4 Before every release candidate:
6 * Update translations (ping wumpus on IRC) see [translation_process.md](https://github.com/bitcoin/bitcoin/blob/master/doc/translation_process.md#synchronising-translations).
8 * Update manpages, see [gen-manpages.sh](https://github.com/bitcoin/bitcoin/blob/master/contrib/devtools/README.md#gen-manpagessh).
10 Before every minor and major release:
12 * Update [bips.md](bips.md) to account for changes since the last release.
13 * Update version in `configure.ac` (don't forget to set `CLIENT_VERSION_IS_RELEASE` to `true`)
14 * Write release notes (see below)
15 * Update `src/chainparams.cpp` nMinimumChainWork with information from the getblockchaininfo rpc.
16 * Update `src/chainparams.cpp` defaultAssumeValid with information from the getblockhash rpc.
17 - The selected value must not be orphaned so it may be useful to set the value two blocks back from the tip.
18 - Testnet should be set some tens of thousands back from the tip due to reorgs there.
19 - This update should be reviewed with a reindex-chainstate with assumevalid=0 to catch any defect
20 that causes rejection of blocks in the past history.
22 Before every major release:
24 * Update hardcoded [seeds](/contrib/seeds/README.md), see [this pull request](https://github.com/bitcoin/bitcoin/pull/7415) for an example.
25 * Update [`BLOCK_CHAIN_SIZE`](/src/qt/intro.cpp) to the current size plus some overhead.
26 * Update `src/chainparams.cpp` chainTxData with statistics about the transaction count and rate.
27 * Update version of `contrib/gitian-descriptors/*.yml`: usually one'd want to do this on master after branching off the release - but be sure to at least do it before a new major release
29 ### First time / New builders
31 If you're using the automated script (found in [contrib/gitian-build.sh](/contrib/gitian-build.sh)), then at this point you should run it with the "--setup" command. Otherwise ignore this.
33 Check out the source code in the following directory hierarchy.
35 cd /path/to/your/toplevel/build
36 git clone https://github.com/bitcoin-core/gitian.sigs.git
37 git clone https://github.com/bitcoin-core/bitcoin-detached-sigs.git
38 git clone https://github.com/devrandom/gitian-builder.git
39 git clone https://github.com/bitcoin/bitcoin.git
41 ### Bitcoin maintainers/release engineers, suggestion for writing release notes
43 Write release notes. git shortlog helps a lot, for example:
45 git shortlog --no-merges v(current version, e.g. 0.7.2)..v(new version, e.g. 0.8.0)
47 (or ping @wumpus on IRC, he has specific tooling to generate the list of merged pulls
48 and sort them into categories based on labels)
50 Generate list of authors:
52 git log --format='%aN' "$*" | sort -ui | sed -e 's/^/- /'
54 Tag version (or release candidate) in git
56 git tag -s v(new version, e.g. 0.8.0)
58 ### Setup and perform Gitian builds
60 If you're using the automated script (found in [contrib/gitian-build.sh](/contrib/gitian-build.sh)), then at this point you should run it with the "--build" command. Otherwise ignore this.
62 Setup Gitian descriptors:
65 export SIGNER=(your Gitian key, ie bluematt, sipa, etc)
66 export VERSION=(new version, e.g. 0.8.0)
68 git checkout v${VERSION}
71 Ensure your gitian.sigs are up-to-date if you wish to gverify your builds against other Gitian signatures.
77 Ensure gitian-builder is up-to-date:
79 pushd ./gitian-builder
83 ### Fetch and create inputs: (first time, or when dependency versions change)
85 pushd ./gitian-builder
87 wget -P inputs https://bitcoincore.org/cfields/osslsigncode-Backports-to-1.7.1.patch
88 wget -P inputs http://downloads.sourceforge.net/project/osslsigncode/osslsigncode/osslsigncode-1.7.1.tar.gz
91 Create the OS X SDK tarball, see the [OS X readme](README_osx.md) for details, and copy it into the inputs directory.
93 ### Optional: Seed the Gitian sources cache and offline git repositories
95 By default, Gitian will fetch source files as needed. To cache them ahead of time:
97 pushd ./gitian-builder
98 make -C ../bitcoin/depends download SOURCES_PATH=`pwd`/cache/common
101 Only missing files will be fetched, so this is safe to re-run for each build.
103 NOTE: Offline builds must use the --url flag to ensure Gitian fetches only from local URLs. For example:
105 pushd ./gitian-builder
106 ./bin/gbuild --url bitcoin=/path/to/bitcoin,signature=/path/to/sigs {rest of arguments}
109 The gbuild invocations below <b>DO NOT DO THIS</b> by default.
111 ### Build and sign Bitcoin Core for Linux, Windows, and OS X:
113 pushd ./gitian-builder
114 ./bin/gbuild --num-make 2 --memory 3000 --commit bitcoin=v${VERSION} ../bitcoin/contrib/gitian-descriptors/gitian-linux.yml
115 ./bin/gsign --signer $SIGNER --release ${VERSION}-linux --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-linux.yml
116 mv build/out/bitcoin-*.tar.gz build/out/src/bitcoin-*.tar.gz ../
118 ./bin/gbuild --num-make 2 --memory 3000 --commit bitcoin=v${VERSION} ../bitcoin/contrib/gitian-descriptors/gitian-win.yml
119 ./bin/gsign --signer $SIGNER --release ${VERSION}-win-unsigned --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-win.yml
120 mv build/out/bitcoin-*-win-unsigned.tar.gz inputs/bitcoin-win-unsigned.tar.gz
121 mv build/out/bitcoin-*.zip build/out/bitcoin-*.exe ../
123 ./bin/gbuild --num-make 2 --memory 3000 --commit bitcoin=v${VERSION} ../bitcoin/contrib/gitian-descriptors/gitian-osx.yml
124 ./bin/gsign --signer $SIGNER --release ${VERSION}-osx-unsigned --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-osx.yml
125 mv build/out/bitcoin-*-osx-unsigned.tar.gz inputs/bitcoin-osx-unsigned.tar.gz
126 mv build/out/bitcoin-*.tar.gz build/out/bitcoin-*.dmg ../
129 Build output expected:
131 1. source tarball (`bitcoin-${VERSION}.tar.gz`)
132 2. linux 32-bit and 64-bit dist tarballs (`bitcoin-${VERSION}-linux[32|64].tar.gz`)
133 3. windows 32-bit and 64-bit unsigned installers and dist zips (`bitcoin-${VERSION}-win[32|64]-setup-unsigned.exe`, `bitcoin-${VERSION}-win[32|64].zip`)
134 4. OS X unsigned installer and dist tarball (`bitcoin-${VERSION}-osx-unsigned.dmg`, `bitcoin-${VERSION}-osx64.tar.gz`)
135 5. Gitian signatures (in `gitian.sigs/${VERSION}-<linux|{win,osx}-unsigned>/(your Gitian key)/`)
137 ### Verify other gitian builders signatures to your own. (Optional)
139 Add other gitian builders keys to your gpg keyring, and/or refresh keys.
141 gpg --import bitcoin/contrib/gitian-keys/*.pgp
144 Verify the signatures
146 pushd ./gitian-builder
147 ./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-linux ../bitcoin/contrib/gitian-descriptors/gitian-linux.yml
148 ./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-win-unsigned ../bitcoin/contrib/gitian-descriptors/gitian-win.yml
149 ./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-osx-unsigned ../bitcoin/contrib/gitian-descriptors/gitian-osx.yml
154 Commit your signature to gitian.sigs:
157 git add ${VERSION}-linux/${SIGNER}
158 git add ${VERSION}-win-unsigned/${SIGNER}
159 git add ${VERSION}-osx-unsigned/${SIGNER}
161 git push # Assuming you can push to the gitian.sigs tree
164 Codesigner only: Create Windows/OS X detached signatures:
165 - Only one person handles codesigning. Everyone else should skip to the next step.
166 - Only once the Windows/OS X builds each have 3 matching signatures may they be signed with their respective release keys.
168 Codesigner only: Sign the osx binary:
170 transfer bitcoin-osx-unsigned.tar.gz to osx for signing
171 tar xf bitcoin-osx-unsigned.tar.gz
172 ./detached-sig-create.sh -s "Key ID"
173 Enter the keychain password and authorize the signature
174 Move signature-osx.tar.gz back to the gitian host
176 Codesigner only: Sign the windows binaries:
178 tar xf bitcoin-win-unsigned.tar.gz
179 ./detached-sig-create.sh -key /path/to/codesign.key
180 Enter the passphrase for the key when prompted
181 signature-win.tar.gz will be created
183 Codesigner only: Commit the detached codesign payloads:
185 cd ~/bitcoin-detached-sigs
186 checkout the appropriate branch for this release series
188 tar xf signature-osx.tar.gz
189 tar xf signature-win.tar.gz
191 git commit -m "point to ${VERSION}"
192 git tag -s v${VERSION} HEAD
193 git push the current branch and new tag
195 Non-codesigners: wait for Windows/OS X detached signatures:
197 - Once the Windows/OS X builds each have 3 matching signatures, they will be signed with their respective release keys.
198 - Detached signatures will then be committed to the [bitcoin-detached-sigs](https://github.com/bitcoin-core/bitcoin-detached-sigs) repository, which can be combined with the unsigned apps to create signed binaries.
200 Create (and optionally verify) the signed OS X binary:
202 pushd ./gitian-builder
203 ./bin/gbuild -i --commit signature=v${VERSION} ../bitcoin/contrib/gitian-descriptors/gitian-osx-signer.yml
204 ./bin/gsign --signer $SIGNER --release ${VERSION}-osx-signed --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-osx-signer.yml
205 ./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-osx-signed ../bitcoin/contrib/gitian-descriptors/gitian-osx-signer.yml
206 mv build/out/bitcoin-osx-signed.dmg ../bitcoin-${VERSION}-osx.dmg
209 Create (and optionally verify) the signed Windows binaries:
211 pushd ./gitian-builder
212 ./bin/gbuild -i --commit signature=v${VERSION} ../bitcoin/contrib/gitian-descriptors/gitian-win-signer.yml
213 ./bin/gsign --signer $SIGNER --release ${VERSION}-win-signed --destination ../gitian.sigs/ ../bitcoin/contrib/gitian-descriptors/gitian-win-signer.yml
214 ./bin/gverify -v -d ../gitian.sigs/ -r ${VERSION}-win-signed ../bitcoin/contrib/gitian-descriptors/gitian-win-signer.yml
215 mv build/out/bitcoin-*win64-setup.exe ../bitcoin-${VERSION}-win64-setup.exe
216 mv build/out/bitcoin-*win32-setup.exe ../bitcoin-${VERSION}-win32-setup.exe
219 Commit your signature for the signed OS X/Windows binaries:
222 git add ${VERSION}-osx-signed/${SIGNER}
223 git add ${VERSION}-win-signed/${SIGNER}
225 git push # Assuming you can push to the gitian.sigs tree
228 ### After 3 or more people have gitian-built and their results match:
230 - Create `SHA256SUMS.asc` for the builds, and GPG-sign it:
233 sha256sum * > SHA256SUMS
236 The list of files should be:
238 bitcoin-${VERSION}-aarch64-linux-gnu.tar.gz
239 bitcoin-${VERSION}-arm-linux-gnueabihf.tar.gz
240 bitcoin-${VERSION}-i686-pc-linux-gnu.tar.gz
241 bitcoin-${VERSION}-x86_64-linux-gnu.tar.gz
242 bitcoin-${VERSION}-osx64.tar.gz
243 bitcoin-${VERSION}-osx.dmg
244 bitcoin-${VERSION}.tar.gz
245 bitcoin-${VERSION}-win32-setup.exe
246 bitcoin-${VERSION}-win32.zip
247 bitcoin-${VERSION}-win64-setup.exe
248 bitcoin-${VERSION}-win64.zip
250 The `*-debug*` files generated by the gitian build contain debug symbols
251 for troubleshooting by developers. It is assumed that anyone that is interested
252 in debugging can run gitian to generate the files for themselves. To avoid
253 end-user confusion about which file to pick, as well as save storage
254 space *do not upload these to the bitcoin.org server, nor put them in the torrent*.
256 - GPG-sign it, delete the unsigned file:
258 gpg --digest-algo sha256 --clearsign SHA256SUMS # outputs SHA256SUMS.asc
261 (the digest algorithm is forced to sha256 to avoid confusion of the `Hash:` header that GPG adds with the SHA256 used for the files)
262 Note: check that SHA256SUMS itself doesn't end up in SHA256SUMS, which is a spurious/nonsensical entry.
264 - Upload zips and installers, as well as `SHA256SUMS.asc` from last step, to the bitcoin.org server
265 into `/var/www/bin/bitcoin-core-${VERSION}`
267 - A `.torrent` will appear in the directory after a few minutes. Optionally help seed this torrent. To get the `magnet:` URI use:
269 transmission-show -m <torrent file>
271 Insert the magnet URI into the announcement sent to mailing lists. This permits
272 people without access to `bitcoin.org` to download the binary distribution.
273 Also put it into the `optional_magnetlink:` slot in the YAML file for
274 bitcoin.org (see below for bitcoin.org update instructions).
276 - Update bitcoin.org version
278 - First, check to see if the Bitcoin.org maintainers have prepared a
279 release: https://github.com/bitcoin-dot-org/bitcoin.org/labels/Releases
281 - If they have, it will have previously failed their Travis CI
282 checks because the final release files weren't uploaded.
283 Trigger a Travis CI rebuild---if it passes, merge.
285 - If they have not prepared a release, follow the Bitcoin.org release
286 instructions: https://github.com/bitcoin-dot-org/bitcoin.org#release-notes
288 - After the pull request is merged, the website will automatically show the newest version within 15 minutes, as well
289 as update the OS download links. Ping @saivann/@harding (saivann/harding on Freenode) in case anything goes wrong
291 - Announce the release:
293 - bitcoin-dev and bitcoin-core-dev mailing list
295 - Bitcoin Core announcements list https://bitcoincore.org/en/list/announcements/join/
297 - bitcoincore.org blog post
299 - Update title of #bitcoin on Freenode IRC
301 - Optionally twitter, reddit /r/Bitcoin, ... but this will usually sort out itself
303 - Notify BlueMatt so that he can start building [the PPAs](https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin)
305 - Archive release notes for the new version to `doc/release-notes/` (branch `master` and branch of the release)
307 - Create a [new GitHub release](https://github.com/bitcoin/bitcoin/releases/new) with a link to the archived release notes.
