What is SoftEther VPN?

Post-quantum key exchange landed, then the release train went quiet.

SoftEther's 5.x line ships infrequently — six tags spread across 2023 to 2025, most of them merge-commit version bumps with no release notes. The one substantive entry in this window, 5.2.5188, folded liboqs and oqs-provider submodule updates in to add X25519MLKEM768, the NIST hybrid post-quantum key exchange. Everything around it is build plumbing: FreeBSD and macOS CI images, Linux artifact publishing, Docker machinery moved into the main repo.

What is ESPHome?

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

Post-quantum key exchange landed, then the release train went quiet.

◆ Current state

SoftEther's 5.x line ships infrequently — six tags spread across 2023 to 2025, most of them merge-commit version bumps with no release notes. The one substantive entry in this window, 5.2.5188, folded liboqs and oqs-provider submodule updates in to add X25519MLKEM768, the NIST hybrid post-quantum key exchange. Everything around it is build plumbing: FreeBSD and macOS CI images, Linux artifact publishing, Docker machinery moved into the main repo.

◆ Where it's heading

The work is drifting from protocol features toward build and supply-chain hygiene, and the crypto addition arrived through submodule updates rather than in-house design. Release notes are thin enough that several tags credit contributors without describing what changed. With the newest entry now over a year old, this reads as a maintenance-paced project carried by a small group of contributors.

◆ Prediction

If the pattern holds, the next tag is another accumulation of CI and dependency work, with post-quantum defaults tightening as liboqs moves upstream. The entries give no signal of a new protocol or management-plane direction.

ESPHome 2026.9.0 ships template climate component, OTA encryption with API key, and ESP-NOW for ESP32-P4

◆ Current state

ESPHome 2026.9.0 is out, capping a beta cycle that added a template climate component (a long-requested flexible HVAC control primitive), OTA encryption keyed to the device's API key (hardening the update path), and ESP-NOW over hosted shim for the ESP32-P4. The beta cycle also included a systematic RAM allocation safety pass across the codebase — heap exhaustion now returns an error instead of panicking. Monthly releases continue landing at a consistent pace.

◆ Where it's heading

ESPHome is expanding in two directions simultaneously: broader hardware support (ESP32-P4, BK72xx BLE, new platform components) and more robust runtime behavior (RAMAllocator pattern, use-after-free fixes, better BLE-WiFi coexistence). The template climate component is the most user-visible addition — it brings custom HVAC logic into ESPHome's declarative model, reducing the need for external Home Assistant automations. Audio stack (i2s, resampler, mixer) reliability is also a consistent focus.

◆ Prediction

The 2026.10.0 cycle will likely continue the RAMAllocator pattern across remaining allocating code paths and add more ESP32-P4-specific features. Audio (voice assistants, speakers) will stay a top area given the ongoing i2s reliability work.
