What is Protocol Buffers?
Protobuf is loading Edition 2026 with enforced defaults, one release candidate at a time.
The v35 and v36 cycles are almost entirely about Edition 2026. Naming-style enforcement arrived in 35.0, and 36.0-rc1 flipped default_symbol_visibility to STRICT and turned on descriptor-level proto limit enforcement for that edition. Alongside it, the build story consolidated hard — Bazel 7 dropped, Bazel 9 tested across every language runtime — and a JSON options surface (json_options.proto, json_name for enum values) is being propagated through C++, Java, Python and upb.
What is Agno?
Agno's whole visible changelog is one release, v2.7.3, split across six rows.
Every entry in this window is v2.7.3, dated 14 July 2026 — the feed publishes one row per change note rather than one per release, so a single version fills the timeline. The release adds ValkeyDb as an in-memory store for agent, team and workflow session state, RedmineTools for reading, creating, commenting on and logging time against issues, and wider human-in-the-loop confirmation, input and feedback support in AG-UI. The rest is MCP correctness: a clear error when a server is unreachable, and support for tools returning only structuredContent with no text block.

Protocol Buffers
6.3DEVOPS
Protobuf is loading Edition 2026 with enforced defaults, one release candidate at a time.
◆ Current state
The v35 and v36 cycles are almost entirely about Edition 2026. Naming-style enforcement arrived in 35.0, and 36.0-rc1 flipped default_symbol_visibility to STRICT and turned on descriptor-level proto limit enforcement for that edition. Alongside it, the build story consolidated hard — Bazel 7 dropped, Bazel 9 tested across every language runtime — and a JSON options surface (json_options.proto, json_name for enum values) is being propagated through C++, Java, Python and upb.
◆ Where it's heading
Editions are being used as a versioned policy channel: rather than break existing users, protobuf stages stricter defaults behind an edition label and lets projects opt in by declaring it. Each release adds another enforcement to the 2026 bucket while deprecating what it replaces — generic services, Reflection::GetEnum, reserving field number INT_MAX. The pattern is a compiler quietly acquiring a lint pass with teeth.
◆ Prediction
Expect 36.0 to go final with the Edition 2026 enforcement set frozen, and further additions to move to a 2027 edition rather than change 2026 after release. The deprecation warnings landing now — generic services, the enum reflection accessors — are the removals to expect in a later major.
Agno
6.3DEVOPS
Agno's whole visible changelog is one release, v2.7.3, split across six rows.
◆ Current state
Every entry in this window is v2.7.3, dated 14 July 2026 — the feed publishes one row per change note rather than one per release, so a single version fills the timeline. The release adds ValkeyDb as an in-memory store for agent, team and workflow session state, RedmineTools for reading, creating, commenting on and logging time against issues, and wider human-in-the-loop confirmation, input and feedback support in AG-UI. The rest is MCP correctness: a clear error when a server is unreachable, and support for tools returning only structuredContent with no text block.
◆ Where it's heading
The framework is filling in the operational layer rather than the agent abstraction. Session state gets a storage tier chosen for latency instead of durability, saving that state stopped making a model call it did not need, and MCP failures now surface legibly instead of as stack traces. Human-in-the-loop is being treated as a first-class interface concern in AG-UI rather than something callers build around. This is the work of a framework being run in production by people other than its authors.
◆ Prediction
Expect more storage backends on the ValkeyDb pattern and further MCP response-shape handling, since both are being driven by what breaks in deployment rather than by a roadmap visible in these notes.
