+# Pardus Release Support Lifecycle
+
+The support lifecycle for Pardus operating system releases consists of two phases:
+
+### Normal Support
+During this period, the relevant Pardus release receives feature updates, bug fixes, and security patches.
+
+### Security Updates Only
+This phase begins after the end of the normal support period. During this time, only critical security updates are provided; no new features or functionality are added.
+
+Once the security updates period ends, the release is considered **End of Life (EOL)**.
+

+
+### Pardus Release Support and Lifecycle Table
+
+| Pardus Release | Release Year / Debian Base | End of Normal Support | End of Security Updates (EOL) |
+|---|---|---|---|
+| Pardus 19 | 2019 (Based on Debian 10) | 2023.06.01 | 2024.06.30 |
+| Pardus 21 | 2021 (Based on Debian 11) | 2025.06.01 | 2026.08.31 |
+| Pardus 23 | 2023 (Based on Debian 12) | 2027.06.01 | 2028.06.30 |
+| Pardus 25 | 2025 (Based on Debian 13) | 2029.06.01 | 2030.06.30 |
+| Pardus 27 | 2027 (Based on Debian 14) | 2031.06.01 | 2032.06.30 |
+| Pardus 29 | 2029 (Based on Debian 15) | 2033.06.01 | 2034.06.30 |
+| Pardus 31 | 2031 (Based on Debian 16) | 2035.06.01 | 2036.06.30 |
+
+It is recommended that systems used in enterprise environments operate on Pardus releases that are within the **Normal Support** period or, at the latest, within the **Security Updates Only** period.
+
+No security updates are provided for Pardus releases that have reached **End of Life (EOL)**, and continued use of these releases poses a security risk.
+
+For releases whose support period has ended, migration planning to a newer Pardus release should be carried out.
