Bumps [github.com/spf13/cobra](https://github.com/spf13/cobra) from 1.3.0 to 1.4.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/spf13/cobra/releases">github.com/spf13/cobra's releases</a>.</em></p> <blockquote> <h2>v1.4.0</h2> <h1>Winter 2022 Release ❄️</h1> <p>Another season, another release!</p> <h2>Goodbye viper! 🐍 🚀</h2> <p>The core Cobra library no longer requires Viper and all of its indirect dependencies. This means that Cobra's dependency tree has been drastically thinned! The Viper dependency was included because of the <code>cobra</code> CLI generation tool. <a href="https://github.com/spf13/cobra-cli/releases/tag/v1.3.0">This tool has migrated to <code>spf13/cobra-cli</code></a>.</p> <p>It's <em>pretty unlikely</em> you were importing and using <strong>the bootstrapping CLI tool</strong> as part of your application (after all, it's just a tool to get going with core <code>cobra</code>).</p> <p>But if you were, replace occurrences of</p> <pre><code>"github.com/spf13/cobra/cobra" </code></pre> <p>with</p> <pre><code>"github.com/spf13/cobra-cli" </code></pre> <p>And in your <code>go.mod</code>, you'll want to also include this dependency:</p> <pre><code>github.com/spf13/cobra-cli v1.3.0 </code></pre> <p>Again, the maintainers <em>do not anticipate</em> this being a breaking change to users of the core <code>cobra</code> library, so minimal work should be required for users to integrate with this new release. Moreover, this means the dependency tree for your application using Cobra should no longer require dependencies that were inherited from Viper. Huzzah! 🥳</p> <p>If you'd like to read more</p> <ul> <li>issue: <a href="https://github-redirect.dependabot.com/spf13/cobra/issues/1597">spf13/cobra#1597</a></li> <li>PR: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1604">spf13/cobra#1604</a></li> </ul> <h2>Documentation 📝</h2> <ul> <li>Update Go Doc link and badge in README: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1593">spf13/cobra#1593</a></li> <li>Fix to install command, now targets <code>@latest</code>: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1576">spf13/cobra#1576</a></li> <li>Added MAINTAINERS file: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1545">spf13/cobra#1545</a></li> </ul> <h2>Other 💭</h2> <ul> <li>Bumped license year to 2022 in golden files: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1575">spf13/cobra#1575</a></li> <li>Added Pixie to projects: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1581">spf13/cobra#1581</a></li> <li>Updated labeler for new labeling scheme: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1613">spf13/cobra#1613</a> & syntax fix: <a href="https://github-redirect.dependabot.com/spf13/cobra/pull/1624">spf13/cobra#1624</a></li> </ul> <p>Shoutout to our awesome contributors helping to make this cobra release possible!! <a href="https://github.com/spf13"><code>@spf13</code></a> <a href="https://github.com/marckhouzam"><code>@marckhouzam</code></a> <a href="https://github.com/johnSchnake"><code>@johnSchnake</code></a> <a href="https://github.com/jpmcb"><code>@jpmcb</code></a> <a href="https://github.com/liggitt"><code>@liggitt</code></a> <a href="https://github.com/umarcor"><code>@umarcor</code></a> <a href="https://github.com/hiljusti"><code>@hiljusti</code></a> <a href="https://github.com/marians"><code>@marians</code></a> <a href="https://github.com/shyim"><code>@shyim</code></a> <a href="https://github.com/htroisi"><code>@htroisi</code></a></p> </blockquote> </details> <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/spf13/cobra/blob/master/CHANGELOG.md">github.com/spf13/cobra's changelog</a>.</em></p> <blockquote> <h1>Cobra Changelog</h1> <h2>v1.1.3</h2> <ul> <li><strong>Fix:</strong> release-branch.cobra1.1 only: Revert "Deprecate Go < 1.14" to maintain backward compatibility</li> </ul> <h2>v1.1.2</h2> <h3>Notable Changes</h3> <ul> <li>Bump license year to 2021 in golden files (<a href="https://github-redirect.dependabot.com/spf13/cobra/issues/1309">#1309</a>) <a href="https://github.com/Bowbaq"><code>@Bowbaq</code></a></li> <li>Enhance PowerShell completion with custom comp (<a href="https://github-redirect.dependabot.com/spf13/cobra/issues/1208">#1208</a>) <a href="https://github.com/Luap99"><code>@Luap99</code></a></li> <li>Update gopkg.in/yaml.v2 to v2.4.0: The previous breaking change in yaml.v2 v2.3.0 has been reverted, see <a href="https://github-redirect.dependabot.com/go-yaml/yaml/issues/670">go-yaml/yaml#670</a></li> <li>Documentation readability improvements (<a href="https://github-redirect.dependabot.com/spf13/cobra/issues/1228">#1228</a> etc.) <a href="https://github.com/zaataylor"><code>@zaataylor</code></a> etc.</li> <li>Use golangci-lint: Repair warnings and errors resulting from linting (<a href="https://github-redirect.dependabot.com/spf13/cobra/issues/1044">#1044</a>) <a href="https://github.com/umarcor"><code>@umarcor</code></a></li> </ul> <h2>v1.1.1</h2> <ul> <li><strong>Fix:</strong> yaml.v2 2.3.0 contained a unintended breaking change.

Tendermint
Byzantine-Fault Tolerant State Machine Replication. Or Blockchain, for short.
| Branch | Tests | Coverage | Linting |
|---|---|---|---|
| master |
Tendermint Core is a Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine - written in any programming language - and securely replicates it on many machines.
For protocol details, refer to the Tendermint Specification.
For detailed analysis of the consensus protocol, including safety and liveness proofs, read our paper, "The latest gossip on BFT consensus".
Documentation
Complete documentation can be found on the website.
Releases
Please do not depend on master as your production branch. Use releases instead.
Tendermint has been in the production of private and public environments, most notably the blockchains of the Cosmos Network. we haven't released v1.0 yet since we are making breaking changes to the protocol and the APIs. See below for more details about versioning.
In any case, if you intend to run Tendermint in production, we're happy to help. You can contact us over email or join the chat.
More on how releases are conducted can be found here.
Security
To report a security vulnerability, see our bug bounty program. For examples of the kinds of bugs we're looking for, see our security policy.
We also maintain a dedicated mailing list for security updates. We will only ever use this mailing list to notify you of vulnerabilities and fixes in Tendermint Core. You can subscribe here.
Minimum requirements

Quick Start
Contributing
Please abide by the Code of Conduct in all interactions.
Before contributing to the project, please take a look at the contributing guidelines and the style guide. You may also find it helpful to read the specifications, and familiarize yourself with our Architectural Decision Records (ADRs) and Request For Comments (RFCs).
Versioning
Semantic Versioning
Tendermint uses Semantic Versioning to determine when and how the version changes. According to SemVer, anything in the public API can change at any time before version 1.0.0
To provide some stability to users of 0.X.X versions of Tendermint, the MINOR version is used to signal breaking changes across Tendermint's API. This API includes all publicly exposed types, functions, and methods in non-internal Go packages as well as the types and methods accessible via the Tendermint RPC interface.
Breaking changes to these public APIs will be documented in the CHANGELOG.
Upgrades
In an effort to avoid accumulating technical debt prior to 1.0.0, we do not guarantee that breaking changes (ie. bumps in the MINOR version) will work with existing Tendermint blockchains. In these cases you will have to start a new blockchain, or write something custom to get the old data into the new chain. However, any bump in the PATCH version should be compatible with existing blockchain histories.
For more information on upgrading, see UPGRADING.md.
Supported Versions
Because we are a small core team, we only ship patch updates, including security updates, to the most recent minor release and the second-most recent minor release. Consequently, we strongly recommend keeping Tendermint up-to-date. Upgrading instructions can be found in UPGRADING.md.
