This blog post summarizes changes to the vcpkg package manager as part of the 2025.09.17 registry release, the 2025-08-29 and 2025-09-03 tool releases, as well as changes to vcpkg documentation throughout September. This month’s updates includes new binary caching sources x-azcopy and x-azcopy-sas, support for tvOS and watchOS target platforms, and minor improvements and bug fixes.Some stats for this period: There are now 2,673 total ports available in the vcpkg curated registry. A port is a versioned recipe for building a package from source, such as a C or C++ library. 11 new ports were added to the curated registry. 188 ports were updated. As always, we validate each change to a port by building all other ports that depend on or are depended by the library that is being updated for our 15 main triplets. 59 community contributors made commits. The main vcpkg repo has over 7,100 forks and 25,600 stars on GitHub.vcpkg changelog (2025.09.17 release) Added support for tvOS and watchOS target platforms (PR: Microsoft/vcpkg-tool#1747, thanks @wkornewald!). Added two new binary caching sources that interact with Azure Storage blob containers using the azcopy executable: x-azcopy-sas,,[,]: Intended as a drop-in replacement for azblob, it uses SAS tokens for authentication. x-azcopy,[,]: Intended for non-SAS authentication methods like Microsoft Entra ID; requires preloading credentials and/or the AZCOPY_AUTO_LOGIN_TYPE. Internally, we use the azcopy copy --from-to BlobLocal {destination} --include-path {files} argument to download multiple files in a single azcopy job. This improves performance and brings it more in line with azblob, that uses a single curl invocation to download a batch of files. Upload happens one file at a time in the background. (PR: Microsoft/vcpkg-tool#1738) Added a new option --dereference-symlinks to vcpkg export. This copies symlinks as regular files and directories in the exported results, which can be useful to continuous integration systems needing to restore vcpkg’s install tree (PR: Microsoft/vcpkg-tool#1705). Added new vcpkg.json property: configuration. This is an alias for the vcpkg-configuration property, allowing you to embed vcpkg configuration properties that would otherwise have been specified in a separate vcpkg-configuration.json file (PR: Microsoft/vcpkg-tool#1766). Added installed package files to SPDX SBOM files generated by vcpkg and removed repetition of relationships that is no longer present in v3 of the SPDX spec (PR: Microsoft/vcpkg-tool#1744, thanks @ekilmer!). vcpkg no longer restores the original “last updated” times for restored files during binary caching operations on Windows to resolve issues where a build tool is expecting headers and binaries to have similar last updated times but thinks the restored binaries are too old. This was already previously fixed on Linux systems (PR: Microsoft/vcpkg-tool#1750, thanks @autoantwort!). Fixed an issue where vcpkg was failing to detect conflicting installed files when the installed content has capital letters (PR: Microsoft/vcpkg-tool#1768). Other minor improvements and bug fixes.Documentation changes Added documentation for configuration field in vcpkg.json files. (PR: Microsoft/vcpkg-docs#527). Added documentation for --dereference-symlinks option for vcpkg export (PR: Microsoft/vcpkg-docs#524). Added documentation for x-azcopy and x-azcopy-sas binary caching sources (PR: Microsoft/vcpkg-docs#511).If you have any suggestions for our documentation, please submit an issue in our GitHub repo or see the box at the bottom of a particular article.Total ports available for tested tripletstripletports availablex86-windows2463x64-windows2586x64-windows-release2587x64-windows-static2457x64-windows-static-md2514x64-uwp1458arm64-windows2189arm64-windows-static-md2171arm64-uwp1422x64-osx2416arm64-osx2385x64-linux2577arm-neon-android2011x64-android2071arm64-android2035While vcpkg supports a much larger variety of target platforms and architectures (as community triplets), the list above is validated exhaustively to ensure updated ports don’t break other ports in the catalog.Thank you to our contributorsvcpkg couldn’t be where it is today without contributions from our open-source community.
