Release v2.0.0 · shortbloke/Arduino_SNMP_Manager

First stable release of the 2.x API. Existing 1.x projects should read the
migration guide before upgrading.

Explain protocol acronyms, networking, and memory terminology in a plain-language
reference, with beginner guidance directly in the examples.
Explain setup, memory limits, and error recovery with editable example capacity
constants and actionable messages for incomplete tables.
Introduce SNMPClient and SNMPDevice with checked IPv4 strings, owned results,
automatic request IDs, bounded scheduling, batching, retries, and completion status.
Add range queries, selected-column tables, and interface traffic reads without
per-OID callbacks, addressing #28.
Support SNMPv1/SNMPv2c GET, GETNEXT, bounded walks and SET, plus SNMPv2c GETBULK.
Discover non-contiguous table indices and prefer Counter64 interface counters
with Counter32 fallback where high-capacity counters are unavailable.
Receive SNMPv1/SNMPv2c traps and acknowledge SNMPv2c INFORMs.
Add helpers for common MIB values and examples for interface traffic, host
storage, printer supplies, multiple devices, writes, and notifications.

Compile and link src/*.cpp; the library is no longer header-only.
Apply configuration macros consistently to the application and library through
build flags, rather than sketch-local defines.
Use named SNMP versions, fixed-width numeric destinations, signed 32-bit
request IDs, and mandatory capacities for text and OID buffers.
Make owning library objects noncopyable and require explicit handling of
bounded request capacity and cancellation.
Remove SNMPGet::setIP() and the library's definition of the transport-owned
UDP_TX_PACKET_MAX_SIZE macro.
Target modern ESP8266/ESP32 platforms; older AVR platforms are not supported.

Recover from lost or oversized GETBULK replies with GETNEXT after bounded retries;
reduce timed-out GET batches while leaving SET unsplit and unretried.
Allow more logical interfaces in the interface example with a bounded 64-row table.
Validate SNMP version/PDU/value combinations across the expanded manager
operations and enforce the protocol's OID arc-count limit.
Bound query, walk, table, packet, and payload storage; release invalidated
payloads and report allocation failures through checked results.
Support compact table-index storage and recover from empty successful GETBULK
responses using GETNEXT.

Cover large sparse NAS storage tables, wide size conversions, invalid allocation
units, bounded table overflow, and streaming in independent mock-agent regressions.
Add modular native regressions, independent mock agents, sparse-table fixtures,
low-heap failure tests, sanitizer and lifecycle/leak checks.
Build examples and library configurations for the supported ESP targets, and
validate wire interoperability against Net-SNMP.
Retain historical D1 Mini read/walk and burst-test evidence; those runs do not
certify this release on every board or agent.
Automate release preparation PRs and checked publication for both major lines.
Gate CI and releases with workflow/shell, Python, and Arduino packaging lint checks.

SNMPv3, DNS resolution, runtime MIB parsing, and sending traps/INFORMs are not
implemented. This is a bounded SNMPv1/SNMPv2c manager, not full SNMP conformance
certification.
