--- layout: default title: Publish parent: Release & Milestone Tasks grand_parent: Contributors nav_order: 90 --- # Publish {: .no_toc } ## Contents {: .no_toc .text-delta } 1. TOC {:toc}OnlineDemosHowToUpdate --- ## Create a release branch in GitHub Once the branch is created, only changes necessary for the target release are merged in from the trunk. --- ## Upgrade LocaleExplorer and other demos/samples ... to the ICU project site. Build the icu-demos module following the README's. Update code and/or docs as needed. "Reference" platforms for icu-demos are: RedHat Linux and win32. On Linux, icu-demos is built against the "make install "'ed ICU. So, run ICU4C's configure with --prefix=/some/where pointing to where ICU4C should be installed, and also follow icu-demos's README. Install the new locale explorer and other demos/samples onto the public demo hosting site. --- ## ICU Collation Demo Update the ICU collation demo's `index.html` with the new ICU version’s available collators. 1. Do a clean build (configure, make clean, make install, make check). 1. Otherwise, the data build may not pick up a new locale into the coll/res_index.txt file. 2. Run [icu-demos > webdemo/collation/build.sh](https://github.com/unicode-org/icu-demos/blob/main/webdemo/collation/build.sh) (after modifying it for your system). 3. Copy-paste the output `available-collators.txt` into `index.html`. 1. Or, easier: Use a GUI difftool (e.g., meld) to compare the two and move the changes into index.html. 2. `meld webdemo/collation/index.html ../available-collators.txt` 4. See for example the changes for [ICU-11355](https://unicode-org.atlassian.net/browse/ICU-11355) For details see the comments at the start of the build.sh file. --- ## Repository Branch and Tags ⚠ Careful! The following examples contain specific version, revision and ticket numbers. Adjust them for the current release! Easiest: Paste into an editor, fix, then paste into the terminal. ### Creating Maintenance Branch. Sanity check: Update to the latest repository revision. (Main branch if you copy from main, maintenance branch if you copy from there.) ```sh git checkout main git pull upstream main git log -n1 commit bcd0... (HEAD -> main, upstream/main, ...) ``` Ensure that your local branch is in sync with the upstream branch. Make sure you are checking the upstream remote, and not your fork! Build & test ICU4C & ICU4J on your machine. Create the maintenance branch from the current known good main ref. ```sh git checkout -b maint/maint-63 git push -u upstream maint/maint-63 ``` #### Tagging Use the GitHub GUI to create both the "release" and the "tag" at the same time: Fill in the tag name, such as "release-63-rc" or "release-63-1", and make the target the "maint/maint-xx" branch (such as maint/maint-63). Set the title to "ICU 63 RC" or "ICU 63.1". Fill in the description using the text from the announcement email. (You can also look at previous releases and possibly re-use some of the generic text, such as links to the API docs, etc.) Your screen should look like this: ![image](maint-63-rc-screenshot.png) For the release candidate tag, please check the box that says "Pre-Release". We no longer need to add the note about Git LFS files, as GitHub now includes them in the auto-generated .zip downloads. Click the "Publish Release" button to make the tag. Note: The "latest" tag is no longer updated. It was agreed by the ICU-TC to be deleted around the 64.2 time-frame, as it doesn't work well with with Git. (You need to force-push the new tag, and if somebody has already cloned the repository, they might have something different for the "latest" tag). A possible future alternative might be a sym-link folder, or HTTP redirect that points to the latest release. #### Maintenance release Create the maintenance release tag from the maintenance branch, as above. Update the "latest" tag. ### ~~ICU 58 and earlier~~ ~~Tag related svn files, for **icu**, **icu4j** and (for final releases) **tools** file trees. We tag the tools tree so that we can reproduce the Unicode tools that were used for the Unicode data files in this release.~~ ~~For a Release Candidate, just tag, don't branch, and only tag icu & icu4j.~~ ~~For the final release, branch then tag. Copy the trunk to maint/maint-4-8 and copy that to tags/release-4-8. Specify the source revision explicitly via -r so that you don't inadvertently pick up an unexpected changeset. Make sure that the trunk at the source revision is good.~~ ~~We do not tag the data & icu-demos trees. Steven Loomis writes on 2011-may-23:~~ > ~~My thought had been (in the CVS days) to take a 'snapshot' of these items. > However, in SVN all you need is a date or a revision number (such as > r30140).~~ > ~~So, probably, we don't need to tag these two (idu-demos or data).~~ > ~~Tools are more important because those tools are actually used in the > release.~~ ### Create ICU download page Create the download page before the first milestone, if we have one, or before the release candidate. Log into the ICU homepage Google Site. (If you don't have write access, ask one of the editors to grant you access.) Verify that there is not already a page for the upcoming release: Either via the sitemap, or on the bottom of the main download page where it says something like "Subpages (27): View All". Copy the download page for the last release: Go to that page, gear menu, Copy page; "Name your page" using just the major version number for now (e.g., "61") so that the page URL is just that number, select "Put page under Downloading ICU", click the red COPY button. Adjust the new page as needed: Change the title to "Download ICU 61 Release Candidate" (with the right version number...), remove contents specific to the previous release, update all version numbers, update all links. Put a big, bold+italics, red warning at the top like "This version has not been released yet. Use it for testing but not in production!" Save the page. It is generally a good idea to save frequently. For further edits, simply go back into edit mode. (Keyboard shortcut 'e' for edit, ctrl+s for save.) Add new contents for the upcoming release: Grab some text from the sibling Unicode and CLDR release notes, look at the proposal status doc for this release, make a pass through the api/enhancement tickets fixed in this release or under reviewing/reviewfeedback. Look at the download pages of the last two releases for templates for things like a Migration Issues section etc. Ask everyone on the team to add stuff & details. **Once the page has been created and various people are invited to edit it, everyone should keep editing short so that the page is not locked for others for long periods of time.** ### Maintenance release For a maintenance release, look at the ICU 60 page which includes 60.2. --- ## Milestone on the main download page We had the following HTML on the main download page for ICU 4.8M1 = 4.7.1: ```html

``` --- ## Upload Release Source / Binaries Download Directories are located at, for example, `icu-project.org:/home/htdocs/ex/files/icu4c/4.4.2` corresponding to Look at previous releases for an example. ### Java Source/Bin: Follow instructions here: [Building ICU4J Release Files](../release-build.md) ### C source/binary: ***WORK IN PROGRESS*** #### Source and Linux Binaries: Important: this step works with Unix make + docker. First, install *docker* and *docker-compose. D*o not proceed until *docker run hello-world* works! ```sh $ git clone https://github.com/unicode-org/icu-docker.git $ cd icu-docker/src $ git clone --branch release-64-rc --depth 1 https://github.com/unicode-org/icu.git $ cd icu $ git lfs fetch $ git lfs checkout $ cd ../.. $ less [README.md](https://github.com/unicode-org/icu-docker/blob/main/README.md)  # Follow these instructions. ``` * Source and binaries are created in ./dist/. * The names [don't match what's needed on output](https://github.com/unicode-org/icu-docker/issues/1) so be sure to rename. **Note:** If you only want to make a source tarball (.tgz/.zip), then you can run \`make dist\`. * This will produce a source tarball and will include a pre-compiled .dat file under icu4c/source/data/in/. * Note: This tarball will also omit all of the data sub-directories containing locale data. * Note that the source is taken from the git repository itself, and not your local checkout. (Thus it will exclude any local uncommitted changes). #### Windows Binary: * Manual process: * Build with MSVC x64 Release. (See the ICU [readme.html](https://github.com/unicode-org/icu/main/blob/icu4c/readme.html) file for details). * Open a command prompt. ``` cd C:\icu\icu4c\ (or wherever you have ICU located). powershell Set-ExecutionPolicy -Scope Process Unrestricted .\packaging\distrelease.ps1 -arch x64 ``` This will produce the file "source\dist\icu-windows.zip", which will need to be renamed before uploading. * For example, the binaries for ICU4C v61.1 generated with VS2017 were named "icu4c-61_1-Win64-MSVC2017.zip". * Note: As of ICU 68, the pre-built binaries use MSVC2019 instead of MSVC2017. * Using the output from the build bots: * Navigate to the GitHub page for the commits on the `maint/maint-` branch. * Ex: https://github.com/unicode-org/icu/commits/maint/maint-64 * Click on the green check mark (✔) on the most recent/last commit. (It might be a red X if the builds failed, hopefully not). * This will open up a pop-up with links to various CI builds. * Click on one of the various links that says "Details" for the Azure CI builds. * This will open up the GitHub overview of the build status.
![image](azure-ci-builds.png)
* Click on the link "View more details on Azure Pipelines" link. * This will take you to the actual Azure CI build page. * On the top right of the page there should be a button titled "Artifacts". Click this and it should show a drop-down with various ZIP files that you can download.
![image](azure-ci-builds-artifacts.png)
* The ZIP may automatically download for you. * However, if you are signed-in to visualstudio.com then you might see a dialog titled "Artifacts explorer". * In this case click on the name, then the "..." button to download the zip file.
![image](azure-ci-builds-artifacts-download.png)
* Download both the x64 (64-bit) and x86 (32-bit) ZIP files. * For each architecture: * Extract the Zip file. (It will have a name like "20190829.6_ICU4C_MSVC_x64_Release.zip"). * Navigate into the folder with the same name. * Rename the file "icu-windows.zip" to the appropriate name: * Ex: The x64 zip for version 64.1 was named "icu4c-64_1-Win64-MSVC2017.zip" * Ex: The x86 zip for version 64.1 was named "icu4c-64_1-Win32-MSVC2017.zip" * Note: Note: As of ICU 68, the pre-built binaries use MSVC2019 instead of MSVC2017. * Note: For RC releases the name looked like this: "icu4c-64rc-Win64-MSVC2017.zip" * ~~AIX Bin:~~ (AIX is broken and ignored for now.) * ~~login to gcc119.fsffrance.org and copy the ICU4C source archive created above to there.~~ * ~~$ gzip -dc icu4c-XXX-src.tgz | tar xf -~~ * ~~$ cd icu~~ * ~~$ PATH=/opt/IBM/xlC/13.1.3/bin:$PATH source/runConfigureICU AIX~~ * ~~(The above command line doesn't actually work, see [ICU Ticket ICU-13639](https://unicode-org.atlassian.net/browse/ICU-13639) for a workaround.)~~ * ~~$ gmake DESTDIR=/tmp/icu releaseDist~~ * ~~That last step will create a directory in **/tmp/icu** - zip that up to make the release.~~ * ~~In case /tmp happens to be full, see the [mailing list archive](https://sourceforge.net/p/icu/mailman/message/36275940/) for advice.~~ #### Output of icuexportdata: This step publishes pre-processed Unicode property data, which may be ingested by downstream clients such as ICU4X. * Using the output from the build bots: * Navigate to the Azure Pipeline `C: Create Artifacts from icuexportdata` and download its single artifact (`icuexportdata_output`) * Unzip the file * Rename the `icuexportdata_tag-goes-here.zip` file to the correct tag (replacing slashes with dashes) ### Signing archives and creating checksums: #### Step 1. PGP files: Sign all archives created above with your own personal PGP key. This creates a file with .asc as the suffix. ```sh $ gpg --armor --detach-sign icu4c-xxx-xxx.zip # To verify $ gpg --verify icu4c-xxx-xxx.zip.asc ``` #### Step 2. MD5 files: Use md5sum or [cfv](http://cfv.sf.net) to create [md5](https://en.wikipedia.org/wiki/MD5) hash sums for three groups of files: * icu4j (all files), * icu4c (source), * icu4c (binaries). Using md5sum to create and verify the checksum files: 
md5sum source1 source2 ... sourceN > icu4c_sources.md5 # To verifymd5sum -c icu4c_sources.md5 
Alternatively, use cfv to create and verify md5 files: ```sh cfv -t md5 -C -f icu-……-src.md5 somefile.zip somefile.tgz … # To verify cfv -f icu-……-src.md5 ``` #### Step 3. SHASUM512.txt Create an additional hash sum file SHASUM512.txt file with: ```sh shasum -a 512 *.zip *.tgz | tee SHASUM512.txt ``` This file should also be GPG signed. Check the .asc with \`gpg verify\`. ### Update the Download Page Gadgets Update the gadgets on the download page to point at the new URL for the binaries. 1. Edit the download page. 2. Click on the Gadget area. 3. Click on the "gear" icon. 4. Update the URL field with the new URL. 1. For example: The ICU4C 63.1 Binaries URL was: #### Check the ICU public site for the new release Make sure that, aside from download pages, homepages, news items, feature lists and feature comparisons, etc. are updated. Upload the new API references. Update the User Guide. #### Update the Trac release number list for ICU4C and ICU4J. <> Update the ICU release number list by going to "Admin>Versions" in Trac, and add the new ICU version. #### Post-release cleanup * Cleanup the milestone in the ICU Trac. Move left over items to future milestones. Close the milestone. * Look for TODO comments in the source code and file new tickets as required. * Delete and retag [latest](http://source.icu-project.org/repos/icu/tags/latest/) (**ONLY** after GA release, including maintenance!) << IS THIS STILL VALID WITH GIT? >> --- ## Update online demos These are the online demos/tools that need to be updated to the latest version. * Be sure to verify that the deployed version is publicly available. Note that updating ICU4C demos online requires Gcloud access. ### ICU4C demos * [Run ICU4C demos](https://icu4c-demos.unicode.org/icu-bin/idnbrowser) * [Demo described here](https://github.com/unicode-org/icu-demos/blob/main/README.md) * [Building and deploying from GCloud](https://github.com/unicode-org/icu-demos//blob/main/README.md) ### ICU4J demos * [Run ICU4J online demos](https://icu4j-demos.unicode.org/icu4jweb/) * [Information on the Java demos and samples](https://icu.unicode.org/home/icu4j-demos) * [Instructions for building and deploying updates](https://github.com/unicode-org/icu-demos/blob/main/icu4jweb/README.md) ### Online information update Collation and [comparison](../../../../charts/comparison/index.md) charts need to be updated. See [charts/Performance & Size](../../../../charts/index.md). ### Old sensitive tickets Unset the "sensitive" flag on old tickets. For example, on tickets that were fixed two or more releases ago. [Sample ticket query for ICU 65, for tickets fixed in 63 or earlier](https://unicode-org.atlassian.net/issues/?jql=project%20%3D%20ICU%20AND%20Level%3DSensitive%20AND%20fixVersion%20not%20in%20(65.1%2C%2064.2%2C%2064.1)%20AND%20status%3DDone). Adjust the fixVersion selection as appropriate. Check the list in the ICU meeting. Check duplicates and fixedbyotherticket! Keep the "sensitive" flag on tickets that were closed as duplicates of other tickets that are not yet fixed or have been fixed only very recently. For removing the flag: * Enter bulk edit. Select all query results. * Uncheck duplicates of unfixed or too-recent tickets. * Edit fields: * Security Level = None * Add label "was_sensitive" * No notification emails * Confirm bulk edit. --- ## Punt tickets Double-check that tickets with commits in this release are closed/fixed. Close as needed. (Hopefully none misticketed at this point...) Then punt remaining tickets marked for this release: 1. In Jira, search for all tickets with Project=ICU, Fix Version=, Status≠Done. 2. Go to Bulk Edit ("..." menu in the upper right corner) 3. Select all 4. Edit fields: 1. Fix Version: replace all with "future" 2. Labels: add "punt" (e.g., "punt63") 3. No email notifications 5. Confirm bulk edit 6. Send a courtesy email to the team with a Jira query URL for the Label="punt" tickets. After punting, please also update the "To-Do for Next ICU Release" widget on Jira. 1. Open 2. Use the drop-down to change the fix version to the next ICU version 3. Click "Save" next to the filter title ## Update readme Update [ICU4C readme.html](https://github.com/unicode-org/icu/main/icu4c/readme.html) and [ICU4J readme.html](https://github.com/unicode-org/icu/main/icu4j/readme.html) before every milestone (GA / RC / Milestone-N). Make sure the following items are up to date. * Release version * Last update date * Description - descriptions for GA, RC and Milesone-N are already included in the readme file. * Comment/uncomment parts as appropriate. * If the readme should remain the same between milestones, we can skip directly to the GA description. Otherwise, pick the right one for the release type. * **Since ICU 67, we have skipped from GA to GA**, without marking & unmarking the readme specifically for the release candidate. * Build steps - make sure supported compiler versions are up to date
