v6.0.0-beta.2

v6.0.0-beta.2 release of PowerShellCore

Here are the major changes:

* Support backgrounding of pipelines with ampersand (`&`) (PowerShell#3360)

- Putting `&` at the end of a pipeline will cause the pipeline to be run as a PowerShell job.
- When a pipeline is backgrounded, a job object is returned.
- Once the pipeline is running as a job, all of the standard `*-Job` cmdlets can be used to manage the job.
- Variables (ignoring process-specific variables) used in the pipeline are automatically copied to the job so `Copy-Item $foo $bar &` just works.
- The job is also run in the current directory instead of the user's home directory.
- For more information about PowerShell jobs, see [about_Jobs](https://msdn.microsoft.com/en-us/powershell/reference/6/about/about_jobs).

* Engine updates and fixes

- Crossgen more of the .NET Core assemblies to improve PowerShell Core startup time. (PowerShell#3787)
- Enable comparison between a `SemanticVersion` instance and a `Version` instance that is constructed only with `Major` and `Minor` version values.
This will fix some cases where PowerShell Core was failing to import older Windows PowerShell modules. (PowerShell#3793) (Thanks to @mklement0!)

* General cmdlet updates and fixes

- Support Link header pagination in web cmdlets (PowerShell#3828)
- For `Invoke-WebRequest`, when the response includes a Link header we create a RelationLink property as a Dictionary representing the URLs and `rel` attributes and ensure the URLs are absolute to make it easier for the developer to use.
- For `Invoke-RestMethod`, when the response includes a Link header we expose a `-FollowRelLink` switch to automatically follow `next` `rel` links until they no longer exist or once we hit the optional `-MaximumFollowRelLink` parameter value.
- Update `Get-ChildItem` to be more in line with the way that the *nix `ls -R` and the Windows `DIR /S` native commands handle symbolic links to directories during a recursive search.
Now, `Get-ChildItem` returns the symbolic links it encountered during the search, but it won't search the directories those links target. (PowerShell#3780)
- Fix `Get-ChildItem` to continue enumeration after throwing an error in the middle of a set of items.
This fixes some issues where inaccessible directories or files would halt execution of `Get-ChildItem`. (PowerShell#3806)
- Fix `ConvertFrom-Json` to deserialize an array of strings from the pipeline that together construct a complete JSON string.
This fixes some cases where newlines would break JSON parsing. (PowerShell#3823)
- Enable `Get-TimeZone` for macOS/Linux. (PowerShell#3735)
- Change to not expose unsupported aliases and cmdlets on macOS/Linux. (PowerShell#3595) (Thanks to @iSazonov!)
- Fix `Invoke-Item` to accept a file path that includes spaces on macOS/Linux. (PowerShell#3850)
- Fix an issue where PSReadline was not rendering multi-line prompts correctly on macOS/Linux. (PowerShell#3867)
- Fix an issue where PSReadline was not working on Nano Server. (PowerShell#3815)

v6.0.0-beta.1

v6.0.0-beta.1 release of PowerShellCore

Here are the major changes:

* Move to .NET Core 2.0 (.NET Standard 2.0 support)

PowerShell Core has moved to using .NET Core 2.0 so that we can leverage all the benefits of .NET Standard 2.0. (PowerShell#3556)
To learn more about .NET Standard 2.0, there's some great starter content [on Youtube](https://www.youtube.com/playlist?list=PLRAdsfhKI4OWx321A_pr-7HhRNk7wOLLY), on [the .NET blog](https://blogs.msdn.microsoft.com/dotnet/2016/09/26/introducing-net-standard/), and [on GitHub](https://github.com/dotnet/standard/blob/master/docs/faq.md).
We'll also have more content soon in our [repository documentation](https://github.com/PowerShell/PowerShell/tree/master/docs) (which will eventually make its way to [official documentation](https://github.com/powershell/powershell-docs)).
In a nutshell, .NET Standard 2.0 allows us to have universal, portable modules between Windows PowerShell (which uses the full .NET Framework) and PowerShell Core (which uses .NET Core).
Many modules and cmdlets that didn't work in the past may now work on .NET Core, so import your favorite modules and tell us what does and doesn't work in our GitHub Issues!

* Telemetry

- For the first beta of PowerShell Core 6.0, telemetry has been to the console host to report two values (PowerShell#3620):
  - the OS platform (`$PSVersionTable.OSDescription`)
  - the exact version of PowerShell (`$PSVersionTable.GitCommitId`)

If you want to opt-out of this telemetry, simply delete `$PSHome\DELETE_ME_TO_DISABLE_CONSOLEHOST_TELEMETRY`.
Even before the first run of Powershell, deleting this file will bypass all telemetry.
In the future, we plan on also enabling a configuration value for whatever is approved as part of [RFC0015](https://github.com/PowerShell/PowerShell-RFC/blob/master/1-Draft/RFC0015-PowerShell-StartupConfig.md).
We also plan on exposing this telemetry data (as well as whatever insights we leverage from the telemetry) in [our community dashboard](https://blogs.msdn.microsoft.com/powershell/2017/01/31/powershell-open-source-community-dashboard/).

If you have any questions or comments about our telemetry, please file an issue.

* Engine updates and fixes

- Add support for native command globbing on Unix platforms. (PowerShell#3643)
  - This means you can now use wildcards with native binaries/commands (e.g. `ls *.txt`).
- Fix PowerShell Core to find help content from `$PSHome` instead of the Windows PowerShell base directory. (PowerShell#3528)
  - This should fix issues where about_* topics couldn't be found on Unix platforms.
- Add the `OS` entry to `$PSVersionTable`. (PowerShell#3654)
- Arrange the display of `$PSVersionTable` entries in the following way: (PowerShell#3562) (Thanks to @iSazonov!)
  - `PSVersion`
  - `PSEdition`
  - alphabetical order for rest entries based on the keys
- Make PowerShell Core more resilient when being used with an account that doesn't have some key environment variables. (PowerShell#3437)
- Update PowerShell Core to accept the `-i` switch to indicate an interactive shell. (PowerShell#3558)
  - This will help when using PowerShell as a default shell on Unix platforms.
- Relax the PowerShell `SemanticVersion` constructors to not require 'minor' and 'patch' portions of a semantic version name. (PowerShell#3696)
- Improve performance to security checks when group policies are in effect for ExecutionPolicy. (PowerShell#2588) (Thanks to @powercode)
- Fix code in PowerShell to use `IntPtr(-1)` for `INVALID_HANDLE_VALUE` instead of `IntPtr.Zero`. (PowerShell#3544) (Thanks to @0xfeeddeadbeef)

* General cmdlet updates and fixes

- Change the default encoding and OEM encoding used in PowerShell Core to be compatible with Windows PowerShell. (PowerShell#3467) (Thanks to @iSazonov!)
- Fix a bug in `Import-Module` to avoid incorrect cyclic dependency detection. (PowerShell#3594)
- Fix `New-ModuleManifest` to correctly check if a URI string is well formed. (PowerShell#3631)

* Filesystem-specific updates and fixes

- Use operating system calls to determine whether two paths refer to the same file in file system operations. (PowerShell#3441)
  - This will fix issues where case-sensitive file paths were being treated as case-insensitive on Unix platforms.
- Fix `New-Item` to allow creating symbolic links to file/directory targets and even a non-existent target. (PowerShell#3509)
- Change the behavior of `Remove-Item` on a symbolic link to only removing the link itself. (PowerShell#3637)
- Use better error message when `New-Item` fails to create a symbolic link because the specified link path points to an existing item. (PowerShell#3703)
- Change `Get-ChildItem` to list the content of a link to a directory on Unix platforms. (PowerShell#3697)
- Fix `Rename-Item` to allow Unix globbing patterns in paths. (PowerShell#3661)

* Interactive fixes

- Add Hashtable tab completion for `-Property` of `Select-Object`. (PowerShell#3625) (Thanks to @powercode)
- Fix tab completion with `@{<tab>` to avoid crash in PSReadline. (PowerShell#3626) (Thanks to @powercode)
- Use `<id> - <name>` as `ToolTip` and `ListItemText` when tab completing process ID. (PowerShell#3664) (Thanks to @powercode)

* Remoting fixes

- Update PowerShell SSH remoting to handle multi-line error messages from OpenSSH client. (PowerShell#3612)
- Add `-Port` parameter to `New-PSSession` to create PowerShell SSH remote sessions on non-standard (non-22) ports. (PowerShell#3499) (Thanks to @lee303)

* API Updates

- Add the public property `ValidRootDrives` to `ValidateDriveAttribute` to make it easy to discover the attribute state via `ParameterMetadata` or `PSVariable` objects. (PowerShell#3510) (Thanks to @indented-automation!)
- Improve error messages for `ValidateCountAttribute`. (PowerShell#3656) (Thanks to @iSazonov)
- Update `ValidatePatternAttribute`, `ValidateSetAttribute` and `ValidateScriptAttribute` to allow users to more easily specify customized error messages. (PowerShell#2728) (Thanks to @powercode)

v6.0.0-alpha.18

v6.0.0-alpha.18 release of PowerShellCore

Here are the major changes:

* Progress Bar

We made a number of fixes to the progress bar rendering and the `ProgressRecord` object that improved cmdlet performance and fixed some rendering bugs on non-Windows platforms.

- Fix a bug that caused the progress bar to drift on Unix platforms. (PowerShell#3289)
- Improve the performance of writing progress records. (PowerShell#2822) (Thanks to @iSazonov!)
- Fix the progress bar rendering on Unix platforms. (PowerShell#3362) (PowerShell#3453)
- Reuse `ProgressRecord` in Web Cmdlets to reduce the GC overhead. (PowerShell#3411) (Thanks to @iSazonov!)

* Cmdlet updates

- Use `ShellExecute` with `Start-Process`, `Invoke-Item`, and `Get-Help -Online` so that those cmdlets use standard shell associations to open a file/URI.
  This means you `Get-Help -Online` will always use your default browser, and `Start-Process`/`Invoke-Item` can open any file or path with a handler.
  (Note: there are still some problems with STA threads.) (PowerShell#3281, partially fixes PowerShell#2969)
- Add `-Extension` and `-LeafBase` switches to `Split-Path` so that you can split paths between the filename extension and the rest of the filename. (PowerShell#2721) (Thanks to @powercode!)
- Implement `Format-Hex` in C# along with some behavioral changes to multiple parameters and the pipeline. (PowerShell#3320) (Thanks to @MiaRomero!)
- Add `-NoProxy` to web cmdlets so that they ignore the system-wide proxy setting. (PowerShell#3447) (Thanks to @TheFlyingCorpse!)
- Fix `Out-Default -Transcript` to properly revert out of the `TranscribeOnly` state, so that further output can be displayed on Console. (PowerShell#3436) (Thanks to @PetSerAl!)
- Fix `Get-Help` to not return multiple instances of the same help file. (PowerShell#3410)

* Interactive fixes

- Enable argument auto-completion for `-ExcludeProperty` and `-ExpandProperty` of `Select-Object`. (PowerShell#3443) (Thanks to @iSazonov!)
- Fix a tab completion bug that prevented `Import-Module -n<tab>` from working. (PowerShell#1345)

* Cross-platform fixes

- Ignore the `-ExecutionPolicy` switch when running PowerShell on non-Windows platforms because script signing is not currently supported. (PowerShell#3481)
- Standardize the casing of the `PSModulePath` environment variable. (PowerShell#3255)

* JEA fixes

- Fix the JEA transcription to include the endpoint configuration name in the transcript header. (PowerShell#2890)
- Fix `Get-Help` in a JEA session. (PowerShell#2988)
