted to/r/ethereum

Announcements
category. - Share the announcement on Project Updates
- Share the announcement on
#solidity
channel on Matrix - Share the announcement on

- If anything went wrong this time, mention it in Learning from Past Releases.
- Lean back, wait for bug reports and repeat from step 1 :).
