+
+## v4.2.1 - 2020-03-08
+
+**Important notes**
+
+Due to a datarace the config parameters for the newly added timeout middleware required a change.
+See the [docs](https://echo.labstack.com/middleware/timeout).
+A performance regression has been fixed, even bringing better performance than before for some routing scenarios.
+
+**Fixes**
+
+* Fix performance regression caused by path escaping (#1777, #1798, #1799, aldas)
+* Avoid context canceled errors (#1789, clwluvw)
+* Improve router to use on stack backtracking (#1791, aldas, stffabi)
+* Fix panic in timeout middleware not being not recovered and cause application crash (#1794, aldas)
+* Fix Echo.Serve() not serving on HTTP port correctly when TLSListener is used (#1785, #1793, aldas)
+* Apply go fmt (#1788, Le0tk0k)
+* Uses strings.Equalfold (#1790, rkilingr)
+* Improve code quality (#1792, withshubh)
+
+This release was made possible by our **contributors**:
+aldas, clwluvw, lammel, Le0tk0k, maciej-jezierski, rkilingr, stffabi, withshubh
+
+## v4.2.0 - 2020-02-11
+
+**Important notes**
+
+The behaviour for binding data has been reworked for compatibility with echo before v4.1.11 by
+enforcing `explicit tagging` for processing parameters. This **may break** your code if you 
+expect combined handling of query/path/form params.
+Please see the updated documentation for [request](https://echo.labstack.com/guide/request) and [binding](https://echo.labstack.com/guide/request)
+
+The handling for rewrite rules has been slightly adjusted to expand `*` to a non-greedy `(.*?)` capture group. This is only relevant if multiple asterisks are used in your rules.
+Please see [rewrite](https://echo.labstack.com/middleware/rewrite) and [proxy](https://echo.labstack.com/middleware/proxy) for details.
+
+**Security**
+
+* Fix directory traversal vulnerability for Windows (#1718, little-cui)
+* Fix open redirect vulnerability with trailing slash (#1771,#1775 aldas,GeoffreyFrogeye)
+
+**Enhancements**
+
+* Add Echo#ListenerNetwork as configuration (#1667, pafuent)
+* Add ability to change the status code using response beforeFuncs (#1706, RashadAnsari)
+* Echo server startup to allow data race free access to listener address
+* Binder: Restore pre v4.1.11 behaviour for c.Bind() to use query params only for GET or DELETE methods (#1727, aldas)
+* Binder: Add separate methods to bind only query params, path params or request body (#1681, aldas)
+* Binder: New fluent binder for query/path/form parameter binding (#1717, #1736, aldas)
+* Router: Performance improvements for missed routes (#1689, pafuent)
+* Router: Improve performance for Real-IP detection using IndexByte instead of Split (#1640, imxyb)
+* Middleware: Support real regex rules for rewrite and proxy middleware (#1767)
+* Middleware: New rate limiting middleware (#1724, iambenkay)
+* Middleware: New timeout middleware implementation for go1.13+ (#1743, )
+* Middleware: Allow regex pattern for CORS middleware (#1623, KlotzAndrew)
+* Middleware: Add IgnoreBase parameter to static middleware (#1701, lnenad, iambenkay)
+* Middleware: Add an optional custom function to CORS middleware to validate origin (#1651, curvegrid)
+* Middleware: Support form fields in JWT middleware (#1704, rkfg)
+* Middleware: Use sync.Pool for (de)compress middleware to improve performance (#1699, #1672, pafuent)
+* Middleware: Add decompress middleware to support gzip compressed requests (#1687, arun0009)
+* Middleware: Add ErrJWTInvalid for JWT middleware (#1627, juanbelieni)
+* Middleware: Add SameSite mode for CSRF cookies to support iframes (#1524, pr0head)
+
+**Fixes**

 # Cobra Changelog
 
-## Pending
+## v1.1.3
-* Fix man page doc generation - no auto generated tag when `cmd.DisableAutoGenTag = true` @jpmcb
+
+* **Fix:** release-branch.cobra1.1 only: Revert "Deprecate Go < 1.14" to maintain backward compatibility
+
+## v1.1.2
+
+### Notable Changes
+
+* Bump license year to 2021 in golden files (#1309) @Bowbaq
+* Enhance PowerShell completion with custom comp (#1208) @Luap99
+* Update gopkg.in/yaml.v2 to v2.4.0: The previous breaking change in yaml.v2 v2.3.0 has been reverted, see go-yaml/yaml#670
+* Documentation readability improvements (#1228 etc.) @zaataylor etc.
+* Use golangci-lint: Repair warnings and errors resulting from linting (#1044) @umarcor

+* **Fix:** yaml.v2 2.3.0 contained a unintended breaking change. This release reverts to yaml.v2 v2.2.8 which has recent critical CVE fixes, but does not have the breaking changes. See https://github.com/spf13/cobra/pull/1259 for context.
+* **Fix:** correct internal formatting for go-md2man v2 (which caused man page generation to be broken). See https://github.com/spf13/cobra/issues/1049 for context.
+
+## v1.1.0
+
+### Notable Changes

+## Cobra User Contract
+
+### Versioning
+Cobra will follow a steady release cadence. Non breaking changes will be released as minor versions quarterly. Patch bug releases are at the discretion of the maintainers. Users can expect security patch fixes to be released within relatively short order of a CVE becoming known. For more information on security patch fixes see the CVE section below. Releases will follow [Semantic Versioning](https://semver.org/). Users tracking the Master branch should expect unpredictable breaking changes as the project continues to move forward. For stability, it is highly recommended to use a release.
+
+### Backward Compatibility
+We will maintain two major releases in a moving window. The N-1 release will only receive bug fixes and security updates and will be dropped once N+1 is released.
+
+### Deprecation
+Deprecation of Go versions or dependent packages will only occur in major releases. To reduce the change of this taking users by surprise, any large deprecation will be preceded by an announcement in the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) and an Issue on Github.
+
+### CVE
+Maintainers will make every effort to release security patches in the case of a medium to high severity CVE directly impacting the library. The speed in which these patches reach a release is up to the discretion of the maintainers. A low severity CVE may be a lower priority than a high severity one.
+
+### Communication
+Cobra maintainers will use GitHub issues and the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) as the primary means of communication with the community. This is to foster open communication with all users and contributors.
+
+### Breaking Changes
+Breaking changes are generally allowed in the master branch, as this is the branch used to develop the next release of Cobra.
+
+There may be times, however, when master is closed for breaking changes. This is likely to happen as we near the release of a new version.
+
+Breaking changes are not allowed in release branches, as these represent minor versions that have already been released. These version have consumers who expect the APIs, behaviors, etc, to remain stable during the lifetime of the patch stream for the minor release.
+
+Examples of breaking changes include:
+- Removing or renaming exported constant, variable, type, or function.
+- Updating the version of critical libraries such as `spf13/pflag`, `spf13/viper` etc...
+  - Some version updates may be acceptable for picking up bug fixes, but maintainers must exercise caution when reviewing.
+
+There may, at times, need to be exceptions where breaking changes are allowed in release branches. These are at the discretion of the project's maintainers, and must be carefully considered before merging.
+
+### CI Testing
+Maintainers will ensure the Cobra test suite utilizes the current supported versions of Golang.
+
+### Disclaimer
+Changes to this document and the contents therein are at the discretion of the maintainers.
+None of the contents of this document are legally binding in any way to the maintainers or the users.

 # Generating PowerShell Completions For Your Own cobra.Command
 
-Cobra can generate PowerShell completion scripts. Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
+Please refer to [Shell Completions](shell_completions.md#powershell-completions) for details.
-
-*Note*: PowerShell completions have not (yet?) been aligned to Cobra's generic shell completion support.  This implies the PowerShell completions are not as rich as for other shells (see [What's not yet supported](#whats-not-yet-supported)), and may behave slightly differently.  They are still very useful for PowerShell users.
-
-# What's supported
-
-- Completion for subcommands using their `.Short` description
-- Completion for non-hidden flags using their `.Name` and `.Shorthand`
-
-# What's not yet supported
-
-- Command aliases
-- Required, filename or custom flags (they will work like normal flags)
-- Custom completion scripts

-Please refer to [PowerShell Completions](powershell_completions.md) for details.
+Cobra supports native PowerShell completions generated from the root `cobra.Command`. You can use the `command.GenPowerShellCompletion()` or `command.GenPowerShellCompletionFile()` functions. To include descriptions use `command.GenPowerShellCompletionWithDesc()` and `command.GenPowerShellCompletionFileWithDesc()`. Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.
+
+The script is designed to support all three PowerShell completion modes:
+
+* TabCompleteNext (default windows style - on each key press the next option is displayed)
+* Complete (works like bash)
+* MenuComplete (works like zsh)
+
+You set the mode with `Set-PSReadLineKeyHandler -Key Tab -Function <mode>`. Descriptions are only displayed when using the `Complete` or `MenuComplete` mode.
+
+Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
