Custom macro libraries using SOCKET or TCPIP access methods break because of the HTTPS default.
Legacy authentication (NTLM, basic auth) to external databases fails unless reconfigured for OAuth or Kerberos.
Stored processes using _WEBOUT with hardcoded HTTP redirects need review.

Enhanced Deployment Tools: The SAS Deployment Manager has been streamlined to handle hotfixes and updates more efficiently, reducing downtime during maintenance windows. Custom macro libraries using SOCKET or TCPIP access

HTTPS-only default communication between SAS middle-tier and compute servers, deprecating legacy HTTP bridges that have been attack vectors for two decades.
Enhanced Unicode support (UTF-8 as a default session encoding option), finally reducing the painful ENCODING mismatches that plagued multi-language data integration.
64-bit memory addressing improvements that allow individual SAS sessions to address more than 2TB of RAM, crucial for large in-memory analytics like PROC HPLOGISTIC and HPFOREST.

SAS Studio 5.2 performance – Slower initial load for large Git repositories. Workaround: limit repository clones to active working branches.
ODS EXCEL memory usage – Exporting >1M cells can cause the SAS Workspace Server to exceed memory. Workaround: use DBMS=XLSX in PROC EXPORT for pure data; use ODS EXCEL only for formatted reports.
TLS 1.3 with legacy Java applications – Some Java 8 clients cannot negotiate TLS 1.3. Workaround: configure SAS to allow TLS 1.2 as a fallback via the -ssltls option in sasv9.cfg.
