5. A system, comprising:

at least one processor configured to:

determine that a client is to be updated;

in response to the determination that the client is to be updated, determine update packages for the client;

determine a user's preferred functions from among functions offered by the client based at least in part on record of operations of the user corresponding to the client, comprising to:

determine a number of times the user has used each function offered by the client within a designated time range based on the saved record of operations of the user corresponding to the client; and

successively select a designated number of functions, in sequence from the highest to the lowest number of times used, to serve as the preferred functions of the user, comprising to:

determine the designated number based on network environment information from the client and a preset mapping of network environment information to designated numbers;

determine update packages, from among the determined update packages, on which the user's preferred functions depend, to serve as preferred packages, comprising to:

determine whether a first update package of the update packages is related to a major vulnerability repair update package, wherein the major vulnerability repair update package relates to a normal operation of the client;

in response to a determination that the first update package of the update packages is related to the major vulnerability repair update package, assign a first weight to the first update package;

determine whether a second update package of the update packages is required for a preferred function among the preferred functions to operate normally;

in response to a determination that the second update package is required for the preferred function to operate normally, assign a second weight to the second update package; and

add the first update package and the second update package to the preferred packages based at least in part on the first weight and the second weight; and

release the preferred packages to the client to be updated; and

a memory coupled to the at least one processor and configured to provide the at least one processor with instructions.

6. The system as described in claim 5 , wherein the at least one processor is further configured to:

prior to the determining of the user's preferred functions from among the functions offered by the client:

receive the network environment information from the client.

7. The system as described in claim 5 , wherein the releasing of the determined preferred packages to the client to be updated comprises:

add package identifiers of the determined preferred packages to an update table;

assign a unique table identifier to the update table;

release the table identifier to the client;

add a released tag to the package identifiers of the preferred packages in the update table which have already been released to the client;

determine whether a table identifier transmitted by the client has been received; and

in response to a determination that the table identifier transmitted by the client has been received:

search the update table corresponding to the table identifier transmitted by the client; and

release packages corresponding to package identifiers to which the released identifier has not been added to the client to be updated.

8. The system as described in claim 5 , wherein the at least one processor is further configured to:

determine update packages, from among the determined update packages for the client, on which the preferred packages depend, to serve as dependent packages;

determine update packages, from among the determined update packages for the client, having importance weights greater than a predetermined threshold value to serve as mandatory update packages; and

release the dependent packages and the mandatory update packages to the client to be updated.

9. A computer program product being embodied in a tangible non-transitory computer readable storage medium and comprising computer instructions for:

determining that a client is to be updated;

in response to the determination that the client is to be updated, determining update packages for the client;

determining a user's preferred functions from among functions offered by the client based at least in part on record of operations of the user corresponding to the client, comprising:

determining a number of times the user has used each function offered by the client within a designated time range based on the saved record of operations of the user corresponding to the client; and

successively selecting a designated number of functions, in sequence from the highest to the lowest number of times used, to serve as the preferred functions of the user, comprising:

determining the designated number based on network environment information from the client and a preset mapping of network environment information to designated numbers;

determining update packages, from among the determined update packages, on which the user's preferred functions depend, to serve as preferred packages, comprising:

determining whether a first update package of the update packages is related to a major vulnerability repair update package, wherein the major vulnerability repair update package relates to a normal operation of the client;
