What is Apache TomEE?

A Jakarta EE server whose changelog is mostly dependabot — until EE11 moved to main

TomEE ships a steady stream of 10.1.x and 10.2.0 patch releases whose release notes are dominated by dependency bumps and regenerated BOMs, with one or two real TOMEE- ticket fixes buried in each. The genuinely new thing is 11.0.0-M1, the first milestone of the next major line, created when Jakarta EE 11 work moved onto the main branch. The 10.x line continues in parallel as the stable target.

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.

Apache TomEE vs ESP-IDF: editorial side-by-side

A2.5

A Jakarta EE server whose changelog is mostly dependabot — until EE11 moved to main

◆ Current state

TomEE ships a steady stream of 10.1.x and 10.2.0 patch releases whose release notes are dominated by dependency bumps and regenerated BOMs, with one or two real TOMEE- ticket fixes buried in each. The genuinely new thing is 11.0.0-M1, the first milestone of the next major line, created when Jakarta EE 11 work moved onto the main branch. The 10.x line continues in parallel as the stable target.

◆ Where it's heading

The project is running the classic app-server two-track pattern: keep 10.x boring and current on its dependency surface, while the EE11 rearchitecture accumulates on main behind milestone tags. Nearly all visible energy goes into staying aligned with Tomcat, ActiveMQ, Hibernate, Jackson and MicroProfile versions — which for a server whose value is spec compliance is the actual product work, not a distraction from it.

◆ Prediction

Expect further 11.0.0 milestones with EE11 certification as the gate, while 10.1.x/10.2.x continue absorbing upstream dependency updates and isolated ticket fixes.

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.
