{productname} {release-version} also includes the following bug fix<es>:

// === <TINY-vwxyz 1 changelog entry>
// #TINY-vwxyz1
=== Improved handling of overlapping matches in abbreviation detection
// #TINY-11560

// CCFR here.
Previously in {productname}, an issue occurred during pattern matching where overlapping regular expression matches caused duplicated content when processing abbreviations. For example, in the string `D. dd.D.`, multiple overlapping patterns such as `D.`, `dd.D`, and a final `D.` could be incorrectly matched and processed more than once. This resulted in unexpected duplication in the editor, such as `D. dd.DDD.`.

This behavior was caused by insufficient overlap detection when identifying match regions, leading to multiple reinsertions of already matched substrings. The issue has now been resolved in {productname} {release-version} by refining the pattern-matching logic to accurately detect and avoid overlapping matches. The updated implementation ensures that each abbreviation is matched and processed only once, eliminating duplicated insertions and preserving the original content structure.

.Example before the fix:
[source,html]
----
<!-- Original content typed by the user -->
<p>D. dd.D.</p>

<!-- Result after pattern matching (incorrect behavior) -->
<p>D. dd.DDD.</p>
