# Making a Release

1. Pull the latest master branch of the `daml` repository and create a new branch off it.

   Bump the version number in the `VERSION` file.
   In `docs/source/support/release-notes.rst`, add a new header and label for
   the new version. (See previous releases as examples.)

   Retrieve the new release notes using the command

      `./unreleased.sh <revision range>`

   where `<revision range>` refers to all commits since the last release.
   For example, if the previous release was `v0.13.36` then use the range `v0.13.36..`
   to refer to all commits since that release tag.
   (See `man gitrevisions` for the full syntax of revision ranges.)

   This command outputs each change individually with its appropriate section.
   You need to group them into sections in the `release-notes.rst` file.
   (Again, see previous releases for examples.)

   The changelog may also specify edits to existing changelog additions.
   These are reported with the `WARNING` tag, for example:

       CHANGELOG_BEGIN

       WARNING: fix typo in entry "Adds new amdin API to upload DAR files" with the following.

       - [Sandbox] Adds new admin API to upload DAR files

       CHANGELOG_END

   You will need to manually incorporate such edits to the changelog.

   Once this is done, create a Github pull request (PR) with the above changes
   to the `VERSION` and `release-notes.rst` files.
   It is important that your PR changes exactly these two files.
   Both files must be modified, even if there are no additional release notes.

1. Get a review and approval on your PR and then merge it into master.

1. Once the CI checks have passed for the corresponding master build, the release
   should be available on Bintray, Maven Central and GitHub, and have a Git tag.
   The release should be visible on GitHub with _prerelease_ status, meaning it's
   not yet ready for users to consume. The release notes should not be defined yet
   and will be adjusted later on. Maven central has a delay of around 20 minutes
   until the new version is visible.

1. Run through the following test plan on one of Linux or MacOS:

   1. Install the new SDK using `curl -sSL https://get.daml.com/ | sh -s X.XX.XX`,
      where `X.XX.XX` is the new version number.
   1. Run `daml version --assistant=yes` and verify that the new version is
      selected as the assistant version and the default version for new projects.
   1. Create a new project with `daml new quickstart quickstart-java`
      and switch to it using `cd quickstart`.
   1. Run `daml start`. Your browser should be opened automatically at
      `http://localhost:7500`. Login as `Alice` and verify that there is
      1 contract and 3 templates. Close the tab and kill `daml start` using `Ctrl-C`.
   1. Run `daml build`.
   1. In 3 separate terminals (since each command will block), run
      1. `daml sandbox --port 6865 --scenario Main:setup .daml/dist/quickstart-0.0.1.dar`
      1. `daml navigator server localhost 6865 --port 7500`
      1. `mvn compile exec:java@run-quickstart`
      > Note: It takes some time for our artifacts to be available on Maven Central. If you try running the last command before the artifacts are available, you will get a "not found" error. Trying to build again _in the next 24h_ will result in:
      > ```
      > Failure to find ... was cached in the local repository, resolution will not be reattempted until the update interval of digitalasset-releases has elapsed or updates are forced
      > ```
      > This is Maven telling you it has locally cached that "not found" result and will consider it valid for 24h. To bypass that and force Maven to try the network call again, add a `-U` option, as in `mvn compile exec:java@run-quickstart -U`. Note that this is required to bypass your local cache of the failure; it will not be required for a user trying to run the quickstart after the artifacts have been published.
   1. Point your browser to `http://localhost:7500`,
      login as `Alice` and verify that there is 1 contract, 3 templates and 1 owned IOU.
   1. Check that `curl http://localhost:8080/iou` returns
      ```
      {"0":{"issuer":"EUR_Bank","owner":"Alice","currency":"EUR","amount":100.0000000000,"observers":[]}}
      ```
   1. Kill all processes.
   1. Run `daml studio --replace=always`.
      This should open VSCode and trigger the DAML extension that's bundled with the new SDK version.
      (The new VSCode extension will not be in the marketplace at this point.)
   1. Open `daml/Main.daml`.
   1. Click on `Scenario results` above `setup` and wait for the scenario results
      to appear.
   1. Add `+` at the end of line 11, after `"Alice"` and confirm you get an
      error in line 12.
   1. Add `1` after the `+` and confirm you get an error in line 11.
   1. Delete the `+1` and the `e` in `Alice` and verify that the scenario results
      are updated to the misspelled name.
   1. Right click on `eurBank` in line 17 and verify that "Go to Definition"
      takes you to the definition in line 14.
   1. Close all files.

1. Run through the following test plan on Windows.
   This is slightly shortened to make testing faster and
   since most issues are not platform specific.

   1. Close any running SDK instance in PowerShell (Navigator or Sandbox).
   1. Download and run the Windows installer (the `.exe` file) from
      `https://github.com/digital-asset/daml/releases`.
   1. If asked if you want to remove an existing installation, click `Yes`.
   1. Open a new PowerShell.
   1. Run `daml new quickstart` to create a new project
      and switch to it using `cd quickstart`.
   1. Run `daml start`.
   1. Open your browser at `http://localhost:7500`, verify that you
      can login as Alice and there is one template and one contract.
   1. Kill `daml start` with `Ctrl-C`.
   1. Run `daml studio --replace=always` and open `daml/Main.daml`.
      Verify that the scenario result appears within 30 seconds.
   1. Add `+` at the end of line 26 after `"Alice"` and verify that you get an error.

1. If there are no issues, the release can be made public.
   Go to [the releases page](https://github.com/digital-asset/daml/releases)
   and click on the `Edit` button for the new release.
   Combine the release notes from `docs/source/support/release-notes.rst`
   for all releases since the last public release, convert them from RST to
   Markdown format, and insert them in the textbox.
   Uncheck the `This is a pre-release` checkbox at the bottom and click
   `Update release`.

1. Now go back to your original release PR on Github.
   Add the label `Standard-Change` and leave a comment like
   "All manual tests have passed".

1. Finally, announce the release on the relevant internal Slack channels.
   An announcement on the external Slack channel linking to our blog should appear
   automatically.

1. Documentation is published automatically once the release is public on Github,
   however it takes up to an hour to complete.

Thanks for making a release!
