sed replace is giving me sore thumbs

I want to replace only the exact match of string inside the file with another value during the run time.

So,
I have a file filename.txt
where contents are:

Code:
version="1.0.7", 
url="https://google.com/_api/version=GBMaster"

now in my script
I have variable and tried to replace the value of that variable in version line with double quotes and comma.

Code:
new_version="1.0.7.1234567"
sed -i -e "s/version=.*/version="""$new_version""",/g"  filename.txt

the above kind of working, but it also replace the version in url and also not adding (double quotes) like below
Code:
version=1.0.7.1234567, 
url="https://google.com/_api/version=1.0.7.1234567"

I tried a lot variety of seds to make sure my file should only replace version= in version line not in URL.
that includes \< \> or ^. None of them are working.

I would like my o/p to be like below after sed
Code:
version="1.0.7.1234567", 
url="https://google.com/_api/version=GBMaster"

curl_global_init_mem(3) 					  libcurl Manual					   curl_global_init_mem(3)

NAME
curl_global_init_mem - Global libcurl initialisation with memory callbacks SYNOPSIS
#include <curl/curl.h> CURLcode curl_global_init_mem(long flags, curl_malloc_callback m, curl_free_callback f, curl_realloc_callback r, curl_strdup_callback s, curl_calloc_callback c ); DESCRIPTION
This function works exactly as curl_global_init(3) with one addition: it allows the application to set callbacks to replace the otherwise used internal memory functions. This man page only adds documentation for the callbacks, see the curl_global_init(3) man page for all the rest. When you use this function, all callback arguments must be set to valid function pointers. The prototypes for the given callbacks should match these: void *malloc_callback(size_t size); To replace malloc() void free_callback(void *ptr); To replace free() void *realloc_callback(void *ptr, size_t size); To replace realloc() char *strdup_callback(const char *str); To replace strdup() void *calloc_callback(size_t nmemb, size_t size); To replace calloc() CAUTION
Manipulating these gives considerable powers to the application to severely screw things up for libcurl. Take care! SEE ALSO
curl_global_init(3), curl_global_cleanup(3), libcurl 7.12.0 10 May 2004 curl_global_init_mem(3)
