3-5: LGTM! Changelog entry accurately reflects the PR objectives.

The changelog entry for version 2.14.0 correctly describes the fix for the memory leak issue related to CancellationTokenSource, which aligns with the PR objectives.

There's a minor typo in the changelog entry. The word "Fixed" is repeated. Consider removing one instance:

 ## [2.14.0] - 2024-09-30
 ### Fixed
-- Fixed small memory leak with CancellationTokenSource by adding dispose to the end of the Task.
++ Small memory leak with CancellationTokenSource fixed by adding dispose to the end of the Task.

(ENGLISH_WORD_REPEAT_RULE)


1-6: Consider adding blank lines between version entries for improved readability.

The changelog follows a consistent format and provides clear information about each version. To further enhance readability, consider adding a blank line between each version entry. This will make it easier for readers to distinguish between different versions at a glance.

Example:

## [2.14.0] - 2024-09-30
### Fixed
- Small memory leak with CancellationTokenSource fixed by adding dispose to the end of the Task.

## [2.13.0] - 2024-09-05
### Fixed
- Fixed issue with certain SFTP servers which did not use IsRegularFile property on files by modifying the logic to check that the file is not anything else than a regular file.

163-164: Consider throwing a more specific exception instead of a generic Exception

Throwing a generic Exception can make error handling less precise for consumers of this method. Consider throwing a more specific exception type or creating a custom exception class to provide clearer context about the failure, which can aid in debugging and exception handling.

11-11: Version update looks good.

The version has been correctly updated from 2.13.0 to 2.14.0, which aligns with the PR objectives mentioning the upcoming release version [2.14.0].


Line range hint 1-48: Verify the relation between project file changes and the memory leak fix.

The changes in this project file (version update and SSH.NET package update) don't directly address the memory leak issue related to CancellationTokenSource mentioned in the PR objectives.

To ensure we're not missing any relevant changes, please run the following script:

#!/bin/bash
# Description: Check for changes related to CancellationTokenSource and memory leak fix

# Test: Search for relevant changes in C# files
rg --type csharp -e "CancellationTokenSource" -e "\.Dispose\(\)" -e "using\s+\(.*CancellationTokenSource" --with-filename --line-number

# Test: Check if there are any other changed files that might contain the fix
git diff --name-only HEAD~1 | grep -vE "\.csproj$"

If no relevant changes are found, please clarify in the PR description how the project file changes relate to the memory leak fix.


Line range hint 35-35: SSH.NET package version updated.

The SSH.NET package has been updated to version 2024.1.0. This could potentially be related to the memory leak fix mentioned in the PR objectives.

To ensure this update is relevant to the memory leak fix, please run the following script:
