116 + * The repository discovery and repository configuration phases, which

117 + were previously intertwined in 'setup.c', have been split. Repository

118 + discovery has been updated to populate a 'struct repo_discovery'

119 + without modifying the repository state, which is then taken by

120 + repository configuration to initialize the repository, paving the way

121 + for clean unification of repository configuration.

122 +

123 + * The 'SubmittingPatches' document has been updated to explicitly

125 + patch series when they are no longer pursuing it.

126 +

127 + * The contributor guide has been updated to advise new contributors to

128 + trim irrelevant quoted text when replying to review comments, matching

130 +

131 + * The build system has been updated to support building universal macOS

132 + binaries when 'Rust' is enabled, by compiling separate static archives

133 + for each target triple listed in 'RUST_TARGETS' and combining them

134 + using the macOS 'lipo' tool. The 'git-credential-osxkeychain' helper

135 + has been updated to link against '$(RUST_LIB)' when 'Rust' is enabled.

136 +

137 + * The test suite has been updated to use the 'test_grep' helper instead

138 + of bare 'grep' for test assertions, allowing file contents to be

139 + printed on failure for easier debugging. A new 'greplint' linter has

140 + been introduced to detect and prevent new bare 'grep' assertions from

141 + being added to the test suite.

142 +

143 + * The pipelines in 't1410-reflog.sh' have been replaced with the

144 + 'test_stdout_line_count' helper to avoid suppressing the exit code of

145 + 'git' commands, ensuring failures are not hidden from the test suite.

146 +

147 + * The cache-scanning loop in 'next_cache_entry()' has been optimized

148 + to avoid rescanning already-unpacked index entries, preventing a

149 + quadratic performance slow-down when diffing the working tree

150 + against a commit with a pathspec matching early index entries.

151 +

152 + * The global configuration variable 'ignore_case' (representing the

153 + 'core.ignorecase' configuration) has been migrated into 'struct

154 + repo_config_values' to tie it to a specific repository instance.

155 +

156 + * The performance of ref updates and reads using the 'reftable' backend

157 + in the presence of many deletion tombstone records has been optimized

158 + by removing the tombstone suppression flag from the merged iterator

159 + and instead skipping tombstones at higher-level call sites where
