Techniques for updating a file using a multi-version patch file

A computing device configured to generate a multi-version patch file, the computing device comprising:

• at least one processor;
• and
• at least one memory configured to store instructions that, when executed by the at least one processor, cause the computing device to:
• modify a first file to produce a plurality of versions associated with the first file, wherein the plurality of versions comprises:
• (i) a latest version associated with the first file, and (ii) at least two previous versions relative to the latest version;
• identify a difference between the latest version and the at least two previous versions to produce first and second delta versions of the first file;
• and
• generate the multi-version patch file for installation by a client computing device, wherein the multi-version patch file (i) comprises the first and second delta versions, and (ii) causes a second file, that corresponds to the first file and stored on the client computing device, to be updated to the latest version using at least one of the first and second delta versions.

At least one non-transitory computer readable storage medium configured to store instructions that, when executed by at least one processor included in a computing device, cause the computing device to generate a multi-version patch file, by carrying out steps that include:

• modifying a first file to produce a plurality of versions associated with the first file, wherein the plurality of versions comprises:
• (i) a latest version associated with the first file, and (ii) at least two previous versions relative to the latest version;
• identifying a difference between the latest version and the at least two previous versions to produce first and second delta versions of the first file;
• and
• generating the multi-version patch file for installation by a client computing device, wherein the multi-version patch file (i) comprises the first and second delta versions, and (ii) causes a second file, that corresponds to the first file and stored on the client computing device, to be updated to the latest version using at least one of the first and second delta versions.
