Breaking Changes in v1.0.0 Beta

# This was supported in v0.x
config = {
    "version": "v1.0"  # ❌ No longer supported
}

result = m.add(
    "memory content",
    user_id="alice",
    output_format="v1.0"  # ❌ No longer supported
)

# v1.1 is the minimum supported version
config = {
    "version": "v1.1"  # ✅ Required minimum
}

result = m.add(
    "memory content",
    user_id="alice"
    # output_format parameter removed
)

ValueError: The v1.0 API format is no longer supported in mem0ai 1.0.0+.
Please use v1.1 format which returns a dict with 'results' key.

result = m.add("content", user_id="alice", output_format="v1.1")
search_results = m.search("query", user_id="alice", output_format="v1.1")

# Optional async mode
result = m.add("content", user_id="alice", async_mode=True)
result = m.add("content", user_id="alice", async_mode=False)  # Sync mode

# Always async by design, parameter removed
result = m.add("content", user_id="alice")

# For async operations, use AsyncMemory
from mem0 import AsyncMemory
async_m = AsyncMemory()
result = await async_m.add("content", user_id="alice")

# Could return different formats based on output_format parameter
result = m.add("content", user_id="alice", output_format="v1.0")
# Returns: [{"id": "...", "memory": "...", "event": "ADD"}]

result = m.add("content", user_id="alice", output_format="v1.1")
# Returns: {"results": [{"id": "...", "memory": "...", "event": "ADD"}]}

# Always returns standardized format
result = m.add("content", user_id="alice")
# Always returns: {"results": [{"id": "...", "memory": "...", "event": "ADD"}]}
