v3.4.0

• Support writing header-only records and add tests for header-only records

v3.3.0

• Add ms3_msfp_init() to initialized MS3FileParam with start/end offsets.
• Avoid closing I/O streams not opened by the library when reading or writing miniSEED, specifically stdin and stdout or a provided descriptor.
• Update GitHub Actions dependencies for Node 24 changes.

Note

Behavior change: I/O streams provided by the caller, such as stdin and stdout, are no longer closed by the library.

v3.2.4

• Add ms_rlog_pop() to return messages from the error/warning log registry
• Fix return value from ms_rlog_emit()
• Fix tracking of message count in log registry.
• Add tests for logging facility.
• Add example/lm_extraheaders.c to demonstrate extra header functionality.

v3.2.3

• Add mseh_get_ptr_type() to determine type of an extra header.
• Add unsigned integer (uint64_t) support to mseh_set_ptr_r() and mseh_get_ptr_r().

v3.2.2

• Allow mseh_set_ptr_r() to create extra headers when none exist for a Merge Patch using the root pointer (""). Pointers to non-root locations still must exist. Recommend use for Merge Patch operations is to always use the root pointer ("") for consistency.

v3.2.1

• Rename ms3_mstl_init_fd() to ms3_msfp_init_fd() and add backward compatibility.
• Add -fPIC to the build options for the static library target.
• Update internal selection matching to support ! in addition to ^ for character class negation and handle edge cases more robustly.
• Avoid modifying record buffer during v3 CRC check and add CRC validation to testing.
• Add v3 parsing test for ensuring header-indicated lengths are sane.
• Small fixes of logic errors and increased portability.
• Add GitHub action to build and test on multiple platforms.
• Fix Windows symbol issues and CMake configuration.

v3.2.0

• Add generator-style packing interfaces for MS3Record and MS3TraceList. Specifically these interfaces:
  • msr3_pack_init(), msr_pack_next(), msr_pack_free()
  • mstl3_pack_init(), mstl3_pack_next(), mstl_pack_free()
• Fix mstl3_pack_ppupdate_flushidle() logic to flush only idle streams.
• Fix memory leak in mseh_replace().
• Addition of a CMake build system contributed by @lsawade, thank you!

v3.1.11

• Fix byte swapping in ms3_detect() for v3 records for big-endian systems. Thanks @gempa-jabe for reporting.
• Add MSF_SKIPADJACENTDUPLICATES to skip adjacent duplicate records while populating a MS3TraceList.

v3.1.10

• Add MSF_SPLITISVERSION flag to control using the splitversion value as the version instead the record publication version for mstl3_addmsr() and variants.
• Add missing functions to libmseed.def for Windows library exports.

v3.1.9

• Add mstl3_pack_ppupdate_flushidle() for packing idle streams in combination with the use of MSF_PPUPDATETIME during trace list additions.
• Convert mstl3_addmsr() from a macro to a real (thin) function.
