Full Changelog: v1.4.56...v1.5.0

v1.4.56

Bugfixes

• Shm: detect and error on duplicate region IDs (by @rbx in 42ce691)
• Examples: fix incorrect config (by @rbx in a982d60)

Misc

• Shm: improve debug output (by @rbx in c3b273c)
• Test: add test for externally created region (by @rbx in 16275db)

Full Changelog: v1.4.55...v1.4.56

v1.4.55

Bugfixes

• Shm: fix an issue in shmem region initialization, where a local region object would get created but immediately destroyed because a remote region object with the same ID already exists. Furthermore, the existing object would get marked as local, but with wrong configuration, leading to potential unexpected behavior. (by @rbx in af0d668)

Misc

• region example: add options for testing with externally-created regions by @rbx in f5c46ce
• shm: add some debug output by @rbx in 072d7cb
