SingLinkVPN 2.5 releases at a glance

What the 2.5 series introduced

Chain proxy: use your own IP as the exit

Chain proxy adds a second exit after the SingLinkVPN node: your device → SingLinkVPN node → exit → Internet. You can pick one of the official exits in the app or add your own SOCKS5 proxy IP, so the VPN node and the final public IP are managed separately.

It is not a classic double VPN: when you use your own SOCKS5 exit, the second hop is that SOCKS5 proxy, not a second VPN tunnel. Custom chain proxy arrived on iOS 2.5.1 and Android 2.5.8; under the current plans it is part of Plus and above. For a walkthrough, see mobile chain proxy and custom SOCKS5 exits.

Domain proxy rules

Domain proxy lets you decide per website how traffic goes: domains in Direct Domains use your current network, and domains in Forced Proxy Domains always go through the SingLinkVPN node. It arrived on iOS 2.5.1 and Android 2.5.8 and is part of Plus and above.

IPv6 support

iOS 2.5.1 added IPv6 network connections and Android 2.5.8 added IPv6 proxying, so the apps work on IPv6 and dual-stack networks. Actual results still depend on your carrier, network, node and device.

Sola and Mini

Sola is SingLink’s next-generation in-house VPN transport protocol, rebuilt from the SingLink 2.0 technology stack. It reached macOS in 2.5.7, Windows in 2.5.8 (Sola protocol nodes) and Android in 2.5.8, and the iOS 2.5 apps list Sola in the protocol picker. Sola is available on Plus, Pro, Max and Rich; the Free Plan and Fast do not include it.

Mini was added on Android 2.5.8. It is a disguise layer that runs on top of Beta, Sola or SingLink 2.0 rather than a separate protocol, and it is available on Plus and above.

Widgets, Shortcuts and automatic connection

iOS 2.5.0 introduced a Home Screen widget, Sign in with Apple, multi-device management and more high-speed connection protocols, and the iOS 2.5.1 release notes list widgets and Shortcuts support. Android 2.5.8 added a home screen widget, AI auto-connect (AI Auto SingLink) and smart connection testing.

macOS 2.5 and 2.5.7

macOS was the first platform on 2.5. macOS 2.5 (July 22, 2026) supported both Apple silicon (M-series) and Intel Macs and added:

• Real-time node speed tests and automatic node updates.

• More than 20 new interface languages.

• A 24/7 online support portal inside the app.

• Fixes for connection lag and hard-to-connect nodes reported by the community, and invitation links that update the backup access link automatically.

• SingLink 2.0 protocol nodes for Pro, Max and Rich users.

• A comprehensive security audit and inspection before release.

macOS 2.5.7 (August 19, 2026) moved to one Universal installer for Apple silicon and Intel Macs, added Sola protocol support for Plus, Pro, Max and Rich, improved connection stability and node speed-test accuracy, and fixed other known issues.

At launch, macOS 2.5 raised the daily free data to 1 GB. The Free Plan has changed since: today each device gets 500 MB a day on desktop and 200 MB a day on mobile, and up to 1 GB a day during campaigns (see the Free Plan page).

Windows 2.5.8

Windows 2.5.8 (August 25, 2026) added Sola protocol nodes, fixed crash issues from the previous version, improved the close button, restored the contact support function and raised node connection stability. It shipped after the security and no-logs audits were completed; see the 2.5 security audit and no-logs verification. Its release notes also promised 1 GB of free data every day; the current Free Plan allowance is described above.

Android 2.5.8

Android 2.5.8 (September 3, 2026) was the largest Android update of the series:

• The Sola protocol and the Mini option, plus more nodes.

• Custom chain proxy and custom domain proxy.

• IPv6 proxying.

• A home screen widget, AI auto-connect and smart connection testing.

• Improvements to the live-chat support system, connection performance, UI interactions and subscription plan performance.

• Fixes for known issues from the previous version.

According to the release notes, subscribers on Plus and above saw the largest performance gain over the previous generation.

iOS 2.5.0, 2.5.1 and 2.5.2

• iOS 2.5.0: Home Screen widget, Sign in with Apple, multi-device management and more high-speed connection protocols.

• iOS 2.5.1 (September 4, 2026): custom chain proxy, custom domain proxy, IPv6 network connection support, a wider choice of protocols, widgets and Shortcuts support, an improved live-chat support system and interface fixes. From 2.5.1 on, the App Store version number matches the SingLinkVPN version number.

• iOS 2.5.2 beta (September 14, 2026): improved connection performance; fixed repeated resource loading that could cause crashes, excess heat and unresponsive screens; fixed delayed server switching; improved latency checks, signal indicators and sorting in the server list; fixed support-chat reloads; refined connection status messages.

iOS moved on to 2.6.1 on October 3, 2026, which fixes all issues reported by v2.5 users.

Apple TV 2.5.2

Apple TV 2.5.2 (September 15, 2026) reworked remote navigation for the TV, updated account and subscription controls, device management and the help and support pages, and upgraded the VPN core with the connection and stability work from iOS 2.5.2. It is still the current Apple TV version; update it from the App Store on Apple TV (see the Apple TV download page).

Security checks in the 2.5 series

The 2.5 apps were covered by a third-party security audit and an independent no-logs verification of the production environment, and a September 11, 2026 mobile audit addendum identified Android 2.5.8 (build 5066) and iOS 2.5.1 (build 18). Scope and results are in the 2.5 security audit and no-logs article.

How to move from 2.5 to the latest version

If you are still on a 2.5 build, update to the current release: 2.6.1 on iOS, Android, Windows and macOS, and 2.6 on Linux. Step-by-step instructions for every platform are in the SingLinkVPN 2.6.1 release notes, and the installers are on the download page.
