## Security Notice
This release includes important security updates that address two significant CVE vulnerabilities affecting previous versions of the library. Users are strongly encouraged to upgrade to this version as soon as possible to benefit from these fixes and reduce exposure to the associated security risks.
The resolved CVEs are listed below:
• [CVE-2026-55869](https://www.cve.org/CVERecord?id=CVE-2026-55869)：Heap-Based Buffer Overflow in KMREQ Handling
• [CVE-2026-55868](https://www.cve.org/CVERecord?id=CVE-2026-55868)：Encryption State Machine Downgrade
## Security Improvements
• **PR #3317**：Implemented security improvements for KMREQ buffer validation. This fix addresses a vulnerability where received message sizes were not verified against the destination buffer size during the copy process. The update enforces word-aligned validation to prevent overflows when copying to internal arrays.
• **PR #3319**：Added strict validation of KMRSP wire length to prevent stack overflows.
• **PR #3324**：Resolved an OOB read in LOSSREPORT range parsing. The logic previously read a "HI" sequence number word following a "LO" marker without verifying if the "HI" word existed in the wire payload.
• **PR #3320**：Fixed an OOB read vulnerability in DROPREQ payload parsing. The handler now verifies that the wire payload meets the minimum 8-byte length requirement (two 32-bit sequence numbers) before attempting to process the request, preventing reads beyond the packet slot.
• **PR #3322**：Introduced a guard in `CRcvBuffer::dropMessage` to reject requested drop ranges that extend beyond the end of the receiver buffer.
## Important Bug Fixes
• **PR #3327**：Streamlined the library cleanup sequence by removing redundant post-cleaning of closed sockets. Architecture logic dictates that the Garbage Collector (GC) thread is the primary owner of socket deletion. Once the GC thread is joined, all sockets are considered deleted; further post-checks are unnecessary and avoid potential undefined behavior in cases where the library state might be corrupted.
• **PR #3310**：Fixed a segmentation fault (SEGV) occurring during global or static initialization when `ENABLE_HEAVY_LOGGING` was active.
## Build System Enhancements
• **PR #3300**：Transitioned the CI/CD pipeline to a robust Linux configuration matrix, serving as the modern replacement for Travis CI. The new system includes various platform and compiler combinations and incorporates specific fixes for MinGW builds and C++11 syntax compatibility.
## Documentation Updates
• **PR #3328**：Corrected a typographical error in the documentation regarding the separator used for `searchParameters`.
