What is Coolify?

Coolify is in a sustained security-hardening run while the v4 beta inches forward.

Coolify is releasing roughly weekly beta builds dominated by security and reliability work: mass-assignment protection, query scoping, input validation, encrypted webhook secrets, accidental-prune protection. Each release also slips in small bug fixes and the occasional new service template. The same release is published across two feeds, so duplicates are common in the changelog.

What is ESP-IDF?

The 6.1 candidate arrives carrying the same notes the beta already shipped in June.

ESP-IDF maintains at least five branches concurrently — 5.2, 5.4, 5.5, 6.0 and the 6.1 line, which has now moved from beta to release candidate. The release entries are mostly installation instructions, with the substantive changelog deferred to Espressif's separate release notes site. Where detail does surface it is narrow and specific: v5.5.5 introduced CONFIG_SPIRAM_ENC_EXEMPT with a MALLOC_CAP_SPIRAM_NO_ENC capability for carving an unencrypted PSRAM region, and v5.2.7 changed OpenThread examples to require an ot prefix on CLI commands.

2.5

Coolify is in a sustained security-hardening run while the v4 beta inches forward.

◆ Current state

Coolify is releasing roughly weekly beta builds dominated by security and reliability work: mass-assignment protection, query scoping, input validation, encrypted webhook secrets, accidental-prune protection. Each release also slips in small bug fixes and the occasional new service template. The same release is published across two feeds, so duplicates are common in the changelog.

◆ Where it's heading

The product is hardening for production self-hosted use rather than expanding feature surface. Several recent fixes — team-scoped queries, locked properties, encryption for secrets — are the kind of multi-tenant defenses that matter when self-hosted PaaS instances start hosting more than one team's workloads. The v4 beta is converging toward stable, but security debt is still being paid down before that happens.

◆ Prediction

Expect a v4 GA cut once the security backlog drains and the new-template flow stabilizes, plus an explicit audit/security advisory listing the hardening work. New service templates will continue to drip in opportunistically.

2.5

The 6.1 candidate arrives carrying the same notes the beta already shipped in June.

◆ Current state

ESP-IDF maintains at least five branches concurrently — 5.2, 5.4, 5.5, 6.0 and the 6.1 line, which has now moved from beta to release candidate. The release entries are mostly installation instructions, with the substantive changelog deferred to Espressif's separate release notes site. Where detail does surface it is narrow and specific: v5.5.5 introduced CONFIG_SPIRAM_ENC_EXEMPT with a MALLOC_CAP_SPIRAM_NO_ENC capability for carving an unencrypted PSRAM region, and v5.2.7 changed OpenThread examples to require an ot prefix on CLI commands.

◆ Where it's heading

The branch count is the product decision here: hardware shipped years ago stays supported, so the 5.2 line still receives breaking changes to its examples while 6.1 moves toward release. The 6.1 pre-releases are where the real disclosure sits — a long breaking-change list covering SPI flash headers moving to private visibility, mbedTLS 4.1.0 dropping 192-bit curve support in secure boot, ECDSA Secure Boot V2 disabled on ESP32-H2, C5 and P4 over a vulnerability, and a default ESP32-P4 chip revision bump to v3.0. That list has not changed between beta1 and rc1, which suggests the 6.1 scope is settled.

◆ Prediction

A final v6.1 release should follow the candidate, with patch releases continuing across the 5.x lines in the meantime.
