What is ESPEasy?

One release a year, each one a filesystem or networking rewrite you must plan for.

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

What is Retool?

Retool puts app testing in public beta a week after its app builder went GA.

Retool's app builder went GA on October 28, building React apps from natural language, coding agents or imported code, with AI spend controls and credit packs alongside. Private npm registries for Enterprise apps and GPT 6.1 Terra followed. On November 3 testing for apps entered public beta, the first quality tool aimed at the apps the builder now produces.

One release a year, each one a filesystem or networking rewrite you must plan for.

◆ Current state

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

◆ Where it's heading

The project's pattern is long test cycles followed by a build that changes something foundational — filesystem, networking, MCU support — and asks users to back up settings before upgrading. Between those, only hotfixes appear. Development is heavily concentrated in one maintainer's commit stream, with the rest of the contributor list handling docs, build scripts and individual plugins.

◆ Prediction

Given the cadence, the next build is likely months out and shaped by whatever the current test-build issue accumulates; the newly added MCU families are the obvious place for follow-up plugin and peripheral work.

Retool puts app testing in public beta a week after its app builder went GA.

◆ Current state

Retool's app builder went GA on October 28, building React apps from natural language, coding agents or imported code, with AI spend controls and credit packs alongside. Private npm registries for Enterprise apps and GPT 6.1 Terra followed. On November 3 testing for apps entered public beta, the first quality tool aimed at the apps the builder now produces.

◆ Where it's heading

Retool is surrounding generated apps with the controls a production team expects: spend limits, private packages, and now tests. Self-hosted stable channels keep taking quiet patch updates in parallel. The pattern points toward making AI-built apps something an engineering team can own and ship, not just prototype.

◆ Prediction

The entries do not say what app testing covers yet; expect follow-up notes on test types or CI hooks as the beta matures.
