+This Log File records changes to the Indy Proposed Update since its initial publication
+
+2024/3/21 Updated Test/OpenSSL/openssl-client/TestClient.pas to avoid problem 
+          on Linux where -L option meant that the OpenSSL lib directory given 
+          on the command line was ignored.
+
+2024/3/25 Added OpenSSL FIPS Support. Missing from initial proposal, but present in earlier
+          versions of Indy. A new unit has been added IdSSLOpenSSLFIPS, and two new supporting
+          OpenSSL Header files: core and provider.
+          README.OpenSSL.FIPS.txt for more information.
+
+2024/3/25 Added support for Delphi "delayed" loading. If Indy is compiled with the
+          OPENSSL_USE_DELAYED_LOADING defined symbol then the static loading of a shared
+          library link model is implied and each OpenSSL library external declaration
+          includes the "delayed" directive. This should result in each such function only
+          being loaded immediately before it is first used.
+
+2024/3/25 Unit NTLMv2 updated to use new SSL Header Files and reference to old header files 
+          removed from IdDSNRegister.
+
+2024/3/26 Added missing units to indyprotocolsfpc.pas and fixed issues with cleaning the units
+          output directory used for fpcmake builds.
+
+2024/4/1  Reversed out delayed loading changes.
+
+2024/4/3  OpenSSL functions OSSL_PROVIDER_get0_default_search_path, OSSL_PROVIDER_load_ex and   
+          OSSL_PROVIDER_try_load in header file idOpenSSLHeaders_provider (introduced for FIPS support) 
+          had been incorrectly marked up as having been introduced in OpenSSL 3.0. They were
+          actually introduced in 3.2. This error result is a load library fail for 3.0 and 3.1.
+          This has now been corrected.
+
+2024/4/15 Fix for Issue #2 IdSSLOpenSSL - UTC_Time_Decode - convert to char should be PAnsiChar 
+          instead of PChar on Unicode. Patch include with updated comments. OpenSSL Test Programs
+          updated to include certificate notAfter and notBefore times in order to test patch and
+          provide regression test.
+
+2024/4/15 In IdOpenSSLHeaders_providers.pas, the OpenSSL functions introduced in OpenSSL 3.2 are
+          now only required for static library linking  if the defined symbol OPENSSL_3_2_ORLATER
+          is defined. This restores the ability for static linking with OpenSSL libraries for 3.0
+          and 3.1.
+
+2024/4/15 Issue 3 fixes to enable compilation with Delphi and target Linux64.
