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.

What is Tigris?

Tigris still ships features inside essays, and the newest one is a recycle bin.

The feed is a blog, not a changelog, and each post is an engineering argument that happens to carry a product change. This window has three: a recycle bin for objects and buckets built on immutable storage so deletion in a geo-replicated active-active system stops meaning data loss, agent-native onboarding via tigris init --agent, and a CLI that migrates an entire bucket from any S3-compatible provider in one command. The rest are essays on SigV4, presigned URLs, and ClickHouse restore economics.

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.

5.0

Tigris still ships features inside essays, and the newest one is a recycle bin.

◆ Current state

The feed is a blog, not a changelog, and each post is an engineering argument that happens to carry a product change. This window has three: a recycle bin for objects and buckets built on immutable storage so deletion in a geo-replicated active-active system stops meaning data loss, agent-native onboarding via tigris init --agent, and a CLI that migrates an entire bucket from any S3-compatible provider in one command. The rest are essays on SigV4, presigned URLs, and ClickHouse restore economics.

◆ Where it's heading

Two arguments run underneath everything: object storage should be the durable state layer for agents, and S3 compatibility is a surface to be explained rather than merely claimed. The SigV4 and presigned-URL posts are the second argument in practice — publishing where the protocol is dangerous is a credibility play against the incumbent. The recycle bin extends the immutability story into a place immutable systems usually struggle, which is undoing a mistake.

◆ Prediction

Expect more posts that pair a protocol critique with the Tigris behavior that answers it; the egress-cost framing from the ClickHouse post is the one most likely to recur as a paid migration path.
