environment variable have been plugged.

173
+ * The wincred credential helper has been updated to avoid memory
174
+ corruption when erasing credentials and to prevent silent
175
+ credential loss when storing OAuth tokens, by correcting buffer
176
+ allocations and arguments passed to safe-CRT APIs.
177
+ (merge f635ab9ab4 js/wincred-fixes later to maint).
178
+
179
+ * Various code paths that initialize a cryptographic hash context but
180
+ bail out or finish without calling 'git_hash_final()' have been taught
181
+ to call 'git_hash_discard()' to release allocated resources, fixing
182
+ memory leaks when Git is built with non-default backends like
183
+ 'OpenSSL' or 'libgcrypt'.
184
+ (merge 600588d2aa jk/hash-algo-leak-fixes later to maint).
185
+
186
+ * Various resource leaks, invalid file descriptor closures, and process
187
+ handle ownership issues flagged by Coverity have been fixed.
188
+ (merge 9184231173 js/coverity-fixes later to maint).
189
+
190
+ * Dockerized CI jobs running in private GitHub repositories have been
191
+ adjusted to use explicit process and file limits, preventing resource
192
+ exhaustion errors on private runners.
193
+ (merge bad766fbac js/ci-dockerized-pid-limit later to maint).
194
+
195
+ * Various test scripts have been updated to clean up large temporary
196
+ files and repositories, reducing peak disk usage during testing.
197
+ Also, expensive tests have been disabled on platforms that lack
198
+ sufficient resources (like 32-bit platforms and Windows CI runners),
199
+ and the long test suite has been enabled in GitLab CI.
200
+ (merge 84248444ad ps/t-fixes-for-git-test-long later to maint).
201
+
202
+ * The UTF-8 precomposition wrapper on macOS has been updated to use a
203
+ flexible array member to represent the name of a directory entry,
204
+ preventing fortified libc checks from failing when the name is
205
+ reallocated to be larger than 'NAME_MAX' bytes.
206
+ (merge 1eb281159f ih/precompose-flex-array later to maint).
207
+
208
+ * The 'git_hash_*()' wrappers have been updated to be used consistently
209
+ across the codebase instead of direct calls to members of 'struct
210
+ git_hash_algo', and 'git_hash_discard()' has been made idempotent to
211
+ simplify cleanups.
212
+ (merge 9e396aa553 jk/git-hash-cleanups later to maint).
213
+
214
+ * The sideband demultiplexer has been updated to recognize ANSI SGR
215
+ escape sequences that use colon-separated subfields (e.g., for
216
+ 256-color or true-color codes).
