v4.35.1 - Emergency Fix: HTTP 304 Handling

v4.35.1 - Emergency Point Release

Critical Bug Fix

This is an emergency point release fixing a critical bug that broke the primary API entry point.

Issue #519: HTTP 304 Not Modified Breaking Company(ticker) Lookup

Priority: P0 (Emergency)
Beads Issue: edgartools-4e1
GitHub Issue: #519

Problem

Company("MSFT") and all ticker-based company lookups were failing with the error:

Both data sources are unavailable

This occurred when the SEC returned HTTP 304 "Not Modified" responses (standard caching behavior).

Root Cause

The inspect_response() function in edgar/httprequests.py only accepted HTTP 200 status codes, treating HTTP 304 "Not Modified" responses as errors. HTTP 304 is a valid success response indicating that cached content is still valid.

Fix

• Updated inspect_response() to accept both 200 and 304 status codes
• Added comprehensive regression tests (7 new tests)
• All existing tests pass (42 httprequests and ticker tests)

Impact

✅ Fixes core functionality: Company(ticker) now works correctly with cached responses
✅ Restores beginner-friendly API: Primary documented entry point works as expected
✅ No breaking changes: All existing functionality preserved

Files Changed

• edgar/__about__.py - Version bumped to 4.35.1
• edgar/httprequests.py - Updated inspect_response() to accept 304
• tests/issues/regression/test_issue_519_http_304.py - New regression tests
